  1. Hi Jeremy: It happens :) That's right, pulling out the power/USB will do. Always restart MIOS Studio following a power cycle. Looks like the current one, yep! Yes, you need to jumper it, means opening up the case unfortunately. Also ensure that resistors R101/R102 are installed. Hope you can get back to the bootloader! If not, it's typically no biggie to reflash with ST-LINK or JTAG. Best, Andy

  2. Hi Jeremy, The cables are the issue 90% of the time :) But what you see there is two columns not driving, so that could also be on the resistor networks (particularly RN5, pin12/13) and other shift registers (particularly IC20, pin 3/4). The other two LEDs on the first 16*8 row are not simple to explain as the other rows and columns are functional. Best, Andy

  3. Yeah this is a brilliant summary. No, it isn't too late to build, so long as the PCBs are still available which is the main thing. Everything is still available and the MOS chips are getting harder to find, so I turned to ARMSIDs. (it took me 2.5 years to build, in spurts, on-and-off). Be warned it is a big project with lots of soldering to do - not that hard, just tedious, but other way to look at it is that it's all practice, practice, practice! @dwestbury, do you have a link to a complete schematic? I'm in need of one since today I finally finished the last bits of this,

  4. Great help by @dwestbury, thanks For SID I bought an ARM2SID pair as SID replacement

  5. Hi dwestbury and listen202 Thanks a million for sharing this! Looks like I can finally finish my build which was stalling so far since I could not figure out how to get Fusion360 to create a proper Toolpath for the Graphics with a cheap 3018 CNC machine. I have only done simple pcb's so far with FlatCAM. I tried to follow your instructions and created a Kicad project. I did not know how to size properly so I went with Listen202's version which seems to be correctly sized. If I measure in Kicad it is (232,41 mm x 163,27 mm). I also had problems with the copper rectangles, as Kicad alw
