Texas Instruments Floppy Disk Controller ROM (EPROM) upgrade
This upgrade kit for the standard TI disk controller card allows 80 track drives to be used, such as a 3 1/2″ 80 track floppy.
The modified code supports 40 and 80 tracks for SSSD and 80 tracks for DSSD, whatever drive is designated as the 40 track drive, either #1 or #3, supports 40 track DSDD.
The update is very simple to make, you have to remove the original ROMS and replace with two sockets and insert the two 2532 EPROMS pre-programmed.
