Re: OASIS/Jim She's Dead (was Altos "Serie 5" 5-AD Computer)
- there's a good possibility you just need a new ram chip, specifically
the ninth in the series, in fact, the parity chip. Really knowing
nothing about computers or electronics way back when, my Tandy 2000
displayed a "memory parity error" on the screen in the middle of a
chess game. I pulled out the memory daughterboard, which granted was
alot easier then working off the motherboard, and desoldered what I
believed to be the parity chip, soldered in a socket, and plugged a
fresh 4164 or whatever into it. Sho' 'nuff, it came back to life. Had
to learn how to use a desoldering wick and all. And keep in mind, the
best way to desolder something is to add a little solder first.
It could be any of the ram chips though actually I suppose, or another
problem altogether. But I'm guessing it's likely that.
And one day I'm going to invest in a desoldering station. I'd have to
say a must if you're going to be working on this stuph.
