Now using M68EC040 in its place - V11 beeper is too high pitched, related to wrong CPU type too? maybe waitstates or clock divider on I/O access. Currently(May 2020) when compared to the real chesscomputers, to get closer to the actual speed, overclock V10 and V11 to 230%. This can be done by starting MAME with the -cheat option and going to the Slider Controls menu, hold Ctrl and press Right to overclock maincpu. ******************************************************************************* Excel 68000 (model 6094) overview: - 16KB RAM(2*SRM2264C-10 @ U8/U9), 64KB ROM(2*AT27C256-15DC @ U6/U7) - HD68HC000P12 CPU, 12MHz XTAL - PCB label 510-1129A01 - PCB has edge connector for module, but no external slot There's room for 2 SIMMs at U22 and U23, unpopulated in Excel 68000 and Mach III. Mach II has 2*64KB DRAM with a MB1422A DRAM controller @ 25MHz. Mach III has wire mods from U22/U23 to U8/U9(2*8KB + 2*32KB piggybacked). Mach IV has 2*256KB DRAM, and a daughterboard(510.1123B01) for the 68020 + 32KB RAM. I/O is via TTL, overall very similar to EAG. fex68km4 continuously tests RAM at boot and displays "512", this is normal. To start, hold New Game or Clear. ******************************************************************************* Elite Avant Garde (EAG, model 6114) ----------------------------------- There are 5 versions of model 6114(V1 to V5): V1: 128KB DRAM, no EEPROM V2: 128KB DRAM V3: 512KB DRAM V4: 1MB DRAM V5: 128KB+16KB DRAM, dual-CPU! (2*68K @ 16MHz) V6-V11 are on model 6117. Older 1986 model 6081/6088/6089 uses a 6502 CPU. Hardware info: -------------- - MC68HC000P12F 16MHz CPU, 16MHz XTAL - MB1422A DRAM Controller, 25MHz XTAL near, 4 DRAM slots (V2: slot 2 & 3 64KB, V3: slot 2 & 3 256KB) - 2*27C512 64KB EPROM, 2*KM6264AL-10 8KB SRAM, 2*AT28C64X 8KB EEPROM - OKI M82C51A-2 USART, 4.9152MHz XTAL - other special: magnet sensors, external module slot, serial port IRQ source is a 4,9152MHz quartz crystal (Y3) connected to a 74HC4060 (U8, ripple counter/divider). From Q13 output (counter=8192) we obtain the IRQ signal applied to IPL1 of 68000 (pin 24) 4,9152 MHz / 8192 = 600 Hz. The module slot pinout is different from SCC series. The data on those appears to be compatible with EAG though and will load fine with an adapter. The USART allows for a serial connection between the chess computer and another device, for example a PC. Fidelity released a DOS tool called EAGLINK which featured PC printer support, complete I/O control, detailed information while the program is 'thinking', etc. Memory map: (of what is known) ----------- 000000-01FFFF: 128KB ROM 104000-107FFF: 16KB SRAM 200000-2FFFFF: hashtable DRAM (max. 1MB) 300000-30000F W hi d0: NE591: 7seg data 300000-30000F W lo d0: NE591: LED data 300000-30000F R lo d7: 74259: keypad rows 0-7 400000-400007 W lo d0: 74259,74145/7442: led/keypad mux, buzzer out 400000-4?????

Built-in factory test proves that this program is a V10.

PCB is marked: "CHESS HW DESIGN COPYRIGHT 22-10-2002: REVA03 510.1136A01/510.1144B01 COMPONENT SIDE" There are two versions of this, one with a 66MHz CPU, one with a 72MHz CPU.
