I've always had memory problems with my
Sparcstation 4/330 and the
stingray is no exception. Suspecting that cold solder joints might be
the root, I resoldered the SIMM connections on this card. Testing shows
this action rendered the card useless. Stingrays being fairly rare, I
offer mine to someone smarter than I am to make it useful again.
Before you give up totally, recheck your work. In particular, check
you've not made any solder bridges (short circuits, of course) between
adjacent pins. It's easy to do that...
