Is there a service manual for Enterprise 64/128?
Somebody know if is usual problems with Dave and/or Nick?
In my Enterprise 128 i know the problem is not with CPU Z80, BIOS, memory expansion, data bus, address bus, power ...
I'm now checking the first 64Kb, but if this memory is ok i don't know how can i check if the problem is with custom chips.
Another question. Do you know if there is some kind of jumper to set memory to 64Kb or 128Kb?
Thanks

Dammit, I've got a ton of Enterprise stuff including factory machinery and
technical documentation as well as unused or returned machines, but out of
all that the one thing I haven't got is a full schematic. The people who
were at Enterprise (or Elan, or Flan or whoever :) I've contacted don't seem
to want to talk about their creation, which is a bloody shame. Then again
times were hard back then, and people were being screwed over on a regular
basis so I can understand, sort of.
Doesn't help me get my prototype hard drive interfaces working though, does
it :o)
Luis, if you need anything from the technical docs I can scan or (hopefully)
photocopy, but it's purely words and no pictures.....
cheers
