My AutoCAD 2.18 Installation manual (March 1986) gives serial cabling for Numonics 2200 Series plotters to PC as: Tablet End Computer End 3 -------------------- 3 4 --| 5 --| 7 -------------------- 7 6 --| 20 --| To use with AutoCAD, set the tablet for binary data transmition at 9600 baud, 8 bits, one stop bit. Switch settings are: Switch Open(Down) Closed(Up) Doesn't matter A 2,5,7 1 3,4,6,8 B 5 3 1,2,4,6,7,8 C 1 2,3,4 Lastly, the AutoCAD notes say that the tablet can be configured to emulate other brands by changing the PROM chips.

It appears to be complete (minus manuals - grr!) and supposedly works, but I don't even know what it plugs into and I don't have any driver software for it. (I'm not even sure how old it is :) <snip>
