I'm not familiar with the 3056DL except that I'm looking at it in an HP brochure I kept from 35+ years ago.  I used the 3421A at work with two or three modules that plugged into the back for relays and digital I/O to control signal routing and control a couple of other in-house-made pieces of equipment in our test setup, in addition to its DMM functions of course.
