This software is my effort to use a zip100 on a tandy 1000.
Works only with early zip drives. Research the difference online.
If this does not work for you try another port, another drive, or redownload.

The media check routine is 'dumb' and returns 1 (same disk) for up to 5 minutes.
This speeds up repetitive directory searches. Press Ctrl C to re-read the disk.
This count can be found at the last two bytes in the file.
hex1554=5460=18.2x60x5=5min. Change at your own risk
