flemingt Posted August 22, 2020 Author Share Posted August 22, 2020 There is a bit of torque on it all right, it could do with a hook around the board on the left hand side near the cart slot. But it works fine, nothing a bit of cardboard over the top won't fix. Quote Link to comment Share on other sites More sharing options...
flemingt Posted August 22, 2020 Author Share Posted August 22, 2020 Ok, many steps forward and one step back. The good: Picture over svideo looks great. U1MB is running The bad: That damned keyboard, still not working. Back out with the multimeter. Quote Link to comment Share on other sites More sharing options...

Please post the STL here for others. Also if you want I can add it to my Thingiverse post so these are all in one place. Now we need designs for the XE’s. No problem, I'll post them once I'm back in front of a more modern computer. Quote Link to comment Share on other sites More sharing options...
flemingt Posted August 22, 2020 Author Share Posted August 22, 2020 So I've performed a continuity check across all pin combinations with the kB in socket. These pairs have low resistance 2,16 = 1 2,17 = Esc 4,10 = y 6,11 = h 16,17 = unknown I've checked the socket with the kB removed and they're open. I think it might be time to pull the keyboard apart...again! Quote Link to comment Share on other sites More sharing options...
flemingt Posted August 22, 2020 Author Share Posted August 22, 2020 Figured it out! Now it's working! I realised that most of the stuck keys were near screw holes. They were over torqued. So I put everything together slowly and rechecked for shorts at various intervals. Thanks everyone for the help! 1 Quote Link to comment Share on other sites More sharing options...
mdivancic Posted August 22, 2020 Share Posted August 22, 2020 Nice work! Time to update your U1M... 2 Quote Link to comment Share on other sites More sharing options...
flemingt Posted August 22, 2020 Author Share Posted August 22, 2020 thanks! Now to figure that part out. I've a CF card and reader ready to go. I'll format as FAT32 and stick on the firmware files. I understand I can flash it using the side2 cart. For anyone who's interested, here are the files for my upside-down U1MB 600xl bracket. I printed it in under an hour. 50% infill and with no supports. Orientation images are earlier in this thread. Hopefully someone else finds it useful.

flemingt Posted August 23, 2020 Author Share Posted August 23, 2020 Ok, I'm baffled. I've put the firmware atr and Tim files on the CF card. I can get into side2 and launch the flashing program, see the U1MB but no firmware files are listed. Alternatively selecting the atr from side2 and complains about not loading it. Any tips?

flemingt Posted August 23, 2020 Author Share Posted August 23, 2020 (edited) Now when I select firmware.atr it loads missile command?! Definitely something odd happening. It entered the self test menu on reset. I tried something else, mounting the atr in side2. Loading it. It complains about no DOS. Then pressing help & reset to get back into the U1MB menu. Then Q. At which point the flash tool detects the firmware files and it flashed correctly... I now have the new U1MB menu Edited August 23, 2020 by flemingt Update and success Quote Link to comment Share on other sites More sharing options...
flemingt Posted September 20, 2020 Author Share Posted September 20, 2020 Now it's USB powered! As well as a reproduction joystick to top things off. 1 Quote Link to comment Share on other sites More sharing options...

flemingt Posted September 26, 2020 Author Share Posted September 26, 2020 I built up an SIO2USB cable today. It seems to be working fine with executables and floppy images but I haven't had much success with cassette images. I plan on tweaking the Case design once I get some RAL appropriate coloured filament Quote Link to comment Share on other sites More sharing options...
