Hytype IIs also use a 8 bit TTL based microcoded machine (IICRC they use
74LS283 adders, 74LS170 register file chips, along with bipolar
PROMS)...
I have a few of those boards... Wich I had the correct prints for the
board numbers
I do have. Could be fun to bend them into a general purpose 8bitter.
