smaller HP 82166A with 32-pin connector
The technical manual of the HP82166A HP-IL Converter describe a device with a 34-pin GPIO connector. The one I bought is a little bit smaller and with a 32-pin connector. I worked out the pin assignment of this device as good as I can from looking on the pcb.

Has anybody seen this variant of a HP82166A before and maybe can confirm the pin assignment?

Code:
