The TRS-80 Model 1 Emulator for PCs, written by Jeff Vavasour, comes with
some utility programs which can read and write TRS-80 tapes using a
Soundblaster-compatible sound card.

You can find a shareware version of the TRS-80 Model 1 emulator at the FTP
site: oak.oakland.edu.  The file is under: simtel/msdos/emulator/model1-d.zip.
I don't remember if the shareware version has the cassette support software;
you may have to register -- it's quite cheap -- to get those utilities.
You'll certainly need to register to get their source code.
