The SuperQBoard was a disk interface card from Sandy with up to 512K RAM, a centronics parallel printer port and Toolkit 2 on board. The 256K version could be upgraded by a small plug-in RAM card.

There were three revisions of the board. Version 1 had a heatsink by the QL connector, and 256 KB on-board. A 256 KB daughterboard would bring it up to the full compliment of 512 KB. This board implemented a floppy interface by way of a WD1770 floppy controller.

Version 2 deleted the heatsink and carried no memory, using a modified standard 512K Sandy memory expansion as a daughterboard. The deletion of the heatsink often meant that the 7805 voltage regulator could get very hot, but it remained within specification.

This third version had tracks that could be optionally populated with components to implement a standard QIMI mouse interface version and also implemented the floppy using a WD1770 or 1772 floppy controller.

The example in our collection is the third version.

All boards included TK2 on EPROM.

These boards were sold from 1985 to 1987.
