Quantity   Component name
1 × 6502 CPU - either CMOS or NMOS. U2 Main CPU
1 × 6522 VIA - NMOS or CMOS U3 IO Ports and timers
1 × 74HC273 U4 "Output only" register
2 × w27c512 U5 + U18 Main ROM and character ROM. Main ROM can be replaced with SST39SF010 for snappier programming times.
2 × 74HC590 U6 + U7 Video address counter
1 × 74HC32 U18 Glue logic
1 × 74HC14 U1 Reset circuit + buffering
2 × 74HC245 U10 + U11 - Octal Bus Transceiver for NMOS 6502 (Can probably be jumpered if using 65C02 and BE is tied to Ø1 - UNTESTED!)
1 × 74HC109 U12 VSYNC + HSYNC decoding
1 × 74HC04 U14 16 Mhz clock generator + buffer + glue logic
1 × MIC5504-3.3 U15 SOT23-5 3v3 regulator
1 × HM62256 U16 Main RAM + VRAM Static RAM (SRAM)
2 × 74HC00 U17, U21 Glue logic
1 × 74HC161 U19 Clock divider counter - outputs 8, 4, 2(phi0), 1Mhz general purpose clocks.
1 × 74LS165 U20 Video output serializer
1 × 16MHz Crystal Y0 HC49
16 × 100nF Bypass capacitor 0603 footprint
6 × Pullup/down resistors 0805 ~3k for 6522/6502 pullups - R8 and R9 can be higher value but doesn't really matter
4 × Video address select resistors 0805 Must be 2k2 to minimize bus contention
1 × SIP9 Resistor Array for CTRL-LEDs. I used 1k5 ohm RN1
4 × 1uF 0805 Capacitors
2 × 18pF 0805 Capacitors Crystal caps
10 × LED's 0805 I used green for the output register and orange for the power LEDs. The green ones are a bit too bright at 1k5Ohm limiting
1 × Video reset timing cap C19 0805 10nF would probably be a better choice than the 100nF I use now.
1 × 470Ohm 0805 Oscillator resistor R6
1 × 1M Ohm 0805 Oscillator start resistor R5
1 × Video output resistor 300 Ohm
1 × 150k 0805 Reset timing resistor R12
1 × TL3342-footprint SPST Reset button SW1
1 × Lots of breakable 2.54mm male pinheader for every connectino you want LCSC has lots for cheap
1 × 1k-3k Power LED resistors R10+R11 0805
1 × 2.54mm jumpers
1 × PCB Electronic Components / Misc. Electronic Components
1 × nRF24L01+ SMT module (optional)
1 × USB-A female connector (Molex 67643 style) For PS/2 keyboard
1 × Micro USB Connector (SMD, optional) Check Kicad/Gerber for footprint - for 5v power
1 × DSUB-15 a.k.a. VGA-connector A.k.a. DSUB-15-HD_Female_Horizontal_P2.29x2.54mm_EdgePinOffset9.40mm-Mountingholes
1 × 74HC74 U13
