 This is SciSys's answer to H+G Mephisto modular chesscomputers, but unlike the
 Mephistos, these boards are actual chesscomputers and not an accessory.

 They called the expansion capability "OSA", for "Open Systems Architecture".
 A serial port for linking to a PC, and a parallel port for expansion modules.
 The expansion modules are basically entire chesscomputers, making the whole
 thing combined a 'dual brain' chesscomputer. The embedded chess engine is by
 Julio Kaplan and Craig Barnes, same as the one in SciSys Turbo S-24K.
