ECM magazine, I think, (somewhere between summer 1981- early 1983) had a short ZX81 program for producing truth tables in tabular form - so you could input truth conditions and it would then draw tables with the results. I'd love to see that again.
Also Chris Bidmead of ECM had 2 consecutive articles on tachyons at about the same time. I can't imagine ever seeing again a magazine where you could copy out a program on one page and then turn over and read an article about tachyons. Love to read those again.
Never throw anything away.

Welcome to the forum , by the way, Prolog.
You might want to try this site as well, our friends in Germany.
Google translate helps to get an understanding.
I checked the German site - looks like I'm going to need a compiler!
Now I've found my password I can log in and say thank you! A year late but better late than never!
I've also tracked down the E&CMs with the original truth tables I saw in 1982 - so I'll compare with yours and post!
