Hi there !

A week ago, i buyed a Sharp Twin Famicom System;
there are a few modifications in the right corner;
Number one is a stereo mod which works very fine...

But there is another port there,
it looks like a Mega Drive / PC Engine RGB Mod...
i think it's for a rgb cable...

The strangest thing is this switch, i have no idea for what it is !
Why should someone add a switch to a Twin Famicom ?


My other problem is that i have made the belt replacement from jfgood's (great page !) and i still get errors like 21 and 22... the belt works fine and the disk system runs smooth.

I have just two Disk Games; Puyo Puyo and a Konami cart, i think its a pirate (there is no nintendo logo on it)

What else can it be ?
The screened Error Messages come really fast on the screen, for me it looks like the disk system gets the error messages before it starts running the engine

thanks for you answer's and sorry for my bad englisch -Uroko

nobody ?

[kite200]

adjust the head and adjust the motor speed for the disk system. we have no clue what the mods do unless you show us the inside of the system

here is the picture of the inside;

i did not get the disk drive back to work...
spindle adjustment and pontiometer have no effect :-( is it possible to replace it with another one ?

[chimyfolkbutter]

Do you have another FDS drive to test your Disks?  You have to systematically narrow down the problem. When I first started repairing drives, I was troubleshooting with a defective disk.   Of course I didn't know it was defective.  I kept getting errors.  When I tested with another disk, the drive worked.  It was working all along.  I learned my lesson.

Start with a good disk.  Then start troubleshooting the drive.  If you have done this then I apologize for the advice.

Or you could just buy another drive and replace it.  That's assuming that your present drive is defective.

Good Luck

is it realy possible to put a loose drive into a sharp twin fami ?
is the drive exactly the same ?

[kite200]

yeah its exactaly the same

[uroko-sakanabito]

thank god (and you ^^, thats great !)
Then i will buy a loose one and replace it...
I love this little Twin Famicom and would not have a normal famicom

any idea where i can buy a cheap, working, loose disk drive from a seller with real shipping costs; one on ebay has drives for 35$ and shipping is 50§ :-(

I need to find a seller with real, working disk drives...

[kite200]

uh, you might end up paying that much if you try to buy from yahoo auctions. might as well just pay for it

Or like was suggested earlier, just buy a Disk System and swap drives. Then resell the Disk System as broken.

thats the cheapest way... i will try it
thanks

True, it really just a swap of the FDS drive.  That's how I repair really damaged Twin drives if the belt replacement doesn't work.

I finally plugged my Famicom into a tv with channel 96, and I can see it turns on with a perfect signal, but I am unable to play any games with it! Every time I put a cartridge in the Famicom, the only thing that appears is a gray screen with a buzzing sound. Controller 2 seems to be the cause of the buzzing sound on the tv, and when I put the volume higher on the controller the buzzing also gets higher and worse. What could be the problem, and what should I do?

[JC]

It seems most of us have that Controller 2 problem. It's likely just 'cause the controller is old. The only solution would probably be disabling the mic function or getting a brand new controller. As for the gray screen...I get that too sometimes. Treat it like a toaster and clean the pins or press reset a lot.
