pu-18

PCB thickness is 1.2mm. To generate production files you should use KiKit.

What's tested working:

  • Power supplies
  • Digital logic (CPU, GPU, RAM, SPU, etc)
  • Composite video output
  • Memory cards/controllers
  • CD subsystem, audio CD playback, loading games etc
  • Parallel port

Not working / known issues:

  • The holes for the lid switch connector are too small, requires grinding the pins down to fit
  • QFP100 footprints do not extend past the legs at all for Sony chips, making it very difficult to solder with an iron; hot air is recommended

Not tested:

  • Serial port

With the currently defined production setup this is the list of components you would have to transplant from a donor board. These are all located in the same spots on a real PU-18 board so they should be easy to match:

  • CN103: PIO port
  • CN104: Serial port
  • CN502: audio/video multiconnector port
  • IC102: BIOS ROM
  • IC103: CPU CXD8606Q
  • IC106, IC107, IC108, IC109: 4x RAM KM48V514BJ or compatible
  • IC201: VRAM D481850DF or compatible
  • IC202: RGB digital to analog MC141685 or compatible
  • IC203: GPU CXD8561BQ
  • IC303: SRAM CXK5V8257BTM or compatible
  • IC304: Mechacon MC68HC05G6
  • IC305: CDROM decoder CXD1815Q
  • IC308: SPU CXD2925Q
  • IC310: SPU-RAM MB814260 or compatible
  • IC402: Audio DAC AK4309A
  • IC501: RGB to composite CXA1645M
  • IC601: Voltage regulator TA78M05F or compatible
  • IC701: CD DSP CXD2545Q
  • IC703: RF amplifier CXA1791N
  • IC704: Motor driver BA6392FP
  • IC706: uPC5023GR
  • RV703: push-pull adjustment pot, or replace with modern TC33X-1-473E and recalibrate
  • S301: CD cover lid switch
  • X101: CPU crystal
  • X201: GPU crystal

Additionally these are included in the BOM but might need to be transplanted if assembly runs out of stock:

  • IC702: opamp NJM2904
  • IC708: opamp NJM2100
