Reverse-Engineering the Security Module in a Mastervoice Butler in a Box CelGenStudios 2023-07-05 | For as little time as I've had with the Butler, I'm amazed how much effort they put into making sure a discarded or stolen unit was unusable. A "PIN" is required to unlock the unit whenever it is powered on after a battery failure. That PIN is almost never written on the unit itself and probably hides in a black brick of potting compound found inside every unit. I've taken care of the de-potting process already. After some analysis, here is what I have discovered so far. I doubt Mastervoice cares about me digging into their product like this. At least, not 30 years later. :PRemember to follow me on Twitter at @CelGenStudios to keep up to date on what I am doing and what might be happening in the next video.
Xerox CAT - The Earliest of the Trackpads CelGenStudios 2024-10-12 | While its known that Xerox used the Mouse for the Alto, what's considerably less remembered is that in 1980 Xerox experimented selling a word processor with what I can tell is the earliest trackpad designed to move a cursor with your fingers and to do so in a shipping commercial product. (IE: anyone who could afford it could buy one). At a notable expense I've come into ownership of one. Not the whole system, so I can't demonstrate it working. Just the pad and the interface board.In this video I will try to explain why if you search for what the first trackpad is you will run into a confusing mix of history, how with no evidence I suspect this was a pet project of someone at PARC and we look at the hardware itself.I will be truthful right now that while I have attempted to research this and get as much as my information correct, there are many holes in what I could find and I will likely of made a mistake or two. I am more than willing to read anything you wish to add to what I've found in the comments.For more information on the Xerox 860, the Digibarn has a page on their machine - digibarn.com/collections/systems/xerox860/index.htmlHere is a very old (but somewhat recently uploaded) video of the same system.

From the Pocket to the Car - Motorolas DynaTAC Car Kit CelGenStudios 2024-09-29 | For the businessman or individual always on the go but not wanting to be fussing with his mobile telephone while driving OR owning two different mobile telephones, Motorola offered its customers a car kit that not only stored their phone in a secure location while charging the battery but converted it into a fully-featured car phone as well, with hands-free speakerphone and external antenna connectivity.I was lucky enough to stumble across (most of) one and seeing how there's no mention of these kits anywhere online, lets go through what came in the package and how it went together.Remember to follow me on "X" at @CelGenStudios to keep up to date on what I am doing and what might be happening in the next video.

AMC ET-501 - Engine Computer Diagnosis in the 1980s CelGenStudios 2024-07-20 | We have it pretty easy now for diagnosing Engine Management problems. AMC on the other hand decided to make it hard, then release this handy tool to solve it. Lets go through the AMC/OTC collaborative effort that was the ET-501 Fuel Feedback System Tester, what comes in the kit and how it all works.I have scanned and uploaded the manual for the tool to the Internet Archive. you can find it here: archive.org/details/amcet501instructionmanualThe 4 and 6 cylinder diagnostic ROMs have also been dumped and uploaded to the same place: archive.org/details/amcet501romimages(When burning them to now EPROMs, be aware of pin orientation!)About ten minutes into the video I mention the later Bendix and Renix computers used in Jeep/Renault vehicles at the time for fuel injection. Neither do I own vehicles that use those systems or the diagnostic tools that were available for those near the end of AMC's life but I have been given access to training laserdiscs which discuss it and the MS 1700 diagnostic tool.

Cartel CT-1000 - The Bluetooth Car Kit that wants to be a Car Phone CelGenStudios 2024-07-06 | Car Phones have long gone the way of the Dodo and now roam the planet as static props in luxury classic cars. There have been modern takes on adapting these old phones to work with modern phones but only once that I can find was there ever a commercial product that gave you the look and feel of a car phone while actually being just a hands-free Bluetooth device. Lets take a look at the rather expensive and uncommon CT-1000 and see if it lives up to the name.Cartel Mobile Solution's Website (as of 2016. The last year the site was still up) - web.archive.org/web/20160625043103/http://www.bluecarphone.com/index.phpA simplified guide and the wiring diagram for the CT-1000 can be found here - archive.org/details/ct1000-instAs far as I can tell, this is the full Users Manual provided by CarTel and submitted to the FCC - archive.org/details/car-tel-ct-1000-user-manualHere's UselessPickle's finished Bleutooth adapter for the Mitsubishi DiamondTel - youtube.com/watch?v=52AuhS5Jq0QAgain, I'm not downplaying in the video that he should of done something better or more common and therefore his work is not interesting. (or at least in editing I felt I was sounding too negative) The fact remains nobody has tried this on their own before him and succeeded. 1 is more than 0. I still strongly appreciate and respect the work he put into how clean it is.

