Been meaning to upload these for awhile but been distracted ;)

This game is the USA model with the spinning disc.

Pics are in my album in the Photo Gallery (http://www.aussiearcade.com/photopost/showgallery.php?cat=598) but I'll put them in here also.




I'd rate the glass a 9 but there spots of green missing where the display has rubbed against the glass. Pretty common apparently.






Worst of the wear



At some point the back has broken away from the cab and someboay has used angle iron to reattach. Will remove it and fix it properly.



Lower Playfield.







Close up of Acid Damage from battery.


Battery decapped.

Battery removed





Connector J5 and J6 missing


Wires soldered directly to the PCB.

Things to get and do.

Repair boards
Do mods
Fix cab
Repaint the black part of the headbox.
touch up playfield
replace all bulbs
get playfield glass

Things I've bought so far.

6 new bumper caps.
lockdown bar
missing connectors.

Don't think I'll bother clear coating this one. Mylar is ok and pulling it off is a pain.
So far I've neutralised the acid on the CPU board with a 50/50 mix of white vinegar and water then isopropyl alcohol. Just need to get the parts from David_AVD then I can start repairing and testing the PCB.

Nice AK. Should keep you busy for a while!

Good to see it finally. The playfield won't need too much work either.

I will be laying down some new mylar on mine after all the touchy/feely.

Very Nice Travis :)

Should come up a Treat :cool:

Best wishes for the Restore :D

Acetone and toothbush should to the trick on the CPU PCB

I will be ordering some RIOT Chips soon if you need some ?

nice to see the pics!

That battery damage looks not too bad - at least no one else has tried to "fix" it yet, so you're ahead of the game there.

Shame about the soldered to fingers though :( I know can be fixed, but the original problem caused by laziness...

Machine looks in pretty good shape overall.....should come up looking really nice.:cool:

You've got a bit of work to do with the cpu ,but on looks it doesn't seem too bad....although that's easy for me to say cause your the one who has to do it :lol

Thanks Ando :) I have a full spare I pulled off bootleg Qbert PCB's but if I need more I know the man to see ;)

I've ordered the missing connectors from Great Plains Electronics and the other parts I need from David_AVD to do the board work.
My plan of attack is get it up and running first then tackle the cosmetic stuff.

Got my bits off David_AVD today so I decided to work on the power board.


Had a bit of a no power issue when I fixed up the board and tried to turn the machine on for the first time.
I ended up removing both playfields so I could check the 110v wiring. Turned out the main fuse holder was a bit dodgy.


Powerboard all modded up and working :D

Components replaced as per Clays instructions.

Zener diodes at CR7 and CR6
Resistors replaced at R3 and R10
New trim pot installed
Grounding mod done.
I've only connected J1 for testing purposes.


Connected up J3 (48 and 60 volts) and the chaser and backbox lights worked :D


one of the displays is locked on :( no CPU board is even connected.
You can see somebody has socketed the IC's. This board looks a tad different from the others with some extra components.



For a larf I connected the sound board which I've tested on my Q*bert arcade machine. With the jumpers set to demo mode it repeats "Dare you enter the Black Hole" and "Enter the Black Hole"

Next I'm going to check the transistors on the Driver board then tackle the dreaded CPU board.

Love that the BG , must have one of the best effect BG's of all time:cool:
Never played a BH, but sure looks a game I could sink my teeth into:)

I used to play it in the same arcade as Black Knight and Firepower, the 3 of them were lined up together. At the time I played BK the most as it gave the best value for money but I sank a few 20's into BH just to try and get the ball down to the lower playfield

Good work the repairs as always AK

haha yeah right...Still waiting on connectors, a lockdown bar and the disc motor.
I found 2 bad trannies on the Driver board last night but no idea what they did. once looks like its been replaced before @ Q15. the other dead one was Q3. Probably means something is bad on the PF. The manual is no help.
