I got a mail back from the buyer :
"That is a bit frustrating. Glad they got back to you OK, but I for the life of me could not get them to work on my Microbotics 1230XA. Worrying it was the card was why I tried all the SIMMS I have in it (some are single sided, some are double), but it always boots fine with my 8, 16 and 32MB SIMMS installed. The moment I inserted either of the two 128MB SIMMS, either it refuses to boot at all (no early boot menu), or it crashed whilst loading WB reset, and repeated. I even thought that the non booting of WB could be related to the board not autoconfiguring (even though I have KS3.1) so I used the SetXA util to make sure it was all done correctly, but this made no difference at all.
As the MBX1230 is the only accelerator card I have for my 1200 (I replaced it with a CSPPC when I upgraded my original 1200 to a Micronik Tower + Z3 busboard), I couldn't try it in anything else.
I have recently purchased a BPPC and BV which I am waiting for delivery on, which should also work with the 128MB SIMMS. If possible, can you try the SIMMS in your MBX1230XA board just to see if it is something odd with those modules and that make of accelerator. I do have a 68882 FPU fitted to my MBX board if that makes any difference at all.
If they still work for you with the MBX1230XA as well, I'll take them back and try them in the BPPC once it arrives."
Fact is that I shall send him two other modules, I was planning on doing that from the beginning, but it still keeps on worrying me that other Simms do work in his card and the 128 Mb does not but has no problem in my own Blizzard :madashell:
wurzel : I have tried to search for single sided 128 Mb EDO modules but the only ones I could find turned out to be Dimm´s and not Simm´s as they both are called EDO but definitely not both 72 pins ...
