Famicom Twin disc calibration

ProtonXProtonX
in Help Wanted!
I have accumulated 5 sharp famicom twins- and even though I can replace the belt, I just do not have the time to figure out the drive settings.
I successfully did one, but there is definitely a trick I do not know.
I'm more than happy to pull the drives and send with one complete system. I have lots of item for trade- and or I'm willing to pay.

If anyone here does it let me know- or if they can direct me to someone reputable who has done a few.

    This might apply to a Twin Famicom. This doesn't help if you've screwed around with the delicate timing hardware already, like a lot of bad guides suggest.

    The disk drive is the same in the FDS & the external drive. So the posted guide should suit your purposes.



    That said, did you look at these youtube videos as well?

    Unfortunately I personally don't have the time to figure all of that out- anyone?

    Literally the laziest thing I've seen all week, lol. Really, dude? The one that Guntz showed would take you less time to do than you reading about posting 2 MONTHS! a part. Maybe 10 minutes, if you need to find the right screwdriver. I vote for Guntz method as it's what I learned from Famicomworld.

    Really- I'll ignore your comment for the most part. If it was as simple as the picture I would have done it. You evidently know nothing about the twin drive and how it has more than 1 calibration point.



    I'm looking for someone who specializes in fixes these. I have hundreds of game systems (literally) to fix and don't have the time investment to learn these.

    If you have tampered with the delicate timing adjustments in the Twin Famicom FDD drive at all, you are gonna be hard pressed to find someone willing to get them re-calibrated. These things are really annoying to work with.



    The key thing here is (that you don't want to listen to) is that the Disk System's FDD drive doesn't suddenly become out of alignment just because the belt fell off. All you really have to do is put the new belt on and get the drive setup to start reading at the beginning of the disk, which is really easy to do (see my picture above). The FDD drive is completely linear and incapable of seeking, literally all it takes to get constant read errors is to get the disk started anywhere other than track 0.



    I suppose you could try contacting retrofixes about installing new belts, but it'd be a lot cheaper and quicker in your own hands though.

    Finally found someone.



    In case anyone needs help with this- I had several drives calibarted by a guy on Assemblersgames forum under the name skyway1985.

    All the drives had multiple adjustments messed with.
