Some quick questions on fixing up a TU58:
1) Can I plug it straight into a pdp11/23+ CPU with a 10 pin ribbon cable?
2) Can I hook the 10 pin ribbon cable on it into a normal 11/23 or 11/73
bulkhead to get RS232 for hooking up to a PDT11?
3) Can the PDT11 handle anything faster than 2400 baud on the extension
ports? Can it do faster speeds in one direction?
4) Is there any possible use for this thing :-)

on the extension >ports? Can it do faster speeds in one direction? I can't
guarantee
that it can't go faster, but I've done a lot of testing, and haven't
been able to get it to work faster than 2400. Faster than that, and I
get lots of dropped characters. Still, even at 2400 baud, if you use a
TU58 emulator and the large disk DD patch, it can be a convenient way to
have a lot of files available on a PDT, without having to switch
diskettes. -- Lee K. Gleason N5ZMR Control-G Consultants

Kind of makes sense: All of the serial ports go through the 8085 CPU
interface thingie and my guess is that it can do the register emulations
only so quickly.
I have the RX02's on the big 11/83, but it would be nice to see if I can
get this to work again (I remember using it like 35 years ago or so.
Been awhile)
I'll build up a quick 11/23+ system and see if anything works. I think I
have RT11 on an RQDX3 type disk somewhere around here to test with...

(Did RSX11M+ support the TU58?)

Yep, RSX11M and M+ support the TU58. Don't recall exactly what
versions it first appeared in.

New subject: designjet650C user manuals
I have 2 original user manuals for the Designjet 650C titled "Setting up
For Plotting" and "Using the Front Panel." Seems a waste to just pitch
without inquiring here. Especially since since they don't seem to be
readily available (and Bitsavers came up zip).

Hi Steve,
I didn't see a follow-up to this, so if they're still available I'm
happy to have them.
Cheers,
Dan

they're yours. I have two complete sets so one set is getting scanned
at some point and I can send you the PDFs if you want them too. Give
me a shipping address and I'll get them out.
