I think I know why the RPL TETRIS sometimes corrupts memory. I have found that TETRIS needs a binary wordsize of 64 (to be safe). If the binary wordsize is not 64 the game acts as you descirbe corrupting itself and heaven knows what else. The moral is if you want TETRIS on your machine and you play with the wordsize on your calculator alot add the following program to your TETRIS directory and run it instead of TETRIS: << 64 STWS TETRIS >> 'RUNTET' STO Hope this helps!
