I have a spare 8MB that came from a SUN4/260. Does anyone out there know if this board is usable in a SUN3/160? If it can, do i have to worry about any jumpering other than the external jumpers (above the led's) and the termination resistor? I will be glad to send a summary of replies to whoever asks for one... Thanks in advance George Nassiopoulos nassio@cfa.harvard.edu

The board for a 3/200 series machine is not compatible with a 3/100 based machine. No jumpers or other variables will make it so. As far as I know your 3/200 memory board will only work in 3/200's and will not work in 3/400 or 4/300 either.

I have just tried the combinations below: 3/480, 3/4xx memory Works (of course) 3/280, 3/2xx memory Works (of course) 3/480, 3/2xx memory Works 3/280, 3/4xx memory Works 3/480, Clearpoint 16M for 3/280 Works, but only if it is not the first board in the system. If 1st, it fails the forced ECC interrupt test. Allan Doyle adoyle@bbn.com BBN Systems and Technologies Corporation (617) 873-3398 70 Fawcett Street, Cambridge, MA 02138

We have a few 3/200's that we upgraded to 4's, replacing only the CPU and keeping the same memory boards. They've been running that way for over a year now.

I was under the impression that the 3/400 series used the same memory architecture as the 3/200 and 4/200 - just with a 68030 CPU. The 3/100 and 4/300 series definitely have incompatible memory architectures, though. @alex
