As a former IBM'er I am glad I retired in 1992

For those of you who have the speech adapter and want a quick way to play back short
messages using the words in the ROM, I enclose a description of how to set up a file
with the words using DEBUG and then play them back from a BAT file or CMD line.

The PCJR Speech Adapter is an interesting device. A long time ago I wrote a program that spoke the first part of Lincoln’s Gettysburg Address using the words contained in the Speech Adapter ROM and for those words not in the ROM I recorded using the mode (CSxx I forget the recording mode name) and w...

Where can I get such software? Also, there's a program for the Tandy 1000 I read about called Penmouse (from a company called War...

This is the only thing I can find that I think pertains to this topic, but isn't much. I think maybe "Chuck" may have put the schematic he developed on the old FTP site that Brian/Mike started. If I recall correctly (not a sure thing) that Brian also had something about it on the old Forum...
