Fidelity Elite A/S series hardware (EAS, EAG, PC)
see fidel_eag68k.cpp for 68000-based EAG hardware

TODO:
- add feas (original program)

BTANB:
- feasglab locks up at boot if it was powered off in the middle of the game.
  To resolve this, hold the Game Control button while booting to clear nvram.
  The ROM dump was verified from 2 chesscomputers.

*******************************************************************************

Elite A/S Challenger (EAS)
---------------------------------
This came out in 1982. 2 program updates were released in 1983 and 1984,
named Budapest and Glasgow, places where Fidelity won chess computer matches.
A/S stands for auto sensory, it's the 1st Fidelity board with magnet sensors.
The magnetic chessboard was licensed from AVE Micro Systems, in fact, the
PC model board is the same one as in AVE's ARB (ave_arb.cpp driver).

hardware overview:
- 8*8 magnet sensors, 11 buttons, 8*(8+1) LEDs + 4*7seg LEDs
- R65C02P4 or R6502BP CPU, default frequency 3MHz*
- 4KB RAM (2*HM6116), 24KB ROM
- TSI S14001A + speech ROM
- I/O with 8255 PPI and bunch of TTL
- module slot and printer port
- PCB label 510-1071A01

*In West Germany, some distributors released it with overclocked CPUs,
advertised as 3.2, 3.6, or 4MHz. Unmodified EAS PCB photos show only a 3MHz XTAL.
Though model EAS-C(Glasgow) had a 4MHz XTAL

A condensator/battery keeps RAM contents alive for a while when powered off.
Note that EAS doesn't have a "new game" button, it is done through game options:
Press GAME CONTROL, then place/lift a piece on D6 to restart, or D8 to reset
with default settings, then press CL.

Prestige Challenger (PC) hardware is very similar. It was released before EAS,
it doesn't have the 8255 PPI, but has more RAM(7*TMM2016P). Some were released at
3.6MHz instead of 4MHz, perhaps due to hardware instability? Opening module PC16 was
included by default, this module is the same as CB16 but at different form factor.

Elite Avant Garde (models 6081,6088,6089) is on similar hardware as EAS.

Fidelity Elite Private Line were EAS/EAG conversions released by Fidelity Deutschland.
The "Elite Privat" was probably for the local market and the "Private Line" for export.
They took out the motherboard and leds and placed them inside a little box separate
from a (ledless) magnetic chessboard. The ROMs were unmodified, that makes them
uninteresting to emulate as separate drivers.
