Calcomp 1039 plotter docs?

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 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.
