Thanks. Checked it out and there's no battery option present on the E,
there appears to be one in the F. Tested the power supply in the F and
it's completely dead. I get ~0.25V on the 5V lines, and 0V on the 12V
lines. I'll put that one on the shelf for a later day...
Don't tell Tony, but I swapped out the main board from the F to the E
and now the 1000E seems to be working... it powers up, the "display"
register counts up to 3 and at that point I'm able to view registers,
and deposit stuff into memory (and call it back later :)).
Now to see if I can get something running on it...
Thanks all for the help!
