Three FAULTY ZX Spectrums and a Diagnostic Cartridge = bad ULA leesmiths workshop 2022-11-12 | Today we are looking at this #zxspectrum diagnostic board and testing it with 3 faulty #sinclair zx spectrums and a nice collection of chips marked as faulty.The Diagnostic card is based on the work of Dylan Smith and you can find more details atgithub.com/brendanalford/zx-diagnostics/wiki/FirmwareYou can buy from myretrostore-uk on ebayThe Diagnostic board has been configured as follows:Page 0 - Dylan's diagnostic 48k ROM v0.1Page 4 - Flash utilityPage 5 - Brendon's diagnostic ROM v0.38Page 6 - Dylan's diagnostic 48k ROM v0.1Page 7 - Dylan's diagnostic 128k ROM v0.1To change the default rom on the card you have to use the firmware util built into the card and that requires a working spectrum. I only covered the first steps and this is how to do the restTo change to boot ROM:Set page jumper to 2-3Plug in cartridgePower on SpectrumEnter command: CLEAR 32767Enter command: OUT 31,36The flash utility will now loadPress enter for other optionsPress x for eraseSelect 0 (Erase page 0)When Done, press any key to exitPress enter for other optionsPress c for copySelect 5 for Brendan's ROM, or 6 for Dylan's 48k ROM or 7 for Dylan's 128k ROM When Done, press any key to exitPress enter for other optionsPress p for programPress 0 (ROM is written to page 0)When Done, press any key to exitPower off Spectrum. Change page jumper to 1-2Power on Spectrum and ROM tests will begin.The version 0.1 rom will test the memory first and then look at the ULA and I think this is useful if the spectrum has no display, but Brendon's diagnostic ROM v0.38 does provide a lot more tests.Music is from the Youtube libraryWill 2 Pwr - half.coolInsta Beat Vixens - half.coolGemini - half.coolhttp://www.breakintoprogram.co.uk00:00 intro00:35 first look at the Diagnostic cartridge02:15 Spectrum with no display just a black screen04:27 running a complete test with a good ULA06:14 Spectrum with what looks like a lower ram fault, but has a new lower ram module09:21 Spectrum with a white screen and border11:42 Testing with the v0.38 diagnostic rom12:33 Testing 4 ULA from a friend marked with X and thought to be faulty.14:33 conclusion

LSW channel update - new workshop and new job leesmiths workshop 2024-08-23 | Hi Everyone, I moved to a smaller workshop because I have a new job, the rent went up at the old space and I thought it was too much money now I am working away so much. I am busy most weekends with 3d printing items for my shop and doing some DJ repairs for my oldest customers. No time for projects for videos and the room still needs a lot of work before I am happy with it.

