Now all I need is the CDA, and perhaps some general instructions on how to install a CDA on various bootable media.If you just want a quick way to control the ZipGS, may I suggest "Zippy", a ProDOS 8 SYS program (http://www.fadden.com/dl-apple2/#zippy).
Andy, as I was browsing around your other Apple II stuff on this page, I came across your course on data compression. I'd like to thank you for this course. Quite a few years ago, I found it and the ADPCM algorithm you cited. I converted it to compress 8-bit sounds, and implemented 2:1 compression and decompression routines in 6502 M/L for SOUND.EDITOR. (If your mass storage is a 140KB disk, then 2:1 compression for sounds is a big win-- both in space and in I/O time. ;-) (BTW, the source for these routines is linked on my web page.) -michael Music synthesis for 8-bit Apple II's!
