RAM modules up to 96k were available and were plugged into the card reader bay.

I have seen 32K and 64K modules by Corvallis MicroTechnology (CMT) and 96K, card-reader port RAM modules by Handheld Products. They are _very_ rare. It took two years before I could find someone who would sell me a 96K module. It is also possible to solder up to 4-5 standard form factor modules inside the HP71 (not recommended for the faint of heart), so that the front ports are left free for ROMS.
