ARCADE / Can Cabal trackball-version be converted to joystick-version?
« on: September 28, 2011, 07:57:27 AM »
I managed to snap up an original Cabal (TAD-8710 board). Got it cheap, as seller claimed it to be defect (no sprites). But only thing wrong was that the ribbons were fallen out of their sockets; easiest fix ever };-P

Now 'problem' is, that it's the trackball-version, and I don't own any trackballs. Question now is: Can it be converted to joystick-version?

Initially I didn't think so, but then found this on klov:

...When converting from track ball version, please change IC D4701AC (2pcs)
at location C D 1 2, on bottom board with socket plug in adaptor....

When I look at my board it actually contains 2 D4701AC at positions C D 1 2.

So now it comes:
1) Anyone knows anything about this socket plug in adaptor?
2) Anyone have one?
3) Anyone have a diagram so I might build one myself?

Nice one...I love this game. I played it alot down at the grill as a youngster and it actually was the first PCB I ever bought.
It still works perfectly and I play it often.
It's close to impossible to 1CC (never did it myself) because of the totally insane bosses towards the end of the game...
Congrats with that catch };-P

Forca Womble };-D

I remember when I bought my first 1942 I thought that the music was broken.
After finding a youtube of the gameplay I found out that the "music" was suppose to sound like that };-D
Having never tried the arcade original only the C64 port, I was greatly disappointed };-D

Super cool. I also found my 2nd 2p upright at hard-rubbish (inside was a 2 slot MVS); same goes for one of my Namco Arcade Stick for PSX and quite alot of retro consoles };-P

My other upright (my first) was my 10 years anniversary gift from my wife; now THAT'S true love };-D

Never-the-less, the design with the sub board is extremely fragile, as this rep log also shows.

The sub board should be pretty easy to contruct yourself, I could try to make a diagram. Unfortunately, my EPROM-programmer can't read the EPROMS tho.

ARCADE / Turbo Force Repair Log

Now I did do a mock-up of this somewhat easy repair with just some hook-up wires a few months ago, but always had a feeling that it could be done nicer. And now it just bugged me so much, that I had to do it...and why not make a log for others to see, I thought };-D

Got this original Turbo Force as untested in a larger batch of untested boards.

It wouldn't do anything just black screen and no sound.
This construction immediately caught my eye; the sub board had a loose wire hanging from it.

And when I pulled the sub board from it's socket, I saw that the thin bit were broken off of 2 of the pins

and one of the pieces were still stuck i the socket.

I managed to remove that with 2 needles and alot of patience.

Now my first plan was to saw a bit of the 2 broken pins and pacthing them with 2 pins of header strip by soldering them on.

But I must have been too eager when sawing and wiggled the pins too much, cause they broke off at the end soldered to the sub board, also taking the pin beside them in the fall with them };-(
So that plan was out. I then remembered that I had a strip of these from a batch of scraped components I got from a shop once

I straitened 3 of them out and pulled them out of the socket. Cleaned the holes on the sub board, soldered them in, and cut them down to the right lenght.

Now I had to deal with the loose wire. Putting the sub board back in place, the lenght of the wire gave my an obvious radius on the board to investigate. I quickly found a pin on a socketed IC with a blob of solder on it

Tried connecting the board just pressing the wire against this pin, and viola:

Now I soldered the wire on

Case closed.

Actually it's a great vert shmup only using 1 button; smart bombs can be picked up, but are fired immediately upon pick up. The board also have a molex for a 3th controller so you could play 3 players simultaneously; I'd like to have a try at that some day };-P

Btw the hookup wire I used, is not quite thin enough i think.
What do you use for hookups?

I am a young fool. Only now, at the end, do I understand. My feeble skills are no match for the power of the Dark PCBs! I have paid the price for my lack of vision!
I afraid my faith is forever sealed now!

Yes, and a bit dangerous too. Last night I was so ecstatic that "accidently" bought an original Konami Gryzor/Contra };-P

Is this game available in MAME as a bootleg?
As far as I've been able to find, there are two rom sets...none of them matches my ROMs...but haven't dived deeper into it.

Thnx m8! Still totally high and having trouble hitting the keyboard as my arms is still stuck above my head };-P

Have you got any idea as to why I still get the "RAM ERROR" at start-up?
