I have an HP-75D calculator made by HP with the AT&T nameplate. It has the expansion pod with 64K of memory and the modem ports, but the calculator itself only shows 22K free.
I have a 75C with manuals, but I can find no command to merge memory in the pod with that in the calculator. I have tried the port commands to no avail. Does anyone have a clue how to tell if the pod memory is any good and how to use it?
Also, does the calculator come out of the pod?
I picked this up pretty cheap, but I would still like to get the pod going.
Thanks,
Steve