Tantalum hunting with a Thermal Imaging Camera CelGenStudios 2024-06-22 | Tantalum is never fun to deal with because when it shorts and DOESN'T explode you end up with a whole bunch of them running parallel in the same circuit. With the ever dropping price of thermal imaging cameras however using only a current limiting bench supply we can easily isolate the problem capacitor.

All about Timing - Correcting and Adjusting your 258s Spark Advance. CelGenStudios 2024-05-25 | We trust a mechanic to know what they are doing. After all, they went to school for this. Sometimes mistakes are made and they are hard to notice.In this video I discover that a previous (and poorly done) engine installation had the engine broken in and run (part of this is my fault for reasons I explain in he video and I won't deny that) with a mere 5 degrees of spark timing BTDC. On an AMC straight-six with no computer this is "okay" but a 258 with Computerized Engine Control needs 15 degrees (or a few degrees less as you go up in altitude) or as it turns out, the engine runs but wow it feels anemic.We'll be following AMC Service Bulletin I.S. 12E, instead of the 1982 AMC Technical Service Manual to check and adjust the engine timing. You can find it on the Internet Archive.archive.org/details/is-12-e/mode/2upThis bulletin is especially important for 1982 model vehicles (not jsut the Eagle!) as I have found the instructions commonly shared from the TSM results in an unacceptably incorrect timing. We'll be using a Sun Modular Engine Analyzer and its variable timing light to more easily show what I'm doing. For you at home all you need is a handheld precision tachometer and a standard induction timing light. I strongly advise against the old fashioned "set the ignition timing with a vacuum gauge" method. A second person to assist is also strongly suggested, especially for in-Drive idle adjustments, which must be done after the timing is adjusted.Remember to follow me on "X" at @CelGenStudios to keep up to date on what I am doing and what might be happening in the next video.
Four-Phase systems - The Expansions, the Cables and the Future - Part 2 CelGenStudios 2024-05-11 | The second and last part of our look through my System IV/70, it's IV/90 expansion, the NP-80 Peripheral Controller and the many cables and lesser bits and pieces I own. Unfortunately due to missing major components I will not be able to demonstrate the system further at this time or in the foreseeable future.If you have not seen Part 1, you can find it here - youtu.be/un5THZYmqHEAll currently known to exist (as of May 2024) documentation, schematics and component photographs (enclosures, boards, cables etc.) can be found here on Bitsavers - http://www.bitsavers.org/pdf/fourPhaseLike I mentioned in the video, archiving everything at this point is essential, considering there is nearly nothing left. If you cannot reach me by email you can always reach me through X, the VCFed Forums and of course there are the countless other old tech gurus who may also be able to assist with many of them also having their own means which they can be contacted.(Big shout-out here to fellow YouTuber Forgotten Machines!)I would like to thank the Four-Phase systems Facebook Group for providing photographs and some images in this series along with their insight into the company and they products they made. I would also like to thank the Museum of Information Technology at Arlington (MITA) for additional support, plus a thank you to the other folks who put their two cents in however asked not to be mentioned.Remember to follow me on "X" at @CelGenStudios to keep up to date on what I am doing and what might be happening in the next video.
May 1 have a Drink? - Vending Spring Startup CelGenStudios 2024-05-01 | I'll be honest. I have not actually run this machine for two years. Too busy playing financial catch-up to bother keeping the machine stocked and running. This year however I think I've caught up enough I can do exactly that. I'll give it a quick one-over, then load it up.(PSA: Really this video is just me seeing how well the cheapest lavalier microphone on Aliexpress sounds when plugged into a HERO2. It's actually really good compared to the internal mic!)
Four-Phase systems - The Creator, the Company and the System IV/70 Computer - Part 1 CelGenStudios 2024-04-27 | In 2022 I came across a computer I had only heard of once before in my life. A year and a half later I think I've gone through enough of what remains known on the Internet to talk a little more about what I found. This is the System IV/70 ("Four-Seventy") computer and this is the remarkable history behind the microprocessor that makes it run, the AL1. Lets talk about everything Four-Phase and go through what lives inside my system.Ken Shirriff's blog on AL1 and it's importance in the early world of microprocessors alongside the Texas Instruments TMX1795 can be found here - http://www.righto.com/2015/05/the-texas-instruments-tmx-1795-first.htmlMore information on Lee Boysel and the early history of microprocessing can be found here along with more details on the famous courtroom demonstration: https://ece.engin.umich.edu/stories/lee-boysel-the-early-history-of-microprocessingAn early brochure from Four-Phase Systems covering their computer, it's optional capabilities and its software options is available here - computerhistory.org/brochures/d-f/fourphase-systems-incHigh-resolution (multi-megabyte) photographs of all the boards seen today in the video are now available on Bitsavers - http://www.bitsavers.org/pdf/fourPhase/Pictures/11001131-C_BACKPLANE_and_CHASSIS(Thank you Bitsavers for archiving this!)Interestingly, Four-Phase Systems seem to of fallen into a historical black hole. Almost no systems still exist and likewise documentation, software, hardware and technical papers are hard to come by. I have been working on efforts to help locate and digitize items as I can (affordably) come across them before the system becomes completely extinct but I'm always willing to find more. If you wish to reach out to me regarding Four-Phase systems I can be reached by email, an ongoing thread on the VCfed forums or other archival operations such as Bitsavers or the Vintage computer Federation are willing to help in whatever way we can.Finally I would like to credit the Museum of Information Technology at Arlington and the Four-Phase Facebook users group both for providing information and photos, along with other former employees who wish to remain anonymous. Without your historical momentos there would be much, much less to research about this otherwise forgotten machine.Remember to follow me on "X" at @CelGenStudios to keep up to date on what I am doing and what might be happening in the next video.

