Ethan,
Its one of my favorites. Still looking for the RC25 to fill the hole though. The
console tape drives need to be repaired so it no longer boots. I remember hearing that
someone either tried, or successfully used a PC with a term program to send over the
bootstrap loader.

Cute package, the 11/725. I used to have one (got it right when DEC
interdicted VMS license transfers for one month to attempt to force
buyers of used hardware to purchase new licenses... failed miserably).
It was on loan to a friend's company that was bought out and moved
without notifing me that they were taking my VAX out of state. :-(
I even had the floating point accelerator in it. At the time, it was
my best number cruncher (14 years ago).

I only ever had my hands on the one in my old VAX. They were available
standalone, but pricey.

What's the problem? Rollers turn to goo? Electronic failure?

There is out there a TU-58 emulator for PeeCee. I've seen it and I've always
wanted to put one together, perhaps with a floppy drive so it would be possible
to still swap media, after a fashion. With the things I've been playing with
in the modern hardware arena, I've also contemplated taking the emulator and
sticking a modern CPU in one of these encyclopedia-sized cases I have and
adding a text LCD display on the front and a couple of buttons (though the
joystick port) and building up a virtual tape library. The ultimate
incarnation would be able to hang a _real_ TU-58 off of it and be able to read
and write _real_ tapes as well as act as a cache/jukebox. In that form, it
would make a nice standalone backup device for DECtapeII.
Got a drive I can borrow in a VT103, got hardware, got the RSP spec (Radial
Serial Protocol), got tapes. Don't got time. :-( It's been on my fantasy
project list for ten years and has managed to only move _down_ the priority
list since then. Maybe when I dig that 11/730 out of the storage locker...

Way cool project BUT the display is still in the bubble wrap. Same problem, little
time.

There's been some threads on this topic, even lately. I don't know that
anyone has a stock replacement, but I'd be interested (got a pair of 11/750s,
an 11/730, a VT103 and a couple of HP serial analyzers that use the same
transport mechanism). I haven't fired up any of these lately, but I'd be
surprised if some of them hadn't had the roller turn to goo by now.

Sounds like a very cool project. I have been wanting
to toy with interfacing
an LCD display with a cheapie PC to use as a MP3 player in my car.
It's a common use for them.
The Winamp parallel port <>LCD connection seems
to becoming a bit of a
standard of sorts.
It has. I haven't wired up any parallel interfaces, but I have a couple
flavors of serial interfaced displays - Matrix Orbital (an established de
facto standard in serial LCD command sets) and the B.G. Micro PIC-n-LCD,
a $12 PIC that handles the messy stuff for you.
I even have an LRP package for interfacing an LCD to
my router so you can
watch the IP traffic.
Love to get a URL to that. I run LRP myself, and set them up for friends
with cable modems about every other month.
Way cool project BUT the display is still in the
bubble wrap. Same problem,
little time.
It's all about priorities. I have a set of back burner projects that have been
there for ten plus years, but they are still there (RK11-C restoration, PDP-8/i
re-restoration, TU-58 emulator, Straight-8 cleaning (printer's ink), and such).

If you ever start working on the RK11-C, feel free to
contact me. I have
the printset, and I've worked on mine, so I know what to expect. Having
a KM11 maintenance card helps a lot, BTW.
I'll bet. Somewhere, someone (was it you?) posted a set of directions for
building a KM-11 from modern components. I plan to make one someday, for
both the RK11-C and for diagnosing several RX01 and RX02 drives I have
that aren't up to snuff.
