Sadly no, there does not seem to be any EPROMS inside these machines. Or anything else inside them that can be hacked by an owner, apart from the crystals themselves. All these machines these days now seem to use the "Black Blob" CPU which presumably includes the program itself. Gone are the days where the Novag machines had chips per se. Even the Star Ruby has one of these "Black Blob" CPUs / ROM.

I have even written to Novag suggesting that if they release new programs in the future, that they consider adapting the much older 16K programs which played a far superior game. The old VIP, for example, ran on a 6301Y and was stronger than the original Constellation.

I wonder if Novag still have those older Kittinger programs such as Constellation, Primo, VIP, etc!? I would much rather trade the smaller openings libraries for a much stronger program once out of book!
