About the P8x regbank card PCB
P8x regbank card is an open source PCB design by ksr, published on GitHub. It is a 4-layer board measuring 280 × 140 mm, with 95 components from 16 distinct parts.
Other key parts include the 74HCT169, 74HCT244, 74HCT257, 74HCT138 and 74HCT139. By type, the board carries 44 ICs, 44 capacitors, 3 LEDs, 2 resistors and 1 connector.
From the project
Generated by generators/genkicad.py from the canonical geneagle netlist (CARDS["regbank-card"]), same standard as the memory card: 4-layer (F/B signals, In1=GND, In2=VCC planes), a bypass cap above each IC, a labelled LED/jumper bank, part values on silk. Routed with Freerouting.
