Gang - Hats off to Der Mouse for coming up with working code that can convert a wav audio file to data. It imported into simh/altairZ80 via the PTR device and saved onto an mbasic boot disk just fine and so far runs. 22 Years ago I had to massage the TRS/80 basic code to get it to work on MITS 8K basic and thankfully didn't have to do it all over again! A fun adventure game (Altair flavor) saved. --Chuck
