No I didn't know this variant. It seems that it's a pre-production variant still using discrete pulse transformers.

When I started to work on HP-IL in the 80's I got a HP82166 prototype - I don't have it anymore - that was using similar pulse transformers and also had a 32-pin connector. See attached image with the proto side by side with a production unit.

Note that the layout changed in the final HP82166 with the MCU and 1LB3 swapped.
