Yeah, anybody out there got any printsets, operating manuals or *anything*
for our 730s?

Meanwhile, virtually *no* other additional info has turned up either in my
searches or results of my query to the list of yesterday.

On this particular model of 11/730, both TU58's are side-by-side on the
front. We can compare serial numbers which may, if the numbers make any
chronological sense, tell us which style was earlier (I suspect the
side-by-side was later.)

I'll try to get time to inventory the cards in the crate tonite and pass
the list of M-numbers on to the list. By comparing what-is-where, maybe we
can see if my box is somewhat complete. Input is very welcome from the
others on the list. IIRC, with just a brief look inside, most of the slots
were occupied. Three or four were empty I think.

I'm hopeful the field guide I mentioned in the PDP thread has all these
modules listed. Also, I'm hopeful the machine is complete although I know
the Ethernet controller has been swiped as the ribbon cable from the
connector panel in back is just hanging loose in the crate.

RL01's and -02's, RK07's and a single RA60 are the only drives I have
available. Both RA81's are spoken for I think. The RL01's and RL02's are
not practical from a capacity standpoint to run VMS on the 730 I feel
(*especially* the 5 MB RL01's!)

You mention an R80 drive above. Do you actually mean RA80?

Thanks agian for your valuable input!
