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.
