Does the
Profile pass the test when running LisaTest?
No, it fails under LisaTest with the same odd symptoms: No sign that it's
even trying to access the disk! Just goes away for a a bit and announces a
fail. I never see the ProFile light flicker.
I'm starting to wonder if Lisa OS has stricter timing or perhaps checks
parity while MacOS does not.
Update: I took the plunge (so to speak) and soaked the motherboard and I/O
board in vinegar for a few hours to neutralize any remaining battery leakage
(had previously cleaned it with PCB flux solvent). This seems to have done
the trick, so there must have been some crud embedded where I could not see
it.
LisaTest is now happy with the ProFile. Onward to system installation (as
soon as I receive some disk copies that are on their way).
I received a known-good set of diskettes for LOS and the various
applications ("tools"). Installation went smoothly and I now have a
fully-functional 7/7 Office System environment.
Next up: Ressurrect the second system.
Finally, does anyone know if there are later copies of
the Profile formatter
EPROM floating around? I have one that works on 5M ProFiles, but the
formatter utility always complains about the version being backlevel. At
least one site on the web shows this procedure with no complaints, so someone
must have it. Would appreciate a copy or leads to anyone who can help.
I was unable to find a later version of the 5M formatter, but I found a
copy of the 10M formatter that a user in Germany had given me some time
back. It is too large for the Z8 piggyback I'd been using. Just picked
up a 4k ROM piggyback Z8 on eBay and will try with that one.
