That sounds about right (taking into account the date typo ;)

I actually have two ARM-based ISA boards though - one calls itself a "PC ARM 
coprocessor" and contains just the CPU, MEMC, DIP IC memory, ROM and TUBE 
chip. The other claims to be a "PC ARM Application Card" and is similar, but 
uses SIMM memory and also contains an IOC + podule backplane.

I'm guessing the former board is a 'Springboard' (I've seen one other PC ARM 
card, and that looked like the former one, too), but I've no idea about the 
latter - if it was also released as a Springboard, or if it was some in-house, 
low-production development board as part of Archimedes development.

cheers
