That's a major relief, that means I'm not quite as bad off as I'd thought.

Well, I assume that I can't use Q-Bus memory in it? If I could I'd have
some memory. Still needing memory isn't as bad as needing part of the CPU
:^)

I realized this was optional, but it would have been cool to have. What
can I say, I like ethernet :^)

Might have been, I noticed some of the slots had "chips" in them, this
might have been one of them.

Glad to hear this can be pulled that cable has been a pain!

Thanks for the help tonite, while the system isn't as complete as I'd
hoped, at least I now know it isn't quite as hopeless as I'd started to
fear! Looks like I've got to hunt up a couple RL02 disk packs, memory, and
a OS.
