INFORMATION ON  FIDELITY EXCEL 68000 MACH II C+ L. A.  VERSION MODEL 6097

FIDELITY MACH II is an improvement on the original FIDELITY EXCEL 68000, mainly due to an increased RAM of 144K that comprised of 16K static RAM and 128K dynamic RAM which was used for Hash Tables. The original FIDELITY EXCEL 68000 only had 16K RAM. This resulted in a playing strength increase of around 60 ELO for the MACH II.

TEST TO IDENTIFY THE EXCEL 68000 MACH II VERSION

There were in fact 5 Mach II versions sold:

• Version A
• Version B
• Version C1
• Version C2
• Version L.A.

Larry Kaufman wrote about this in PLY Magazine (2/88) in 1988 and provided a method for you to test the different versions.

FEN: 1B1N4/p2n4/3P1P2/2nk1BP1/P7/N7/K3P2P/1Q6 w - - 0 0

The correct move for the above position is 1. Bxa7 resulting in a mate-in-4.

The different MACH II versions solved this in the following times:

• Version A - Plays 1. e4? after 2 minutes and 20 seconds.
• Version B - Plays correct move after 3 minutes and 35 seconds.
• Version C1 - Plays correct move after 3 minutes and 24 seconds.
• Version C2 - Plays correct move after 5 minutes and 3 seconds.
• Version L.A. - Plays correct move after 5 minutes and 40 seconds.

Although the times differ greatly between the 5 versions of MACH II, it is unlikely that there is much of a strength difference between the versions.

FIDELITY EXCEL 68000 MACH II AMERICAN OPEN L. A.  PROGRAM -  picture taken from box.

The FIDELITY MACH II L. A. version featured here, received its name after attending the 1988 American Open held in Los Angeles, California. Fidelity, Mephisto and Novag entered their strongest machines into this tournament. Mephisto entered the Mondial 68000XL that contained the 1986 World Microcomputer Champion program. Novag entered the Super Expert running at 6 MHz, while Fidelity entered the Mach II, however running on a 68020 processor instead of the later commercially available 68000 processor Mach II. Fidelity scored 28-20 against human opponents who averaged around 2120 in playing strength.  Soon after the tournament Fidelity sold this new Mach II L.A. version with a new sticker proclaiming AMERICAN OPEN L. A. PROGRAM.

Level settings, game controls and all other features remain the same as the original FIDELITY EXCEL 68000.
