Fidelity Excellence series hardware
(for Excel 68000, see fidel_eag68k.cpp)

TODO:
- granits gives error beeps at start, need to press clear to play.
  Note that this also happens on a real 6080 PCB with this ROM, granits is a modified SC12 PCB though.
  The problem goes away if RAM stays powered-on, but PCB has no indication of NVRAM.
- granits chessboard buttons seem too sensitive (detects input on falling edge if held too long)
- granits has a module slot, is it usable?
- granits overlock + dynamic /2 cpu divider? (like SC12) instead of static /2 divider

Voice Excellence (model 6092)

PCB 1: 510.1117A02, appears to be identical to other "Excellence" boards
CPU: GTE G65SC102P-3, 32 KB PRG ROM: AMI 101-1080A01(IC5), 8192x8 SRAM SRM2264C10(IC6)
2 rows of LEDs on the side: 1*8 green, 1*8 red

PCB 2: 510.1117A01
Speech: TSI S14001A, 32 KB ROM: AMI 101-1081A01(IC2)
Dip Switches set ROM A13 and ROM A14, on the side of the board

ROM A12 is tied to S14001A's A11 (yuck)
ROM A11 is however tied to the CPU's XYZ

RE info by hap, based on PCB photos

Memory map:
-----------
0000-3FFF: 8K RAM (SRM2264)
4000-7FFF: control (R/W)
8000-FFFF: 32K ROM (M27256 compatible)

control (W):
------------
CPU A0-A2 to 3*74259, CPU Dx to D (_C unused)

CPU D0:
- Q4,Q5: led commons
- Q6,Q7,Q2,Q1: 7seg panel digit select
- Q0-Q3: 7442 A0-A3
  + 0-7: led data
  + 0-8: keypad mux
  + 9: buzzer out

CPU D1: (model 6093)
- Q0-Q7: 7seg data

CPU D2: (model 6092)
- Q0-Q5: TSI C0-C5
- Q6: TSI START pin
- Q7: TSI ROM A11

A11 from TSI is tied to TSI ROM A12(!)
TSI ROM A13,A14 are hardwired to the 2 language switches.
Sound comes from the Audio out pin, digital out pins are N/C.

control (R):
------------
CPU A0-A2 to 2*74251, CPU Dx to output

CPU D7 to Y:
- D0-D7: keypad row data

CPU D6 to W: (model 6092, tied to VCC otherwise)
- D0,D1: language switches
- D2-D6: VCC
- D7: TSI BUSY

------------------
One interesting clone of The Excellence is the Computerchess Playmate-2. It was
produced in 1989 by SPS(Bulgaria) and RRR(Riga Radio Factory). The chess program
ROM is identical to Excellence EP12. All internal circuitry is the same, the only
difference is the capacitor driving the 555 for IRQ is 10nf instead of 22nf.

What makes it unique is the addition of a chess clock.

connector pinout from main pcb:
1) 5V
2) GND
3) 74HC259.pin9 (Q4) = Row LED driving
4) 74HC259.pin10 (Q5) = Column LED driving
5) 74HC259.pin12 (Q7) = Bat. Low signal
6) 74HC42.pin4 (Q3) = Col-D/Row-4 -> 'White Move' if D-LED blinks

The extra board has a 7474, a К1016ХЛ1 (RTC, or MCU clock driver), a 4-digit
VFD display, and some buttons for controlling the clock. IRQ frequency is doubled
presumedly for using the blinking led as seconds counter. It only tracks player time,
not of the opponent. And it obviously doesn't show chessmove coordinates either.

Designer 2000 (model 6102)
----------------
8KB RAM(KM6264AL-10), 32KB ROM(AMI 101.1077A01)
Ricoh RP65C02G CPU, 3MHz XTAL
PCB label 510.1129A01
basically same as (Par) Excellence hardware, reskinned board

Designer 2100 (model 6103): exactly same, but running at 5MHz

(Designer 1500 is on 80C50 hardware)
