I don't know where hap got this prototype from.
All about this "Victoria" prototype that can not even read library cartridges, is a mystery.
Why is there no opening library with it?
Maybe it came from a module with 6.144 MHz, but this program is made for 6.7 MHz.
No one has seen a photo of it or PCB, unless it's from Steve Blincoe,
but Steve says he wont open his "prototype". (See other forum about this.)

So time goes about 10% to slow for the chess engine,
causing it to think too long time, eventually causing a time forfeit.

Berger also knows how to check the interrupt frequency of the Conchess programs.
