Fighting Golf Board Fix

Initial boots to garbage:

Reseat all socketed chips and now boots to ram error and flipped image:

Replaced and socketed RAM at 9-P:

Rebooted, and still get VRAM error at 9-P.

Did visual inspection of area around 9-P and noticed some damaged traces on the board (in hindsight, should have done this first)

Got out the meter and did continuity tests on all of the traces and found a bad one (red arrow)

Ran a jumper wire to bypass the broken trace:

Booted up and get this screen:

Jumper for test mode was switched on.  Turned it off and...

 

Centuri Eagle Board Repair

 Upon initial boot, no video, no sound.

 

 

Reseated all roms, and got the background starfield to appear but nothing else.

 

Difficult to tell in the picture, but the background starfield is present

 

Reseated the cpu, and did a quick once over on the board.

Noticed the IC (6331-1J)at 6L was hanging out of it's socket, and was pretty mangled.  Replaced the IC.

 

 Success!

 One of the best attract mode messages ever:

Also have a 2nd boardset that needs to be repaired, will come back to that one later, but I suspect the problem with this one lies in this section:

Building a JAMMA test rig from spare parts.

Decided to throw together a quickie JAMMA test rig from parts I had laying around

Not too many details for this, but a few pics below.  Still need to add a few extra buttons for credit and p1/p2 start, along with adding a test and service switch.

Parts List:
Old 15" Dell computer monitror.
Gonbes GBS-8200 CGA/EGA/YUV/RGB To VGA Arcade Game Video Converter.
JAMMA Connector
Old PC switching power supply
Old Speaker/grill
Male DB9 connector x2
Sega Master System GamePad

Getting all the parts together to test:

Throw it into a slapped together wooden box:

Might try to make a different housing for it, but not too concerned.  Doesn't have to look pretty.  Now to get started troubleshooting some old boards.

Hmmm, What's going on here Part 8

Wiring up microswitches to KeyWiz adapter.

Next step, wiring up power, speakers, and install monitor bezel.  Then marquee and cpo.
