A pesky problem with my Model 16 has prompted me to purchase a
replacement machine I saw advertised on the net. It would be nice to
get the old model 16 running so I wouldn't just have a hulk to gather
dust around the house.
I feel sorry for the amount of hair that the local Radio Shack service
people have lost in the machine's 2 previous visits to their shop, so I
appeal to the collective wisdom of the net for some advice on solving
this problem.
The system fails with "BugHlt 68K crashed" after a couple of hours of
operation under Xenix 3.2. The failure will not occur if the machine is
just powered up and left alone running a memory intensive program. Disk
activity is apparently involved, or at least process swapping, implying
that all system memory needs to be exercised and I/O needs to be going
on too.
In the most recent visit to the repair shop, the power supply was
replaced and the technician gave me a hard disk cable he said was in
better shape than mine. The screen image no longer changes in size, so
replacing the power supply was a good idea. It now takes several hours
for the system to crash instead of just 1 hour, which is probably why
the technician thought he'd fixed the system. Also, before the last
visit, the system would spit out lots of errors like "illegal
instruction" or "bus error" when running solid Xenix commands like ls
just before it died. Now the Z80 simply detects 68K death, with no
dying gasps from Xenix.
Thank you for any advice you may offer.