Kodak EktaPro EM 1000 - Kodaks Affordable High-Speed Camera from the 90s CelGenStudios 2024-02-17 | High-speed cameras are still several thousand dollars. Thankfully that's pennies compared to the cost of the first solid-state imagers that emerged on the market at the end of the 80's and starting into the 90's. The EktaPro EM 1000 came in at around $100000 (varying by configuration) and provided 1.2 seconds of record time at 1000fps. Today they can be found for a few hundred if you are lucky. Lets take a look at my base model machine and then I will show you some of the footage I've taken with this unit so far.Through this video I repeatedly mention fellow Youtuber and engineer Tesla500 for inspiring me years ago to investigate buying one of these imagers. Since he has already gone through his already, look below for more videos from him:-His teardown of the image processor and the imager head: youtu.be/PYyF39AnKG0-A later video in which he does a teardown of the remote control and tests the imager itself: youtu.be/L75LxwbOHVo-He alludes to a more higher-end imaging processor at one point called the Hi-Spec. Same design but a new durable rackmount enclosure.

Canon L2 - The Super weird and Super Expensive Camcorder I wanted 20 Years Ago CelGenStudios 2023-12-25 | Back when I first started shooting videos in the early 2000's I wanted to get *one* camera. The Canon L2 Professional Camcorder is perhaps the most high-end camera that was ever released to the Consumer and Prosumer market. After 20 years of trying to get one I finally did!Let's go through the very fancy Pelican case and see what kind of a camera and accessories I bought for $350CAD, then lets talk a little on two markets that ended up really making this camera a must-have for top-end Hi-8 users.(Update: YES I am ware I bungled the zoom factor when mentioning the VL-EOS adapter.

Keytronic Foam and Foil Pads - How to Make Them Yourself CelGenStudios 2023-09-30 | There are many computers and terminals out there in the world still that use keyboards and buttons manufactured by Keytronic. These devices use a capacitive surface with a soft foam backing in place of a more complicated switch mechanism. With time these assemblies fail and need to be replaced.In 2023 there is two or three major vendors selling replacement pads. The most notable of the group is Texelec. Due to the success of their product I have found that availability can at times not be assured. If you are looking to re-pad a quantity of keyboards the cost can also add up quickly.For those of you who do not mind the extra effort or sourcing the materials and tools here is a method I developed several years ago which initially I used on my Apple Lisa and subsequently another half dozen machines over the years. While the "feel" of the key might be different, I just don't care. I need working keyboards.Please note that in the video I list sources for the foam and the Mylar sheets. While availability might be a problem where you live and work, these materials should at least be a good reference for you to find a substitute.Remember to follow me on "X" at @CelGenStudios to keep up to date on what I am doing and what might be happening in the next video.

