Some of you may be aware of my tendency towards vintage Motorola equipment. Well I now have another new odd board to add to the list:
Vintage Thompson T08D MC6809EP Motherboard
I'm aware that it is just a motherboard and yes I don't know if it works. But I took my chances. While working in the industry I knew about the Thompson computers and have always wanted on. I'm not going to pay $500 + shipping to the US so this is my compromise. I know I need a SCART interface, I think I can connect it to my HDMI TVs. The keyboard is going to have to be a hack (arduino and some chips to a PS/2 keyboard). I'm hoping I can get this working and running. Will be an interesting project machine.
PS: The Liebert (MC6803 based HVAC controller)is coming along well. I'm trying The figure out the asm code to take 2 8 bit values (parallel) and merge each on to it's respective bit on Address 0x8000 (Bit 8 -> Serial 1, B7 - Serial 2, bit 6 -> Serial 3, remaining bits are unconfirmed as of yet.) Even disassembly of the original code is bit (pun!) convoluted.
