My pardons that this reply is a wee bit late, but in case someone else happens upon a free/cheap HP-75... I just picked one on the Bay for US$60 on a whim.

By itself, sure, a desktop clock/calendar is an obvious answer for any programable device with an alpha/numeric display. After a quick look at the owner's manual, it appears you could use the DISP command to make a usable Tetris clone.

If you were willing to invest a few more coins, a PIL-Box to get data to/from a PC/Mac/Linux system is handy, and the PIL-IO adds digital i/o and a serial link to talk to Arduinos, Raspberry Pi's, or any number of other devices that can talk to a computer.
