COLLECTIBLE MicroSolutions CompatiCard I PC XT 8-bit ISA Floppy Controller 87-89.

This is a very rare controller and highly sought after.

The CompatiCard is a versatile floppy disk controller card for the IBM PC, XT, AT, and compatibles. The CompatiCard can be used as a direct replacement for the IBM PC/XT floppy disk controller. It also allows the use of a 5.25 inch drive (360KB, 800KB, or 1.2MB in any PC, XT, or AT), and possibly other computers. For use with 8" Floppy Disk Drives, you will need a drive cable adapter. You can make an adapter cable yourself with some basic ribbon cable and a little work.

List of features (from the manual):

• This is a half-size direct replacement for the IBM PC and XT floppy disk controller.
• Supports 8" drives (but requires Uniform-PC for CP/M diskettes).
• Supports both single and double density on all types of drives.
• Support up to 4 drives.
• Drives can be any combination of 5.25 inch (48 TPI, 96 TIP, or high capacity AT), 8 inch and 3.5 inch.
• Up to 4 CompatiCards can be installed in a computer to support up to 16 floppy drives.
• Can be used in computers that already have a built-in disk controller.
• Supports 4 internally mounted drives or two internal and 2 external drives.

This item is being sold as a COLLECTIBLE!!!

Item may or may not work -- I have no way of testing the card. However it was working when pulled from my SWAN XT-10 years and years ago. The card is in good physical shape and has been stored in an anti-static bag all these years.

If you have any questions, please ask.