Powering Sega Master System retro console using UGREEN USB-C chargers and adafruit smart leads. leesmiths workshop 2022-12-09 | #sega #retrogaming #adafruit #ugreen #meanwell This is part 2 of the Sega Master System series and if you remember I had to replace that rubbish cheap PSU that was causing all the interference. At the start I ordered the Mean Well 9v PSU from ebay and I was confident that would be a good choice and also a polarity inverter so it would work on the SMS. Then the same night I was searching I saw the video from LTT Linus Tech Tips talking about this very subject and it was black friday so I ordered the UGreen Nexode charger and the adafruit power delivery USB-C leads. The way this works is the Nexode charger supports power delivery protocols and can be told what voltage to output from the USB-C device like a laptop, but in this case the Adafruit lead has a chip in the lead to tell the PSU to output a set voltage like 9V or 12V. Depending on the specs of your PSU you might have something already just like I had the charger from my Pixel 3A mobile, that only supports 5v and 9v, but it would have made a great choice for the SMS if I decided not to order the Nexode. I will get good use out of that charging my studio equipment so money well spent.If you like what I am doing consider joining my Patreon. patreon.com/leesmithsworkshop Links to the items used in the video , some are amazon affiliate links so it helps the channel if you can use them.replacement switches amzn.to/3Y8WE01USB-C monitor: amzn.to/3VXkbPu5V USB to Barrel Jack: amzn.to/3F9stwRUGreen Nexode 65W charger: amzn.to/3ha2AVOAdafruit USB-C 9v and 12v leads: adafruit.com/product/5449Uk stock shop.pimoroni.com/products/usb-type-c-3-1-pd-to-5-5mm-barrel-jack-cable-1-2m-long-with-e-mark?variant=40092917989459Polarity inverter ebay.co.uk/itm/403950214933?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=gfstdsftrng&sssrc=2047675&ssuid=yBGfqUG9Ti6&widget_ver=artemis&media=COPYMean Well PSU : ebay.co.uk/itm/255386370724?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=UmVBCjmHTXu&sssrc=2047675&ssuid=yBGfqUG9Ti6&widget_ver=artemis&media=COPYTools I useEngineer SS-02 Desolder Pump : amzn.to/3U0dQ4lreplacement tubes for Engineer desolder pump : amzn.to/3i41Q4xMG Chemicals Desolder braid : amzn.to/3i41Q4xAndonstar Microscope : amzn.to/3XsBSInFlux rosin liquid with brush - TK83: amzn.to/3Bibo2N70% IPA in spray bottle -: amzn.to/3P81ztX99% IPA in spray bottle: amzn.to/3Y4XzhV00:00 Intro00:40 Testing the cheap nasty PSU02:10 Testing the Mean Well 9V PSU03:22 Testing with a Pixel 3 USB-C charger and the Adafruit 9v leads.04:30 Testing with the Ugreen PSU04:40 Another look at the Mechanical ZX Spectrum

Connecting old retro keyboards to USB with a cheap Raspberry PI PICO for MiSTerFPGA cores. leesmiths workshop 2022-10-21 | This video was made possible with the support of PCBWAY.....pcbway.comFor a while I wanted to use an actual old keyboard with my MiSTer and design an addon for my wedge case so I decided to look at KMK firmware that a lot of people use for custom mechanical keyboard. KMK and Circuit python was very easy to use and just had to change the examples to work with the small selection of keyboards I had to try. While I was working on this I also found the BBC and Amiga 600 projects , but I was not able to borrow an A600 keyboard for the video.My scripts used.github.com/midicdj1000/RETRO-PICO-KMK-KeyboardsBBC PICO keyboard projectalexparsons.co.uk/connecting-a-bbc-micro-keyboard-to-a-raspberry-picogithub.com/ajparsons/bbc-micro-keyboardAmiga 600 PICO Keyboardgithub.com/thinghacker/Amiga600KeyboardUSBAdapterlinks to pcbway shared filescircuitpython.orggithub.com/KMKfw/kmk_firmwareNoels Amstrad CPC diagnosticsgithub.com/llopis/amstrad-diagnosticsThe connector I used for the Flat flex is a TE Connectivity, Trio-Mate, 6-520315 2.54mm Pitch 16 Way Straight Female FPC ConnectorMusic is from the Youtube LibraryThe Thought of You - TrackTribe00:00 intro01:08 WHY ?02:13 The keyboards I have for this video05:10 Prototypes made on my CNC06:50 Board design 08:07 uploading Gerber to PCBWAY08:49 Looking at the new PCB and some PCBWAY goodies10:32 Soldering Montage11:43 connecting the new PCB to the Keyboards14:00 Programming the PICO with Circuit Python and KMK firmware16:19 How it works21:15 Testing the Keyboards in MiSTer FPGA cores24:15 Final words

