Cirtech GS 8 plusRAM woes...

[amotyka <anthony.motyka@gmail.com>]

Hi guys,
I have recently come into posession of a Cirtech GS 8 plusRAM board,
having given up on ever receiving the Sirius ram card I ordered a year
ago... Cirtech was a British company, which is probably why I can't
find much info about it on the net, only photo's, no manuals, and I
believe this was the first 8mb board available for the iigs. The
trouble is, ever since installing it I have been plagued by random
crashes. Replacing the card with my old 4mb AE GS-RAM III makes the
system (almost) impossible to crash. I have read old posts about 8mb
cards causing trouble with DMA and rom 3 machines, but I'm using a rom
1 and the cards installed are reactive micro's Microdrive (not the
turbo version so no DMA), the apple scsi card (not the high-speed
version so again no DMA) with cd drive attached, uthernet card (no DMA
to my knowledge) and a Transwarp clocked at 16mhz. The card checks out
fine with mega memory tester.

I'm going to run some more tests e.g. with the transwarp at a lower
clock and reducing the ram on the board, but would be interested to
hear if anyone else has encountered similar problems with 8mb boards,
or if anyone can give me some more info on this particular card. I
read elsewhere that this card also has a rom disk feature, and in fact
has two rows of header pins which I presume would be used to program
it.

Thanks,

Anthony
