The roms on my integral are HP-UX V1.0 and uses both pcb's for HP-UX I
suppose they used smaller roms in the first version or HP-UX V1.0 takes more
I removed once the daugtherboard after that the machine wouldn't boot any
more so I placed it back.
As I heared the difference between HP-UX V1.0 and V5.0 is the first is based
on system 3 Unix and the latter on system V Unix.
I'm using a 7958B harddisk for my integral named it 'usr'so it's in the
default search path and useble with C and Basic.

you want the "software engineering ROM", though I'm not
certain since I don't have one. I'd really like to get one and dump
the ROM; then it should be easy to make a clone of it. As I understand
it, it's just an expansion board full of ROMs. I don't know how many
I have an (empty) ROM/EPROM module in my collection (HP82971). It's an
Integral expanison PC with sockets for 16 ROMs/EPROMs, and DIP switched
to set the starting address, ROM type, etc.
There is some software on hpmuseum.net
to burn EPROMs to use in this
module (said software runs on the Integral). I've just never got round to
The HPUS module in my Integral (I think it's V5.0) is clearly designed to
take a daughteroard contianing another 4 ROMs. Was that ever used for
anything, I wonder?
