Hehe, Google helps.  It was discussed 14 years back:

http://comments.gmane.org/gmane.comp.hardware.tandy.coco/562

The specifics of the technique were detailed in Rainbow, June 1990, p.58-64,
where Zumwalt mentioned in passing the Super Program Pak II using 1024K by 8 bit
ROMS or higher!

It latches a 2 (3) bit address by setting $ff40.  But, it eats up the 
entire SCS bank as it does not decode any address lines.
