Good evening Gentlemen,

Tonights mini-project is repairing a second SFD-1001 which I've had on 
the 'to-do' list for 18 months now. The problem was quickly tracked to a 
failed RIOT chip. As this sits on a daughterboard with the external ROM, 
can any RRIOT chip from a CBM IEEE drive be used as a replacement?

My understanding was that there were other aspects of the chip which 
were mask programmable to determine where the RAM and ROM were located 
in the address space, but were these ever different across the IEEE 
RRIOT chips?
