Easy TRS-80 M100 (and NEC PC-8201a) factory RS-232 mod 40 years late! Hey Birt! 2023-02-18 | Video sponsor: PCBWay: $5 for 2-layer PCBs with 24hr turnaround at pcbway.comIn this video we take a look at an official TRS-80 Model 100 factory modification that was done to the RS-232 port. This was released as TSB 100-001 almost 40 years ago. The early M100s had too large a currently limiting resistor in the RS-232 output lines which caused compatibility problems with some other TRS-80 products as well as other RS-232 devices. We discover what the problem is, we apply the modification as per the bulletin, and test the results to see how it performs. We also find this same modification also applies to the NEC-8201a which uses the exact same RS-232 circuit design and has the same problem. Timeline:00:00 – Welcome02:46 – Problem demonstration and source10:48 – Fixing the problem16:32 – Testing our fix18:17 – It works for the NEC PC-8201a too!18:50 – Wrap up.

Universal Backpack Drive Hey Birt! 2024-08-10 | In this video we take a look at the newest member of the Backpack family, the ‘Universal Backpack Drive’. A newer version of the same microcontroller family was selected to allow both branches of firmware Epson + everything else to be merged into one ‘Universal’ firmware. Some design changes were also made to simplify construction and allow us to stay with the same low price.Please consider clicking on the Subscribe button below and then click the bell icon.

CE-158X Intro – A modern serial / parallel interface for Sharp PC-1500[A], PC-1600, TRS-80 PC-2 Hey Birt! 2024-04-02 | In this video we take a look at the CE-158X, a modern serial / parallel interface for the Sharp PC-1500[A], PC-1600 computers. The original Sharp CE-158 interfaces are rare, expensive and limited to 2400bps. We created the CE-158X as a modern higher speed replacement. With a solid transfer speed of 19200bps and an experimental 38400bps it takes far less time to transfer programs. We also incorporated a second serial port with a USB interface and the parallel port is now bidirectional. Join us and find out more about the CE-158X.Timeline:00:00 – Introduction00:35 – Overview, battery installation, How to Connect05:56 – How to use, loading files, using parallel port16:57 – Using USB serial port, How to disconnectPlease consider clicking on the Subscribe button below and then click the bell icon.

Alps Y Axis Gears Test 1 Hey Birt! 2023-07-20 | A quick test of a newly printed Y-Axis, anti-backlash, gearset for the Alps printer mechanisms. I mentioned in the video that the fitment between two gears was too tight and prevented offsetting for the proper anti-backlash effect. Turns out it was operator error; I was trying to rotate the inner gear the wrong direction. Silly me.
Sharp CE-158X ‘EXTREME’. Long-term project – building the tools to then build the project. Hey Birt! 2023-07-01 | Video sponsor: PCBWay: $5 for 2 layer PCBs with 24hr turnaround at pcbway.com/g/m3hn11 In this video we take a look at the CE-158X ‘EXTREME’, a more modern and improved RS232/LPT/USB interface for the Sharp PC-1500. This project has taken a few years to first build the tooling: Assembler, disassembler, processor simulator, library file generator. Thanks to a friend who created a PC-1500 simulator in hardware as well as the actual CE-158X the project really took off.

Vintage Document Preservation: Imaging HW, Editing SW, PDF creation. Featuring CZUR ET24 Pro Hey Birt! 2023-05-13 | In this video we’ll explore both the hardware and software used to image and preserve vintage computer documentation. The first step of course is scanning or imaging the documentation. We’ll briefly talk about flatbed scanners but concentrate on using the CZUR ET 24 Pro as I recently got one.Once the imaging is done, we’ll use various free software packages to edit the images and create a searchable PDF thanks to OCR (Optical Character Recognition).

Backpack Trip #1. uSD storage for vintage portable computers. Basic operation and CLI introduction. Hey Birt! 2023-04-01 | Video sponsor: PCBWay: $5 for 2 layer PCBs with 24hr turnaround at pcbway.comIn this video we’ll follow on from the Backpack Quick Start. We’ll cover the differences in the newer Backpack Drive Plus (BPD+), and discuss the file layout on GitHub for both versions. We will also find out how to discover if the .BA programs for your M100 are really .DO, what problems this causes and how to avoid them. We will learn how to change the operating mode for machines covered in standard firmware, how to update firmware including updating to the special Epson version. We will then take a look at the adapters that are available to connect the Backpack with your computer. In an upcoming episode we’ll go into more advanced Backpack topics such as transferring files using XMODEM, writing BASIC programs to access Backpack feature and connecting the BPD to your PC and accessing it through VirtualT.Timeline:00:00 – Welcome01:01 – Differences between BPD and BPD+04:28 – The users manual, GitHub page and product page05:09 – Model T computers: How to tell if .BA files are really .DO10:10 – CLI basics17:30 – Adapters for other computers, wrap upPlease consider clicking on the Subscribe button below and then click the bell icon.

Dodgy Bodgy? A very hungry TRS-80 26-3612, RS-232 Interface (Sharp CE-158) Hey Birt! 2022-12-31 | Video sponsor: PCBWay: $5 for 2 layer PCBs with 24hr turnaround at pcbway.comIn this video we take a look at a TRS-80 26-3612 RS-232 interface for the PC-2. It appeared to be a NIB find but does not work. When trying to power on it has excessive current draw. The fix was accidental and surprising leading to discovering a very odd factory mod. I still have no idea what this factory mod was for.Timeline:00:00 – Welcome01:37 – Problem description and demonstration06:00 – Research and DC-DC convertor secondary testing08:11 – Testing primary side of DC-DC convertor.

A TRS-80 Model 200 that does not know when to quit, or start again. Hey Birt! 2022-12-24 | Video sponsor: PCBWay: $5 for 2 layer PCBs with 24hr turnaround at pcbway.comIn this video we take a look at a Model 200 with an interesting problem. It turns itself on and you can’t turn it off. Once off you can’t turn it back on again. This was an interesting problem, and I get thrown off track a bit at first. We get there in the end with a very simple solution.Timeline:00:00 – Welcome01:21 – Problem demo and research03:27 – Teardown, temporary power switch and false hope09:42 – New switch, same problem!16:53 – Wrap up.
