Looking for IBM PS/2 or PCjr Speech Adapter Tech Ref

[Michael B. Brutman]

The PCjr Speech Adapter sidecar is rumored to be identical to the PS/2 
version, at least as far as the BIOS support on the adapter goes.

I'd like to play around with mine, but the only programming notes I can 
find are in BASIC using some assembler hidden in some DATA statements. 
If I get really desperate I can extract the relevant code from the DATA 
statements, but I'm hoping somebody has the tech ref.


Thanks,
Mike
