I can help you with the HP tape reader.

I has a simple 10 bit interface, 10 data bits out, a ready flag, and one
step command input. The 'logic' levels are 12 volt transistor drive
signals, active low.

This was used to attach to a special board that plugged into the HP2114
2115, 2116, 2100 and later HP minicomputers (my favorites).
