It's me again, the 2/170 lives on... Anyway, my system has 4 1MB RAM cards installed, and in this configuration, it works acceptably well. A few days ago, I got a 4 MB RAM card with 3 MB installed (1 MB missing). If I stick the card in the first slot the system runs with 7 MB for a little bit, then coughs up a parity error. This occurs regardless of where (in logical counting) the board sits. According to Sun technical support my system is a "non-prime," or old version, and that it was unlikely I would be able to get the card to work. It seems unlikely to me that the card cage is to blame, but if it is, there's probably nothing I can do to fix it. That leaves the CPU board. Would obtaining a new CPU board fix the problem? Is it worth it? If it's not the CPU card, what else could it be? I have an ie0 ethernet board, a tm0 tape board, xy0 disk board and an mti0 terminal board. The ethernet board is not hooked up to a transceiver. While I'm at it, here's a dumb question: If I get a 68020 multibus CPU card can I run 60820 SunOS? (probably not, right?)
