It’s been a couple of months since my last bavacade update. I was under the impression I hadn’t done much since January, but after taking some notes I realized I was mistaken. Real headway was made and I even added a few more items to the to-do list below.
Stuff that is done:
- Pole Position has been put on wheels and that game was re-assembled and is working beautifully in its new home at the bavacade.

- Back-up Scramble board being used in Super Cobra. Key difference is that the Scramble board now has a multi-game kit that allows me to default to Super Cobra at boot-up so that cabinet now has free play. #winning
- Roberto copied Super Cobra ROMs from working board so the back-up board is no longer throwing garbage, soon after realized audio is crapping out. So one board working perfectly and the other has audio issues.

- Tested 440 Dev Kit on non-working Crossbow and it was still throwing garbage. I replaced original chips on board and sent it off to Mike to take a look and he reported it works perfectly, so still confused on this one.

- After testing Crossbow boards to no effect (see above), I disassembled the cabinet and Alberto put it on wheels. Once the boards come back from US will start to re-assemble the cabinet, but also waiting on new molex power connectors given I need to clean-up/replace some of the board connectors that regularly come loose.

- Both the switching power supply and power brick for Make Trax is in for wire clean-up with Roberto (in addition to the Robotron power board and brick). I realized the extra power brick and power supply board I had lying around for Joust will work fine in Robotron –so got that game back up and running.
- Secured the edge connector for yoke wires on Make Trax which needed to have wires inverted for Crush Roller board to work.

- Had Mike repair a Super Break-out board Roberto wanted me to test: (1) Updated LM323K $20; (4) 2102 Ram $24; (1) 7408 $0.

- Ordered a ton of molex and edge connectors that should arrive any day and will help with my general maintenance project to clean or replace as many of the connectors as possible.
- Built a shelf to organize and store all the extra arcade equipment and back-up boards in bavacade.
Things Still To Do:
- Re-assemble Cheyenne.
- Test 19″ tube with a Hanterex Polo chassis connector that Roberto brought me. If it works I might finally have a replacement for dull Phoenix tube.
- The new tube gives re-newed impetus for getting extra Hanterex Polo chassis fixed.
- K4600 back-up chassis slated for repair still in pieces and has not been attended to.
- I messed up the new lock on Pole Position and need to see if I can replace it, that was stupid, also need to add a lock to the lower coin vault door.
- Venture wiring needs to be cleaned up more, considering swapping in the Condor +5V power supply given that’s only voltage the switching power supply in that game is being used for —and this might clean-up the ugly on-board soldering happening now.
