Harri is right here, I was mixing SunSparc and HP-PARisk architectures. The
712 memory does NOT fit (without a hamer).

Sun Sparc ELC and SunSparcClassic (and similar Sparc 4C architecture?) can
use the same memory modules as 486-PC's. Those are NOT edo ram as in
pentium-pc's, however they do fit... It might not be what Sun tells, it is
wat is currently running at home...

I've tried EDO ram in a SParc Classic but it does not show up. After a short
test (15 minutes power on and try to use it) I experienced no damage on both
processorboard or memory. Then, again: no guarantees...

Now I know where the name "tucows" comes from ;-)

I recal by head (and might be wrong) to have used pc-based memory modules in
a 712/80. There was something with parity (it needs it or it hates it, don't
know).

Try what the bootloader says if you fit it with pc-based memory modules,
that have the same physical lay-out. (edo-ram is a term that comes to mind,
try it or it's predecessor).

I might be totaly wrong here, in those days (a former job) I was using both
SunSparc stations and HP 712 machines.

I don't give any guaranties....

Success

My 715/80 has a memory problem. Perhaps i need new memory.
Which is the right one to buy?

Greets,
    Christian
