About the P8x ps2-card PCB

P8x ps2-card is an open source PCB design by ksr, published on GitHub. It is a 4-layer board measuring 280 × 140 mm, with 30 components from 11 distinct parts.

Other key parts include the 74HCT30, 74HCT138, WIN CMP, 74HCT374 and 74HCT244. By type, the board carries 13 ICs, 13 capacitors, 1 connector and 1 resistor.

From the project

Built by the bespoke genps2.py (placement: the two mini-DIN-6 sockets on the bottom edge, the four status LEDs on the right, the bus connector on the left) from the canonical geneagle netlist (CARDS["ps2-card"]: an ATmega1284P behind a 74HCT374/74HCT244 latch bridge), to the same

Built by the bespoke genps2.py (placement: the two mini-DIN-6 sockets on the bottom edge, the four status LEDs on the right, the bus connector on the left) from the canonical geneagle netlist (CARDS["ps2-card"]: an ATmega1284P behind a 74HCT374/74HCT244 latch bridge), to the same standard as the memory card: 4-layer (F/B signals, In1=GND, In2=VCC planes), a bypass cap above each IC, part values on silk. Routed with Freerouting. GENERATORS ARE CANON -- edit genps2.py (or the netlist in geneagle.py) and re-run build.sh here (or generators/build.sh ps2-card).
