Don,
I am currently looking for an older LA36 which has a 20mA connection (I need
it to connect to my ancient PDP-11s). Do you know the model numbers for the
LA36?
Thanks.

Got an FCC ID number on that board (assuming it was for sale in the US)?

Free + shipping:
DEC VT330 monochrome graphics terminal. Excellent condition, in working
order.
Includes LK201 keyboard, VSXXX mouse, and 3 "preliminary draft" manuals:
- Installing and Using
- Programmer Reference Manual, Vol I: Text Programming
- Programmer Reference Manual, Vol II: Graphics Programming
This was a "field test" unit from the days when I was a beta site for
DEC.
Please reply off-list.

I think that there is some confusion on this part.
First : Mostek wasn't in the TTL business, perse
Second: I'm pretty sure that the part referenced below was a 7449, a
cousin of the 7448.
Thirdly : 7429 is most probably a date code.
From: Tom Kwasniewski
>I cannot find the 7429 in any TTL data books but I have a couple of
dozen
I believe that it's a BCD to 7 segment (LED) decoder with open collector
outputs. Not sure of the pinout, though.
John,
Do you live in Canada? If so, I would be interested in the terminal.
Thanks.

Hi,
Well, it looks like the deadbeat seller who was supposed to be selling
me the HN462532 EPROMs has vanished. He's screwed over another 18 people
besides me and has earned a reputation for ignoring emails. So, I now need
to find another source for some HN462532 or TMS2532 (preferred) or 2732
(I'll need to do some bodging to use these, but still usable) EPROMs. I need
at least two of the same type of device, preferably four (so I've got some
spares). I've got a 10 Euro note/bill/whatever sitting on my desk that I'm
willing to use as payment, or I'll pay in Pounds Sterling. Or Paypal. Your
choice.
It looks like my stupid mistake with the Ace put a -12V spike on one of
the data lines and fried everything on the main MCU bus. That is, address
decoder, secondary decoding, main RAM, CPU and ROMs.
And just when I thought this year couldn't get any worse, my Sansui 210
tuner-amp decided to blow its right aux channel this morning. Although this
is a bit OT, I was wondering if anyone here had a service manual for this
model they could copy for me? Heck, at this point even a schematic would be
useful...
Thanks.

I have 4 DEC LA36 units in various states of disrepair. One appears to be
functioning, apart from the printhead itself, the others probably have
usable components, but I have limited ability to test much beyond the
various motor drives. If anyone needs parts I would be willing to dismantle
and ship for the cost of the freight - which may be the biggest problem as I
am located in Alberta, Canada. Don Woods
It was interesting to look through the archives. Sad, too. Too many
of those computers are familiar!!
Hey, I probably started way back with a Olivetti Underwood Programma
101 (http://www.silab.it/frox/p101). That was one of my first real
experiences with a programmable computer (some would say calculator),
way back in the early 70's.
Somewhere after that I did some programming on a TRS-80, storing my
programs on audio tape.
And I wish I could use my HP-25 calculator (1976). I need to find
replacement rechargeable batteries. It was amazing what one could
program into that thing with only 49 steps locations! Fun stuff and
RPN was interesting.
Blah, blah, blah. PDP-11, DEC-System 10, Apple II in college... so on.
Anyway, cleaning up through my things I've pretty much decided to break
the ties and offer up a few pieces of equipment, if you know of any
interested parties:
------------------------------------------------------------
SUN 3/160 CPU board (pn 501-1208)
Its a 68020 @ 16.67MHz, 68881, Sun-3 MMU, 4MB, 2 MIPS, 9U VME
format, B/W video, Ethernet, serial, parallel ports. This board weighs
nearly 4 pounds!
The site http://www.sunstuff.org/hardware/systems/sun3/sun3/3-160/
claims this is the first 68020-based Sun machine.
------------------------------------------------------------
>From the same 3/160 machine (which years ago I hauled off the 200 some
pounds of chassis-- don't hate me!)...
Clearpoint SNXRAM Memory Board (dated 1986)
Populated with 8MB with sockets for another 4MB, if you have
the necessary 144 MCM6256 (256K x 1bit) memory chips (with an extra
parity bit for every eight, the numbers work out).
------------------------------------------------------------
Maxtor XT 43805 380MB SCSI Disk
Full Height - Approx 6x8x3 5.5 pounds
------------------------------------------------------------
Micropolis 1325 ST506 85MB SCSI Disk
Full Height - Approx 6x8x3 6 pounds
Dated 1986
------------------------------------------------------------
KIM-1 Microcomputer system (late 70s?)
It's a 6502-based micro. According to
http://www.6502.org/oldmicro/buildkim/kim.htm, "The KIM-1 is the first
computer developed by Commodore, or better, MOS [Technologies]. MOS was
an IC producing factory which Commodore took over to be sure of a
constant supply of ICs.... The KIM-1 has 1152 bytes of RAM, 2048 bytes
of ROM and 30 I/O-lines. Some of these lines are used to drive six
7-segment LED-displays and others are used to read the little
hexadecimal keyboard." You would use audio tape for storage and use a
teletype, etc. for My father built this unit up with more memory, nice
power supply, etc.
------------------------------------------------------------
That's about it (I really don't consider old 386 PCs as interesting),
though I do have a Casio FX-7000 graphing scientific calculator (1985).
But I saw on ebay going for $6. Its not about the money, it just
shows there isn't much interest in it.
Thanks for your time. If you know of anyone interested in these
things, let me know (I may keep the KIM-1).

Greetings,
I am trying to find the 20mA connection diagram for a VT50 terminal. The
VT50 is very similar to the VT52, but has a terminal strip on the underside
of the terminal where the 20mA connection is made. I do not know which
terminal is which. If anyone has a schematic of the VT50, I would very much
like a copy.
Thanks.
