Just picked one of these up, lurking in a SPARCStation 1 case. I gether
it's a SPARC 5 clone board.
It seems to have 30 pin SIMM memory, but also a couple of 72 pin sockets
(both of these and all 16 30 pin sockets are filled).
Anyone able to tell me if there's anything special about the 72 pin
sockets? I'm assuming both types of socket are used as main memory and
this was just done for flexibility, but it'd be nice to know (just in
case the 72 pin ones are for disk cache or something equally strange)
I have one of these boards in the same case, they must have been a popular
upgrade. It's my understanding that you have to install a matched pair of
72 pin parity simms. According the web site (which is now gone), the max RAM
was 128MB (16 x 4MB 30 pin simms, 2 x 32MB 72 pin simms). This is how mine
is configured. They also use the Sun Y serial cable that splits one DB-25 into
A/B serial ports, as well as an external dongle for audio. The other DB-25 is
a parallel port.
It's actually quite a nice board.
