What's needed for a minimal HP-1000 series E/(F?) system?

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!
