Hi Eric,
Yes, that looks the one we have, and yes it has the three pen holder. I
found a user guide of the machine, but our left control panel area is
different than that pictured in the user guide. I took some more picts
of the pcb's in the machine. I will post them on our hack42.nl site
later today.
On our machine, the pcb DIL connector from the terminal connector on the
back was loose inside the machine, and it seems ours is wired for
current loop, looking at the settings decal on the inside of the
backplate. How is yours wired? please take a photo of the main pcb with
al the dip switch settings so we can compare, Besides the side
positioned jumper switches, there are also some dials and switches in
other formats on the board. those are also interesting.
I had to put away the calcomp for the time being as we had a fair yesterday.
How many ram chips are on your board. on ours there seems to be two missing.
I'm thinking about a setup to test the socketed 2114 RAM chips based on
a microcontroller with just a simple good or fault indicator.

Hi Simon, Hello to the group,
this weekend I went digging for the Calcomp 1038/1039 manual and
if your plotter looks like this...

...I may have what you need. Drop me a note and I will try to
scan the schematics next week and load them onto my web
page. Did you make any progress with the plotter already?
Best regards,
Erik.
P.S. My plotter is a 1038 which has been upgraded with the
PCI/906 interface but it only has got a single pen holder. Does
your plotter have got three colors?

Hi All,
the 1039 is an interesting plotter I have got a 1038/1039 as well:
There are two
big
PCBs inside - one is for the low level functions (essentally driving
the servos
and
drawing lines using TTL implemented Bresenham) the second one contains
the
computer (68xx based) which is handling the communication.
So for simply moving the pens with the arrow buttons, the computer PCB
may not
be
necessary. Have you tried this?
The computer PCB controls the LEDs and blinking may well indicate a
problem on
the computer PCB - I thinke I have got a set of documentation. But
unfortunately
it is
stored away, but surely I can do a search within the next four weeks
if there is
real interest. I even read out the bipolar PROMs of the processor card
for
safety
some years ago...
