You cannot use 85 ROMs in an 87 and vice-versa.

Many of the early interface module manuals were written before 86/87 models were released and therefor only list the 83/85 ROM model numbers. So, this translates to you will need either ROM 00087-15002 or 00087-15003.

However, and this may be a big however, on the HP-85, that ROM contains both PRINTER and PLOTTER support. On the HP-86/87, PRINTER support is built-in, so advice to add the PRINTER/PLOTTER ROM may not apply.

I would guess, from the wording in the IL Interface manual, that the needed support for this interface is built-in to your 86/87 and additional ROMs are not needed for printing. Likewise, you probably would need to add to add the PLOTTER ROM for HP-IL plotting.

Thanks very much, Bob, for this information. At least I can give it a try without adding any ROMs to start and see how it goes. That's a good point about the plotting - probably will need to be aware of that, too.

Thanks!
