I think due to its age it will support 27256 eprom's the design is from
On the museum site you can find the schematics drawn by Tony.
He reverse engineered the Integral and some modules, the drawing of the
RAM-module explanes the pinout of the memory controller. That should make it
possible to figure out the connections to the eproms.
The software always contains some manual pages.
And I think you have to look for the 'installing peripherals manual' for the
integral HP-UX (V1.0 or V5.0)