This was stuff so fresh it was still hot from the oven. Here I am using the exact same concepts decades later and either they are exactly as they were proposed, or it's a new iteration and we've superseded the original idea with something better)I sit down at my desk on September 1, 2023. I want to read Popular Science, but I want to look at it 30 years agoSo I open a window on my computer and look through a graphical index of issues, sorted by decade and month within the decadeI choose September 1993. It opens the entire issue on my screen. Now I can scroll through the pages with my mouse. If I was on my tablet I could use my finger.I find an advertisement for "Beyond 2000". It's on the Discovery Channel. Hmm, that sounds like something neat to watch.So in the same program I open a "tab" and use a "search engine" to look across the Internet for more information on this TV series. I pull up a description and photographs from various episodes. Finally I choose from a list an entire episode and watch it full-screen
IBM System/32 - The Arrival and Assembly CelGenStudios 2023-09-02 | At last! :DAfter casually keeping an eye out since 2004* I finally came across a System/32! At this point it's more of a collectors piece (and a big one at that) but this finally fits into the slot that I left open for a 70's era IBM system that is both small and still somehow functional in a residential environment.Actually getting it in the house is something for another day, but for now lets put this machine back together after I had to pull it apart to transport it. I'll show you around and explain some of the hardware along the way!The Corestore's FIRST System/32 - http://www.corestore.org/32.htmThe Corestore's SECOND System/32 - http://www.corestore.org/32-2.htmAll the documentation you could ever dream of for the System/32 - bitsavers.org/pdf/ibm/system32*(Don't ask why at 14 years old I wanted an IBM computer like this. It was a weird time for me...)Remember to follow me on "X" at @CelGenStudios to keep up to date on what I am doing and what might be happening in the next video.
VCF West 2023 - As seen through a Camcorder CelGenStudios 2023-08-19 | Now Available in HD - youtube.com/watch?v=77bHHDdayrcI was given a challenge.In 2019 I took a tube camera and VHS-C tape machine to LTX. In 2023 I was told it's easy to shoot HD, so why not use a MiniDV camera instead?Alright, lets do this. Here is two days of VCF West in Mountain View California, as seen through a Sony DSR-PD170 fitted with a cheap Century fisheye lens and an excessively sensitive microphone.For more information on the Vintage Computer Festival, check out the links below:en.wikipedia.org/wiki/Vintage_Computer_Festivalvcfed.org/events/vintage-computer-festival-westRemember to follow me on "X" at @CelGenStudios to keep up to date on what I am doing and what might be happening in the next video.
Road Trippin - Do I have a 300W Inverter that Doesnt Suck? CelGenStudios 2023-08-05 | When you have requirements beyond a laptop charger, DC automotive inverters start to get weird. I just need an inverter that can do peak 300 watts, a stable voltage and most importantly, a locked line frequency.I'm going to pull out a bunch in inverters (most of then are junk) and find out which one will be "good enough" for this road trip to VCF West.Keep in mind this video will NOT dig deep into the science of AC inverters and the alternate universes of pure sine wave, semi-sine or chopped.Remember to follow me on "X" at @CelGenStudios to keep up to date on what I am doing and what might be happening in the next video.
Sun Modular Engine Analyzer 1500 - Setup and Operation CelGenStudios 2023-07-26 | Since the main video on this is almost an hour long I made this second video that's a more manageable at eleven and a half minutes long.In this video We'll just make the connections and perform most of the tests.Remember to follow me on Twitter at @CelGenStudios to keep up to date on what I am doing and what might be happening in the next video.
Sun Modular Engine Analyzer 1500 - Old Fashioned Engine Diagnostics CelGenStudios 2023-07-22 | Before there was the magic of OBD there were very few ways to track down engine running and performance issues on their own. This machine was often rented or leased to shops to help speed up diagnosing these issues. Some places bought them outright for many thousands or tens of thousands of dollars each. Today not a lot of people know how they work or what they do and generally if you can load it into a car they sell for nothing (in 2023) so lets go on an adventure to pick it up, go over the components of the unit and attach it to a vehicle to demonstrate how it works.I mention in the video that scanned copies of the manual, service manual and leaflets for the various accessories are available online.

Hughes Probeye - A Thermal Imaging Camera From the 70s CelGenStudios 2023-06-24 | While this looks like some sort of surveyor's tool or perhaps a device for marine navigating by stars, this orange box is in fact the oldest thermal imager I have ever seen. For reasons I will explain in the video we will not be able to try it out but lets go over it anyways to see how it works.In this video I do however demo what it *should* look like if it it WAS working.

Joes Hot Dog Stand - Rebranded, poorly built junk CelGenStudios 2023-06-10 | Normally I don't like to do product reviews on modern products but this one was so dumb I thought why not, lets have some fun.There was nothing fun about this. It was a pile of flimsy plastic, poor design considerations and terrible to clean. This is Joe's Hot Dog Stand. I don't recommend it unless you want a throwaway appliance.Remember to follow me on Twitter at @CelGenStudios to keep up to date on what I am doing and what might be happening in the next video.
Dana Speedostat - Control Cable and Potentiometer Replacement CelGenStudios 2023-05-27 | Under normal circumstances the cable exiting the vacuum servo should *never* be pulled on or allowed to support the weight of any object. When it is, often you will either break the cable and destroy the potentiometer that serves to tell the controller where the cable positioning is.There are no substitutes for many of these parts. Lets pull several servos apart to repair my cruise control.Remember to follow me on Twitter at @CelGenStudios to keep up to date on what I am doing and what might be happening in the next video.
Pre-Paid Electricity - The Smith Coin-Operated kWh Meter CelGenStudios 2023-05-13 | As a resident of North America I never expect to pay for electricity before I use it. Other places however are a different story. In this video we will talk about one particular style meter that used to be commonplace in Great Britain and pull it apart to see how it works. Will it work on 120v?Remember to follow me on Twitter at @CelGenStudios to keep up to date on what I am doing and what might be happening in the next video.
