Many thanks yet again to the very kind _Bernhard Wulf_, who took time
out of his busy day to save my OD3210 by sending me a special procedures
document which details resetting the NOVRAM and conducting a few
calibration tests after servicing.
Anyone with any Overland tape drive, feel free to email me directly and
I'll send you the .pdf file... but send your thanks to Bernhard.
So, to recap, replacing the battery on my 3210's PWB caused the battery
backed-up non-volatile memories to get scrambled, resulting in an
4x/second flashing ALERT upon after-service POST. Using the special
procedures (not documented in the user manual where they should have
been), I was able to reinitialize the NVRAM contents and recalibrate the
I know for a fact that this same problem has stymied several people
before me, some of whom probably disposed of their perfectly good drives
as a result.
Thanks also go out to Chuck Guzis and Tony Duell for their clues and

I recently acquired the above mentioned terminal in great shape. On power on, it shows a white screen with black characters, all keys work and echo locally.
But when connected to a known good serial cable with a 9600 getty, I get maybe a little gibberish and no more local echo on keystrokes.
Tweaking the baud rate dips has no effect, and possibly of note, the dip for toggling between white on black and black on white has no effect either.
So, looking inside I don't see anything obviously wrong, no blown caps or damaged traces, but there are some unlabeled dip switches on the main board.
Before I go further diagnosing, does anyone know what these switches do, or what their default configuration should be?
Is anyone else operating one of these that could share experiences.
If someone buys this, let me know. I own one of the IST terminals and use it regularily on Plato (Cyber1). Paul Koning provided me with a copy of the binary resident , and I wrote a wrapper to load it into the terminal upon power-up; so that the terminal will speak Plato ASCII protocol to cyber1.org via a serial cable connected to a PC which wraps things in IP over to cyber1.org port 8005.

I have a pretty rare Cycle 5 Sun 1+ System Board upgrade. It replaces
your system board in your Sparcstation 1+ 2 and so forth with a new
board that has a 200mhz CPU on it. This comes with 128MB RAM
installed, the board supports 50 pin SCSI drives and has a CGSIX
Framebuffer Card. Tested working with NeXTSTEP 3.3 and OpenStep 4.2,
along with Solaris 9

I have 1 pallet packed nicely and ready to go that contains qty 27 DEC VT320
terminals and qty 5 LK-201 keyboards. 2 of the keyboards are missing some
keycaps, but they all functioned well enough to use to test external modems
several years ago.
VT320-A2, 2 power on, 2 no power
VT320-B2, qty 1 power on
VT320-C2, qty 13 power on, qty 9 no power
LK201 keyboards, qty 5, 2 of which are missing keycaps.
None of the housings are cracked. All are dirty/yellowed/ink or marker.
Screens may or may not be screen burned.
