Actually, if it is just the A500HD+ and not the turbo 030 accelerator, you
can use standard 1×9 30 pin simms. Thats what I use in my A2000 version
of the series II card. Only the GVP accelerators require their
proprietary simms as far as I know. I use the 1×9 3 chip version (also
robbed from bad systems 🙂 I have 2 4×8 simms for a Mac, but I can't get
them to work in this card. I haven't tried 1×8's, but they should work.
The only difference in 1×8's and 1×9's is a parity chip. Some IBM
compatables can use 1×8's if their CMOS supports disabling memory parity.
In the Amiga, these parity chips are just not used. By the way, some of
the 1×9 simms in by GVP board will give parity errors if installed in an
IBM compatable (Thats why I got them so cheap 🙂 They are actually bad
simms.
If you're interested in fixing broken things for yourself or just want to
get some good deals on simms (with or without bad parity chips), get
access to the FIDONET. Its like a world wide public junk yard if you have
access to the right Echo's (Echo's are to FIDONET what Forums are to
Compuserve). If your interested in FIDONET, let me know. I pretty active
on it now (And I use my Amiga on it, of course :-).
