1 × WDC65c02s Modern 6502 made by Western Design Centre, runs up to 14MHz
1 × TMS9918a Texas Instruments VDP found in the TI99/4a and MSX computers (the 'a' variant)
1 × Micro-SD breakout board by hobbyelectronics Small board with a micro SD slot and SPI pins that can be bit banged through a 6522
1 × W27c512 EEPROM EEPROM - anachronistic for an 80s computer, but essential for productivity!
1 × 128KB SRAM (628128) - For main RAM SRAM is anachronistic for an 80s computer, but DRAM was going to be too painful
1 × 32KB SRAM (62256) - For video RAM Needed by the TMS9918/9928 - but extra logic needed as these chips expect DRAM
2 × WDC 65c22 VIA Two VIAs made by WDC providing I/O for sound, joystick, keyboard, sd-card SPI
1 × 74XX series logic Various decoders, NAND, NOT, NOR for memory decode / chip select
1 × AY-3-8910 3 channels of sound plus I/O for joystick. Same sound as in Oric-1 and MSX
1 × CMD 65c51 ACIA ACIA for reliable serial comms - no more bit banging through a CIA!
