How about our Dietz MINCAL 523? 19 bit architecture, memory is 20 bits 
with parity. Microprogrammed machine, microcode within normal address 
space, mixed twos-complement and sign-magnitude arithmetic. Completely 
reverse-engineered due to lack of information :-))
8K core memory, microcode and boot loader stored in foil ROMs (similar to 
wire rope ROMs).
