Motherboard from Hell
5 messages in this thread
Well Steve, maybe I kept it too short. I contacted Micron; they directed me
to ASDG (original designers of the memory board) and Progressive
Peripherals (who is now handling the repairs). I contacted Perry K., who
told me to try a 16Mhz 68000. (If I can try it on a trial basis, this is my
next step.) I have two confirmations that the memory board works (on 4.3
and 6.0 motherboards). I have tried a friends ASDG board (the same design)
with no better results. (BTW the board hangs the system during
autoconfigure). I am currently borrowing a CBM board which works fine. The
original flaky boot problem was solved after I replaced the motherboard,
but my memory board stopped working. What I find most aggravating
(disheartening, frustrating) is that I am hearing from other people similar
horror stories about incompatible hardware on 6.X motherboards.
regards (but still frustrated)

Greg:
What I've heard is that SOME of the 68000s in the 6.x run were flaky, and
that replacing them fixes the problem. As I said, that's what I heard. I
do not know if it is a fact.
I do remember seeing some messages here and in some mags (maybe Bug Bytes?)
that gave information on how to tell which ones were flaky by the mfgr name
and number, but I can't remember what to look for. Maybe a lurker will?

I heard the same thing. So I tried a quick test with the 68000 from my
1000. Swapped em and tried it. No change, no better, no worse. I left the
68000s swapped (don't care to do too much swapping of those BIG chips) and
the 1000 is still ok (expanded memory and all). Thanks for the idea though.

So, the motherboard is a 6.0 motherboard? I *think* (maybe someone who
knows for sure will pipe in here) the latest rev is 6.3. Have you tried
the board with that rev?

Steve:
I wish I could, but all I have access to is the 6.2b's (a friend's
actually) and 4.3's(another friend's). The folks at Progressive Peripherals
are the people that have the 6.0. They told me that they ran the board
overnite and ran 43 successful passes of the ASDG memory test. If I can
find a 6.3 motherboard I will certainly give it a try. Thanks .
