I found several spare switches and handles for what I believe would be a
PDP-11/10 or similar. The handles are white and are marked 1210785.
The switches are C&K 7121 (on-on) and 7128(on-momentary on).
Can anyone confirm?
Thanks,
Kyle
They came standard on the industrial series of monitors from IBM.

Apparently, the stuff is still made:

Perhaps you could swap in a Toshiba 9-inch green monitor from a Kaypro 2 or 4. Seems to have
the same 4-pin connector, and used Kaypros are cheap. There's a standalone CRT on Ebay right
now, including yoke, for $19.99 + exorbitant shipping:

Seeing the discussions about the HP150 and the HP-IL stuff reminded me that I have an HP 150 with the 3COM Ethernet card, but I've never found any software for it. I checked hpmuseum.net and they don't have software, and didn't even have a picture of the card until I provided them some pictures of mine. Does anyone happen to have the software?
Not my auction -- just noticed this:

Apparently includes software and documentation as well, who knows how much
or what it is.
Local pick-up only (in MA), but a nice haul for someone, for a decent
price. I think this was listed last week and didn't sell...

I am not sure about finding a CRT that will find that housing. It is VERY
tight in there and the cables are routed every which way. However, you could
always use the component out with another monitor if you wish. The 5155 uses
a std. CGA video card. I've hooked up a IBM 5144 to it in the past and it
does make for a sharper image.

Under RT-11 and RSTS/E, the KED editor supports the
VT100, the VT52 and the VT62 terminals. DEC produced
9 variants of KED:
Ked.SAV, K52.SAV and K62.SAV for normal RT-11 jobs
under both UnMapped and Mapped RT-11 Monitors although
with a V05.06 Mapped RT-11 Monitor, the cut / paste buffer
is much larger.
Kex.SAV, K5x,SAV and K6x.SAV for RT-11 jobs under
a Mapped Monitor probably expected to be executed as
system jobs.
Ker.SAV, K5r.SAV and K6r.SAV for RSTS/E jobs.
So there is software which is specific for the VT62. Since
I have never had a VT62, I have never used K62.
Because I usually execute under Ersatz-11 which supports
more than 24 line displays (and more than either 80 columns
OR 132 columns), I added code to the VT100 variants to
support the VT420 which supports 48 lines. The executable
files are K42.SAV, K4x.SAV and K4r.SAV, respectively. In
fact, since Ersatz-11 supports up to 255 lines by 255 columns,
K42.SAV also does so, BUT not at the same time (since the
screen buffer would then overflow the available memory).
In practice, even using the Win32 variant of Ersatz-11, the
maximum screen size my video card and monitor are able to
support is 79 lines by 120 columns in narrow mode and
79 lines by 198 columns in wide mode. So there is never
a problem if I stick to those values. The code and data in
K42.SAV have been optimized for use as a background job
under a Mapped RT-11 Monitor when VBGEXE is also
used so that the cut / paste buffer is MUCH larger. In
addition, K42.SAV interrogates the screen size (JUST
ONCE) immediately after the first file name is provided,
so the user can also use a VT100 screen size in addition
to any of the possible sizes which Ersatz-11 can support.
Consequently, no unnecessary characters are wasted on
the screen buffer.

Does anyone out there have the ability to read and image an RP03 disk pack? I have a rare opportunity to recover a rare unix version known as UNIMAX, a hybrid V7/SysV that runs on a 256k 11/34 or /45 system.
Thanks for any help!
Hello,
I have a VAX 4000-100A with possibly faulty firmware, version KA52 V1.3
VMB 2.15.
I would try to upgrade the firmware, I found on Maintenance Documents a
paragraph describing
how to upgrade it, having a ROM image file or a bootable tape.
Anybody has some of it?
Thanks
Andrea
I picked up an RX2620 recently. It came without an internal slimline DVD
drive. I believe it is IDE, but I don't know if the connector is standard
(it doesn't match a connector on a laptop DVD drive I found). I have not
been able to find any parts info for this machine.
What should I be looking for to get a slimline DVD drive for my RX2620?
Regards
Rob
