"ZENROM + 2 Memory Modules" in single X-Memory module

[Ángel Martin]

Surely it was a custom job done by some of the handcrafts of yore, those kind of arrangements were done on demand back then. Another common configuration was X-Functions and X-Memory together, or even the Extended-IO in the HP-IL housing. I think EduCalc offered that as a service too.

Apart from the fact that both items were in the same enclosure there was nothing different to them from the stand-alone items.
