I haven't had chance to try that yet. I booted it a few times
after I got it, it runs RSX-11M, which I'm not overly familiar
with. Once I knew it basically worked I thought I would give
it a good cleaning and make an inventory of the parts (it has
a TK50 which I want to make sure works before I put tapes in
it). When I get it back up again, I'll look at the clock
again. Thanks for the information.
