Hi,
OK I have an 8/i, but now I have a lot of questions; first, where the heck
is the serial number on the dumb thing? The top of the main frame seems to
be the listing for the options and serial numbers, i.e. "KW8I 532," "MC8IA
1877," and "KP8I 774." I know this means it has/had another 4K of memory,
the power fail/auto restart, and the RTC. On the back of the main frame, it
has one more serial plate, though it looks like there used to be another
one. It reads "M26 8I L3213." Is there any way to determine the stupid
thing's serial number or is it there or ??? I have reason to believe that
it's a fairly early machine, since it's a Negibus 8/i, and some of the chip
dates are from late '68/early '69. I'd appreciate not being outbid on the 4K
PDP-8 core stack on Ebay, as I need it to have the full 8K that it once had.
Does anyone have any real docs for the beast they could part with? I mean
originals, yes I greatly appreciate highgate, but since I plan to have a
museum at some point, I really do need the real things. Not to mention that
I don't have the equipment to print a D-size drawing (the module utilization
chart). I also need the trim piece for the top of the rack it lives in (the
old black 6'4" style). While I'm at it, I have no manuals for my 11/34A or
my VAX-11/750..

Subject: PDP-8/i Help needed
Hi,

is the serial number on the dumb thing?
The PDP-8/I is not a dumb thing. Quite an advanced low-cost minicomputer for
1968. The serial number is located where all other DEC serial numbers are -
The little steel tag with the model number. The number after it is the
serial number. They only made 4000 units so yours should be somewhere under
that.

Most were negibus, even some of the final units knocked out. They later
produced PDP-8/Is with posibus/posi converters. I haven't found a PDP-8/I
with posibus yet.
BTW: Has anyone ever seen the add-on to use OMNIBUS memory?

I would appreciate it if you would not bid on eBay at all. You rarely pay
for anything and have been kicked off twice for bidding on many items and
never paying. I have had to pay more for an item to outbid you only to find
out you didn't pay for any of the other items you were bidding on. When I
have been outbid by you in the past, the seller has contacted me to see if I
want it as you have never sent the money :-( Bid with your head - not over
it.

It's going to take a while to find original prnts as they only made a few
thousand PDP-8/I minicomputers. Best get the minicomputer running with
highgate prints and wait for a set to surface later. I have learned to be
patient - if you want it you will find it.
