Fidelity EAS / EAG prototype
Fidelity EAS / EAG prototype
It's a version between EAS Glasgow and EAG, the program is closer to EAG than Glasgow, so I've named it a prototype of EAG in MAME, but it may as well be a prototype of a canceled product.
This board used to be owned by Peter Reckwitz. The EPROM labels have "EXP" (for experimental?) Maybe it was used in a chess computer tournament, who knows.
Quick view of similarities:
EAS G.: 510-1071A01 PCB, 4MHz CPU, 4KB RAM, 1 7seg panel
This: 510-1071B01 PCB, 5MHz CPU (but could have been overclocked by mr. Reckwitz), 16KB RAM, 1 7seg panel
EAG: 510-1071C01 PCB, 5MHz CPU, 16KB RAM, 2 7seg panels
510-1071B01 PCB was manufactured in 1985 by Fidelity Computer Products (Fidelity's company name after "Fidelity Electronics" bankrupcy and before "Fidelity International" formation)
~~~~~~~~~~~~~~~~~~~~~~~~
Right, it is somewhere between EAS and EAG, I was hesitating whether to put it under EAS or EAG.
The PCB and therefore the hardware is more similar to EAG (16KB RAM, different IRQ generation, the faster CPU). The user interface is indeed like EAS. Now that people can experiment with the program, maybe someone can make a new forum thread. Berger can share PCB photos there.
