====== SuperQBoard ======
The SuperQBoard was a disk interface card from [[qlwiki: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 two 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 version implemented the floppy using a WD1770 or 1772 floppy controller. 


The third version had tracks that could be optionally populated with components to implement a standard QIMI mouse interface. 


All boards included [[qlwiki:TK2]] on EPROM.


These boards were sold from 1985 to 1987.


Versions one and three are shown in the pictures below.
