All: I?m working on adding support in the Altair32 Emulator for directly reading WAV file samples of audio cassettes. Initially, I?m working with the 88-ACR but it should be a snap to modify that code to support the KCS. A WAV sample sent to me by the person who asked me to look into adding this capability is a cassette from 1977 called the MITS Disk Boot Loader. I?ve known this to be usually distributed on PROM, but I guess if you didn?t have a PROM board, the cassette makes sense. I actually have the source and ROM binary already because I use it for the floppy disk support in the Altair32. Anyway, me and a buddy of mine are starting to parse the WAV samples and it would help greatly if we could get a copy of the manual for the DBL. The owner of the tape doesn?t have it. What I?m really looking for is the toggle loader or whatever was used to bring the DBL in from cassette. If anyone has it and would be willing to scan it for me, I?d appreciate it. Thanks!
