Overview

A chance haul of brand new free 15" CCTV CRT monitors (x5) has sparked my desire to design and build a standardised small MAME cabinet to fit them and to make the design available to anyone who wants to take part.

CRT

  • Audio also! Test speakers on monitor.
    • # Enable audio (loads snd_bcm2835) dtparam=audio=on
    • using aplay to send wavs from Scratch (find in /usr/share/) from the console - sounds fine!

Cabinet

  • hefty chipboard bases and 2x4's as per the big cabinet
  • laser etched outlines where possible
  • laminated panels made to fit quality T-molding

Major purchase BOM
