I still have it, and the printer as well- I have a series of short electrical programs written in basic, and I do use it occasionally to check calculations rather than develop a full fledged model on my laptop.

I have a Radio Shack TRS-80 Pocket Computer and still use it from time to time. Unfortunetly I have lost the manual which contains the BASIC programming language. I program from memory but not always successful.
