Well, since nobody seems to want those M514400-80R 4Mx1 RAM chips (for Ramfast
cache, GS+ ramcard etc.) I advertised some weeks ago, I put four of them on my
GS+ ramcard, bringing my total system memory up to 7296K. I can't say I've had
any problems. In fact it may have been beneficial for an NDA I wrote in TML
Pascal that tells me sunrise/sunset times. It used to sometimes not work and it
now works perfectly every time. There used to be a problem with the floating
point calculations - they were rounded to integers for some reason. Sometimes
the machine crashed when I invoked the NDA!
The only "problem" I've noticed is that using the memory as a big RAM disk (eg
2048K) won't allow me to boot from the RAM disk - it seems the RAM disk HAS to
be 800K to allow the machine to boot, otherwise you get the sliding apple.
I have 2 more of these chips. Do they have to be mounted in contigious sockets
on the RAM-GS+ card? Unfortunately they are 0.4" pin spacing, so they need a
0.4" -> 0.3" adaptor and I've overlapped the next set of sockets with my
adaptor. But I could put my final pair of chips in the last set of sockets on
the board, to get me the full 8 Megs of ram. Or since I don't really need the
extra ram, one of you lot could buy them for your Ramfast Cache: $5 each and $5
shipping (air mail) to the states...
Adrian.
ps Been playing with KEGS on my Linux box. Pretty good!. I notice the bug in
the Pascal FST is still there (wrong interpretation of the DLE space
compression at the beginning of each line), so it's not just my IIgs at home...
