Hi, list,
My VT220 went crazy yestoday. When I was doing something else on my
PC, suddenly the VT220 monitor was blank (black) and the LEDs on the
monitor flashed. The frequency was about 4 or 5 times a second. The
keyboard LEDs (LK201) flashed the same speed as the monitor LED.
Taking off the keyboard and the RS232 port did not solve the problem.
Does anybody know what happened? Is there an easy way to fix the
problem? Thanks.

Re: " Were machine-pin sockets even _available_ when some of the early
machines were produced?"
Yes; Augat sockets were available in 1976 for sure, if not earlier.

This is the at top of my list. It's going to be a USB-2 channel
driver (talks to peripherals). Have the design done but have't
started building it. Immediate goal is testing of channel interfaced
devices to help cull the collection of big iron, secondary goal is
operation of the devices from Hercules.
Speaking of USB-to-X interfaces, where X is pecular, thanks, Sellam
for the plug for my USB-to-Documation interface. I'm thinking of
building two more copies, another for me and another for the museum.
Is anyone else interested in one? If so I'll do up a PC board instead
of wire-wrapping, and we can share the production cost. Let me
know by private email.
PS - APL\1130 was mentioned recently. We have the source
on punched cards. I've read it in but there were a couple of errors
which is why it's not published on ibm1130.org yet. Also, it appears
to have been modified (slightly) to run on the IBM 1800.

Don't know much about these things, but Jerry has one in Kent. I know
that they take SSP O/S and 3270? Twinax terminals, but I'm fishing for
more information. Is this like the AS/400, where if it doesn't come
with an OS and firmware disk it's toast, or is it a bit more forgiving?
What sort of drives does it take? (ST-506, ESDI, proprietary?) Is it
220v only? any other weirdness? (Full disclosure- my only experience
with "real IBMs" is the RS/6000)

I got this in an E-mail and it was just too good not to pass on!

Well, I have the 680(b) all disassembled now. I noticed a few things
while I was taking this apart. Since the logo silkscreen is gone, I'm still
trying to determine the model of this machine. My brother was trying some
modifications that I didn't know about back then. So I have to try to revert the
machine back to it's original state. The serial plate didn't survive the
fossilization over the years(it's gone), so I can't determine what
serial number for this. I still couldn't determine if this was a 680 or
680b from the looking at the manual. When I was looking online, I found
some references to S-100 boards that supposedly were made to plug into
the 680b. But there's no place to plug in S-100 boards in this version
that I have.

One thing I noticed after I took this part, the mainboard actually says
this
MITS 1976
680 MAINBOARD REV 1-6x
I hope somebody might be able to help identify this model. I'm thinking
this is actually a 680 and not a 680b, am I right ?

I just looked in the DEC Computer Lab Workbook and it says Copyright 1968.

built a box to go from a channel to a pc (mid 90's)
I have the external box, there apparently was a card as well with a 37
pin
connector that went in the pc
they used TI 751730 interface chips
DEC built 6' rack sized interfaces for the 10 and 11 to talk to a
channel in the 70's
(the DX-10 and DX-11)
