Game Board #1 Feb 20 2017


  • All game boots to is this screen of blocks.

Troubleshooting/dianosis steps:

  1. Did Fluke 9010a long ROM test of RAM range 0xc000 - 0xcFFF got BTS error 60.
  2. Replaced the MK4027s 2nd and 3rd from left - RAM tests OK now!
  3. Pulled the 16 2708 EPROMS and replace with my Sega/Gremlin Rom Replacement Daughterboard
  4. Game works!
