Hi Simon,
thanks for your email and the link to the pictures - you indeed
have a more modern version of the controller. Maybe, yours is the
later OPC907 and not the 906 I have got. Anyhow the plugs look
quite similar, so it probably is a drop in repelacelemt...
My controller understands a subset ot the PCI/907 commands, but this
did nor hurt me as I am only using the very basic pen up / pen down
and goto commands.
The pictures are all I currently have got (at least until my next
visit at my parent's basement ;-))
I think first step is to make the keypads work and than to look
into the controller of the plotter...
Best regards,
Erik.

Hey this is interesting. we have a different controller, indicating that a
change from a 1038 to a 1039 involved changing the controller as well.
see my pics.

unfortunately i cannot find a picture of the back of the controller.

Hi Simon,
thanks for your email. I took the pictures on the weekend and loaded
them onto my server - curious, whether you have got the same setup:

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.
Great, I will check for your pictures and compare... I have got
engineering drawings (i.e. schematics) only for the power supply,
the logic board (sequencer) and the pen driver. Unfortunately the
schematics for the OPC (online plotter controller?) are missing,
i.e. exactly for the interesting PCB with the CPU there are no
schematics at the moment :-(
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?
That looks very crowded as you can see and I do not know whether
this is representative. I guess mine was used in some form of
daisy chain setup but at least the levels are RS232. Yes - I have
been able to plot data on my plotter, but the PCI/906 language
the OPC uses is quite strange and the RS232 is not that easy as it
is using hardware handshake and checks for all signals (RTS/CTS
and DSR/DTR) I think.
I had to put away the calcomp for the time being as we had a fair
yesterday.
Yes, that is quite a heavy machine. Mine is stored at my parent's
basement, so I only have access to the plotter and the documentation
once a month...
Best regards,
Erik.
