Paul -
I have been looking for a clean Amber serial terminal, like the DEC VT320-C2 or HP 900 series,
that I used daily in the early 1990s. There was a common 12” CRT assembly that Ball used (V12) and others. I could probably cross-reference the CRT number.

The Commodore 64 was sold in Canada in Sept. 1982. My brother-in-law bought
his in Toronto around that time. It was $595 cdn.($4,000 today!). A lot of
money back then. Well even today.
Happy computing.
If anyone is interested in anything listed below, or any DEC parts, please
let me know ASAP and I will try to have them tested and loaded for the trip.
SZ12 expansion box
PE32A-BD DEC 3000/300X
PE40A-B9 DEC 3000/400 ( I HAVE TO FIND A CPU FOR IT)
DEC 3000/400?
VAXSTATION 3100/76 SPX
MICROVAX 3100 KA41
3100 DV31CT2-A
VAXSTATION 4000 60
DECSYSTEM 5000/25
3EA 5000/125
5000/133
2EA 5000/200
I have more in another location and will try to find them later today.
I have a lot of extra boards for the above boxes, mostly for the 5000s and
I am still looking for them.
I have VAX CPU and memory boards for the BA23, and the BA213s boxes. Also
"S" box boards and panels.
TONS of Q-bus, Unibus, and some PDP8 boards.
Robins, Rainbows, DECmates, PROs, and parts
Now it gets weird. I have about a dozen or so brand new CRTs for VT330s.
I'm sure they were used in other terminals, but I have no idea which. I
should have all 3 colors.
Also an OMEGA B22, DII and Bessler enlarger and a ton of darkroom
equipment, audio gear including mixers.
Thanks, Paul
Hi

Hi Guys
My DEC Collection needs downsizing.
Im in the UK so for the US only the small stuff would be worth shipping
If you need anything PDP8, PDP11 or VAX please indicate item you
might want

Not exactly the image I'd expect to see on a webpage advertising shiny new technology. It even shows that application running on the VT100 (simulated, but the evidence for that is pretty subtle).
Fun.

Hello again,
Yes, this time I am trying to figure out what I'm doing wrong while
creating a C program.
It is still in RSX11M+ on my 11/23+ and PDP-11 C 1.1.
I have a really simple test program like this:
+>type test.c
#include <stdio.h>
main() {
puts("Hello, world!");
}
The following is what I do to compile and task build:
+>type tstbld.cmd
.IFNINS MAC INS $MAC
.IFNINS TKB INS $TKB
PIP TEST.C/PU,TSTBLD.CMD/PU,TSTTKB.CMD/PU
CCC TEST.C
TKB @TSTTKB.CMD
PIP TEST.OBJ;*/DE
PIP TEST.TSK/PU
+>type tsttkb.cmd
TEST/-FP=TEST,LB:[1,1]CFPURSX.OLB/LB
/
UNITS=1
ASG=TI:1
TASK=...TST
LIBR=FCSFSL:RO
/
The code compiles fine and TKB has no issues. I get my test.tsk:
+>dir test.tsk
Directory DU0:[200,2]
2-SEP-2026 21:36
TEST.TSK;2 22. C 02-SEP-2026 21:30
Total of 22./22. blocks in 1. file
I run it as '+>run test' and I just get the prompt back. I expect it to
print to the terminal.
What am I missing? Nothing stands out to me in the manual. I'm sure it's
something stupid.
Any pointers would be greatly appreciated.

Yes, I did early development on both. At least the interface to the OS was Pascal. I still have the early documentation buried in a box somewhere.

Not my auction etc etc but I believe these are hard to find. Also fits
HP500A and maybe B logic analyser (500C used PS/2).
