Hello Dwight-
Google led me to your discussion with Gilis in the Netherlands a while back
and
I thought you might be able to help with a little problem I have if you were
willing.
I borrowed an iUP-201 from a friend and it seemed to initialize OK. After I
plugged
in a 27128 ROM to see what was in it, the unit froze and now gives a "Power
Supply Failure" display and won't do anything else.
I looked inside to see what the four power supplies were up to and it appears
two
of them turn on with commands from the F27/128 module, and were not doing so.
Hi
I don't have enough information on the insides to help you here.
Maybe Joe Rigdon can help. You'll need to get schematics.
Dwight
The only documentation I have is a Pocket Programmer Reference and it's not
much
help. Do you have any suggestions on how I might troubleshoot this machine
or
at least get some documentation on it?
Thanks for your help...
