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

[TASP]

Yes, I have an Edu-Calc flyer from 1991.

double module conversion was $30

triple was $55

HP-IL + either a Development, Extended I/O or Plotter was $45

It looks like they had an arrangement with S.O.S. to do the actual work. There was a 1 year warranty too.


I have an Extended Functions + 2 Extended Memory, but I don't recall if I had the S.O.S. conversion, or one of the advertised ones in the PPC Journal.


I don't recall, but I'll keep looking thru my collection, if anyone was doing modules internal to the 41 body itself. Seems like individuals have done some on there own, but I haven't found an advertised service from back then.
