Dead floppy drive in this Amiga 1200, let's fix it.

Ғылым және технология

WARNING: This video shows recording of a CRT with a lot of flicker.
If there's one thing I enjoy its working on an Amiga and this episode we are looking at an A1200 that belongs to another local enthusiast. I've previously done some work to the PSU of this machine but the owner contacted me a couple of days ago to ask if I'd take a look at the floppy drive that had stopped reading disks. Lets see if we can get it fixed.

    This was very useful. My A500 chinon drive doesn’t work and it could be the caps it would seem. For what they cost it would be worthwhile replacing them. I’ve never done it before but it looks very straightforward.

    Although my A1200 already was recapped by the previous owner, it's always interesting to see these kind of videos, as you can still learn things from it. 1:53 The actual version 1.20 of Amiga Testkit can be used from WB, too. But not older versions.

    @@PJBonoVox What? People on the internet are wrong? Well, I've never! Also, yes, it's most likely just IPA. 99% is completely fine to use on electronics, and does not damage it. If you are unsure if your cleaning solution is good, just put a cotton swab in it, and wipe it on a clean mirror surface (easier to see there). If it leaves a film after evaporating, to not use it to clean heads and so on. (97% is also completely okay, but 70% and likes I'd be careful with due to dilution and water content.)

    It's not "ew-ef", it's microfarads (μF). The "u" is an ASCII glyph approximation of the greek symbol for "mi", μ (often falsely described as "mu"), hence micro. For example, you might have seen latency printed "us", that's microseconds, μs.

    Great video, have this issue on one of my amigas, now i know the cause. Would be great to see a you do the Floppy Fix for the Escom Amiga 1200's to use an amiga drive instead of the pc floppy drive that Escom put in due to an amiga floppy shortage at the time which caused me so much grief back in the day trying to load so many amiga disks from boot.

    I don't have an escom 1200, both mine are from the Commodore days. I had always thought that they simply modified a PC drive to work in the Amiga rather than actually modifying the 1200s board? Can you not just swap out to an Amiga drive and it works?

    @@CRG unfortunately not. There is a fairly easy tweak to make on the motherboard with a single wire that escom had added to the bottom of the motherboard at the floppy port. I know that you have to move one end of that wire to another pin before you can make the amiga reuse a normal Amiga floppy. I believe there is also a tweak to make on the floppy drive too, although it might be just to do one or the other. If you google “escom floppy fix” and also youtube and you’ll see what i mean.

    Great timing Glen as my A1200 FDD has the exact same symptoms and I need to take a look. This will be really helpful. I'm hoping it's just in need of a clean as it was working on and off, but maybe it's caps. Did you test the old caps after removing them to confirm that they were the problem?

    Thanks Chris. Its seems like the caps are a common problem in this model of drive. I didn't test them to be honest but they are still lying on the mat along side the motherboard so after the recap of that I will take all the caps and test them to see what state they are in.

    I have a question in regards to floppy drives and a1200.... If the 1200 boots any disk, but do not detect floppy swap. And does it on every disk drive, including gotek drive. And the board is a Commodore and not Escom. Then what to look for?

    First thought would be the change signal. It's on pin 2 at the drive and runs to pin 7 on via U7. This line should go low when the disk is removed.
