Follow up- What I have learned: There are only 2 versions of the M10 1) M10 - modem (for USA) 2) M10 - no modem (for rest of world)
Each of these has uniquely 1 main ROM, and they are both online. (M10 - USA), (M10-EU) There is a somewhat disassembled listing of the M10 - EU rom on the web ath F.J. Kraan's M10 site. The main ROM from VirtualT comes from this site I believe (because it is exactly 8 bytes too large!). The M10 - no modem PCB uses hardwired jumpers at SW-1 and SW-2 to determine the keyboard mappings. Schematics M10-Modem: findable online at various places. M10-no modem. The destuff and configuration from "modem" to "no modem" are actually not documented but are indicated on the M10-modem schematic. There is a harder to find scan of the M10-no modem schematic, with some hand scribbled modification notes for 128kB RAM upgrade, which DOES show the no-modem specifics. So, that's that. one copper layout 2 schematics, with 4 hardware configs for each keyboard type 2 main roms, with the EU rom containing all the 4 keyboard mappings On Mon, Oct 25, 2021 at 10:03 PM Stephen Adolph <[email protected]> wrote: > 5.
