How to test memory in an HP48 RAM card

[rprosperi]

I thought of another pretty simple thing to try.

Download PCT 5.55/S from hpcalc: https://www.hpcalc.org/details/2456

This is semi-graphical PC-Tools type file manager, which uses port memory extensively, plus it's fast and much easier to use for managing files. The GX version has been around on hpcalc forever, but it took me a long time to find a stable version for 48SX. This one seems to be the final SX version; all later versions were GX only.

Also, contact me off list if you'd like me to do some testing on a GX.
