This is the only reference I found so far about the presence of the HP-48 series in shuttle flights:

and that, children, is why they take up a pile of HP handheld calculators with them. Used to be the HP41C/CV/CX series, today it’s the HP48SX/GX series. Without going into extended/expanded memory, the older 48SX can hold 288 K of memory. With extended/expanded memory, the new 48GX can hold over 1 M of memory.
