Board game day today

We did play some video games today, with my wife kicking my butt on Millipede.Ouida and I also competed at Tempest, Centipede, Donkey Kong Jr., and Dig Dug.  Here's her and the kids playing some Sorry Sliders:

Other new overlays

And here's three other overlays that were replaced. Here's the panels with the new overlays installed.

New Asteroids Deluxe overlay

We got tired of seeing the CPO on Asteroids DeLuxe all cracked up and in poor shape, so one of my Father's Day presents from the family was an overlay for this game. Here's the process and final result:

Here's the control panel stripped and ready for the new overlay:

Finished product:

Defender - What a pain to keep running!!

This Defender was one that sat in storage for 10+ years, then brought home when the game room was built. Basically 'just' missing the power supply. Put a power supply in and it came up with a RAM error. Replaced the bad RAM and it worked for a few hours. Pretty much had issue after issue since then. Replaced the CPU to ROM ribbon cable, CPI board, 2 ROM sockets, burned misc. ROMs, fixed the sound board, swapped from 4116 to 4164 RAMs, lithium battery mod for settings retention, and for now it has been working for the past few weeks. Hopefully it's the end of problems with this one!!!

Our high score board

Maybe not the most impressive scores in the world, but it keeps things competitive between us. Picked up this black dry erase board from Hobby Lobby for $24 and the fluorescent markers were a few bucks.

Omega Race fixed again

Omega Race worked for a little while, then started rebooting over and over. It would go into self test without issue, but going into game mode would cause watchdogging of the CPU. It would do this after the game warmed up. Probing the RESET NOT signal showed that the watchdog was being cleared as it was supposed to, but I couldn't lock on to a periodic signal with my scope. However, coolant spray, which would normally pinpoint the bad IC, did not work in this case. On occasion, when entering the self test, it would indicate a bad random EPROM. I went ahead and burned a new set of EPROMs and all is somewhat working. The game plays fine, but the screen 'blooms', or enlarges, when warmed up, indicating a bad HV rectifier on the monitor. As for now, at least I get this when the game is powered on, so there is some success.
