XY11 Manual, Anyone?

[Mattis Lind]

I have in mind to connect a machine to an IBM 1627 (CALCOMP 565) plotter
and then the XY11 which just arrive would fit nicely, I think.

But I cannot seem to find any manual for the XY11. Anyone know of a manual?

The board is rather simple so it should be possible to work out the details
on how to interface it by hand but it would be nice to have the proper
manual.

Then for software I found a diagnostic, XXYAD0 that supposedly should draw
a square and a rectangle.

Anyone know of other drawing software that uses the XY11
