DEC made the KV8/I option ( http://www.bitsavers.org/pdf/dec/pdp8/pdp8i/DEC-8I-H6MA-D_KV_Graphic_Display_System_Maint_Apr70.pdf) for the PDP-8/I and PDP-8/L. It had a analog function generator which could draw vectors and circles. The board is A312 and is a Dual module. My board look like this: https://svn.so-much-stuff.com/svn/trunk/Eagle/projects/DEC/Axxx/A312/A312Efront.jpg THE KV8 was made for connecting to storage displays like the Tek 611 / VT01 and not displays that need continuous updates.
