Several HP products were done this way, including the HPIB version of
the Thinkjet printer.
Also, note that the HP 9807 Integral computer (the 68K/HP-UX lunchbox
computer) has an internal Thinkjet printer which is interface to the
system via an internal HP-IL bus. Too bad they didn't make it available
externally. It's rumored that there was an expansion card to provide an
HP-IL interface, but I've never seen it.
I have (somewhere) the HP specs for HP-IL, and the
1LB3 HPIL interface
chip data sheet
I scanned these for Dave Hick's Museum of HP Calculators CD-ROM set. They
should appear on the next edition which he expects to ship soon.

(heck, although not IL-related, I have the 1LQ4 Saturn
bus
-> JEDEC memory interface chip data sheets somewhere...).
That one I've never seen. Where did you find it?
Oh, and the
HP71 HPIL module IDS (ROM sources, etc for the HP71 HP-IL code). With
those I can generally figure out HPIL problems
These will also appear on a future CD-ROM, along with the HP-71
Software IDS (3 volumes), the HP-71 Hardware IDS, and the
HP-71 Forth/Assembler Software IDS.
The 3421 is
really nice, doubley so both interfaces. You can use it on
The HPIB is a kludge :-). The basic instrument is HPIL, and the HPIB
board is a microcontroller + ROMs + 1LB3 + interface parts. There's a 4
pole changeover switch that links the HPIL port on the main board either
to the external connector or to the HP-IL port on the HPIB card. That
card then translates HPIB commands/data into HPIL ones -- sort of like a
special 82169.
