Don,
Thanks for all the info. I just opened it up and the board is marked
"model 1 Rev 1.1. The EPROM says "ROM 1.3" and what looks like "71FB". I
tried to remove the drives and board to get a better look at things but it
needs a very narrow offset screwdriver to get the screws out of the middle
between the two drives so I wasn't able to. Thanks for the info about the
printer port. That could have been a costly mistake!
