Re: HP71B ROM PAC "UDL-71*" by Viewtronics Message #5 Posted by J-F Garnier on 21 Apr 2011, 1:31 p.m., in response to message #4 by Howard Owen
Thanks to John, I was able to have a look at the ROM PAC.
The ROM is mainly made of a large BASIC program that deals with files, the Wand, and HP-IL devices (the well known "HP82164A" interface, but also two unknown HP-IL devices: "KBUSL48" and "DMX1"). I have no idea of the purpose of this program.
If someone is interested, I have the ROM image available on a LIF image file (for Emu71 or for the HP-71B using the PIL-Box/ILPer), with protection removed...