Corroded 286 Part 2. Can I fix the CMOS backup and Floppy Drive DMA problems ? leesmiths workshop 2022-08-19 | #retro #dosgames #repair Following on from Ep 1 when I managed to get this MG Headland 286 motherboard to post I continue with the repairs and work on the Keyboard circuit before a lot more testing and some very interesting problems.EP.1 youtu.be/S1IrG-e3O4IIf you want a lot more information look at the tread over at Vogonsvogons.org/viewtopic.php?f=46&t=89208or my github for the LA files.github.com/midicdj1000/headland-286-filesI also tested a sound card that uses DMA and that does not work. Without sound Wolf3d will run for hours with no faults, but once installed a sound card and use DMA it started to get buggy and eventually crash, on top of this no digital sounds worked in any game or in the sound card test programs so the DMA is not limited to Floppy access.Thumbnail is from @JamesOGradyWhatHoSnorkersyoutube.com/c/JamesOGradyWhatHoSnorkersGo and watch his channel if you like retro games especially type in games when he fixes bugs or adds new parts with lots of cosplay, So much fun .00:00 intro00:30 fixing the keyboard circuit02:30 basic testing of the 286 board06:28 trying a Floppy - IDE - Serial card10:17 looking at all the bodge wires15:33 using the Logic Analyzer to look deeper at the Floppy reading problems20:25 A closer look at the LA Data24:13 Testing the Floppy drive and controller on a Pentium.25:41 conclusion - The 286 says NO floppy disc for you.
Mystery 286 PC motherboard with battery damage - will it post ? Part 1 leesmiths workshop 2022-08-04 | #retro #repair #batterydamage #dos I am a sucker for punishment and after the Acid Atari series I bought this faulty 286 motherboard from ebay, but then put it away for a few months because I couldn't face another epic repair. It turned out to be very generic motherboard and hard to find any documentation for it so I had to make do with what ever I could find. This did cause some problems later on, but I didn't stop me from trying to get it working again.Casual Retro Gamer - youtube.com/channel/UC7C0p5DPOBkusUoGf8zIceA/featuredAdrians Digital Basement - youtube.com/c/adriansdigitalbasement00:00 Intro02:42 Initial inspection 07:10 2nd Power on08:08 1 Week Later12:06 New POST card give more information17:01 Keyboard Controller probing19:22 nothing to see, move alongPatreon patreon.com/leesmithsworkshop

This is my DIY Rat Rig Corexy 3d printer with Carbon Fiber EVA 3 parts Episode 1 leesmiths workshop 2022-06-19 | I love #3dprinting and one thing every 3d printing nerd should do is design and build your own #3dprinter. I had lots of parts from old printers and a CNC and decided to take up the challenge. This was January 2022 and 6 months later I am ready to show not just one, but two very fast #corexy 3d printers I made. This part covers the gradual design and build of printer no.1 LeevoRevo, original it was called LeeRonRon (thanks Robee :) ) because I wanted a Voron, but couldn't afford it. Then I upgraded to the E3d Revo and I changed the name to LeevoRevo. Then we build Printer number 2, Boogaloo as in LeevoRevo 2, Electric Boogaloo named by 3DTomorrow. I cover CNC machine work, building the frame and the motion systemThe frame and motion system is from https://www.Ooznest.co.ukThe LDo Orbiter extruder come from https://www.Wedge3d.co.ukLots of parts came from https://www.Aliexpress.comyou can find LDO parts in the uk at onetwo3d.co.ukEVA hot end systems https://main.eva-3d.page/Ratrig pritners ratrig.comVoron Printers vorondesign.comBigtreetech/Biqu for printer boards and drivers https://www.biqu.equipment/Please let me know if you would like more details, I still think it needs more work especially on the Z lengths of the frame so the lead screws do not need to be cut.I have a Patreon if you would like to help me with my crazy ideas patreon.com/leesmithsworkshop00:00 Long introduction talking about the project09:06 CNC machine custom parts13:20 building the frame18:20 Rat Rig Vcore pro motion system22:00 installing the Prusa bed23:40 EVA 3 install24:50 End summery
Sugon-A9 Solder Station - Is this JBC clone worth your money ? leesmiths workshop 2022-05-20 | After a lot of abuse my trusty TS100 stopped working and I can't see the display, It could have been something I did when I changed the case last year. As much as I love the TS100 I thought it was time to get an actual station and after looking at a few videos I decided on the Sugon-A9 from ali expressaliexpress.com/item/1005003762762094.html?channel=twinnerIt has a few options for the type of tips it can take 210 or 245 and I chose the 245 style. You can also select a few tips, but I would recommend just one and then but genuine JBC from a local dealer. You can also buy another handle for the other types of tips if needed.After a few months use I am happy to recommend this soldering station for anyone, beginner to experienced, the range of JBC tips covers just about any job you could imagine.I do have a Patreon if you would like to help and support some of the longer projects I am working on. patreon.com/leesmithsworkshop
