Mac 400k Floppy Drive cleaning/lubrication.
I have like 3 or 4 Mac 400k drives (2 external units, and 2 internal) Is someone here adept at cleaning the old grease and re-greasing these drives? Here's the systems I need them for: Mac 512K - Internal drive & External Drive - Clean and Lube Mac 128K - Swap 800K Internal Drive & Replace with 400K drive from Mac Plus, plus clean and lube External Drive. My Mac 128K has the original mainboard, but has a 1MB RAM Expansion board sitting on top of the main board, and likely updated ROM to support the 800k Floppy drive. I also have 3 or 4 800k drives that also need to be cleaned and lubed. While it is probably something I could do myself, I've never had good luck when trying to refurbish floppy drives, so I'm looking to find someone who could do it for me. Thanks, Joe -- Normal Person: Hey, it seems that you know a lot. Geek: To be honest, it's due to all the surfing I do. Normal Person: So you go surfing? Normal Person: But I don't think that has anything to do with knowing a lot... Geek: I think that's wrong on a fundamental level. Normal Person: Huh? Huh? What?

Please talk to Tony Diaz about repair of 400k, 800k, and 1.44mb 'superdrive' apple/sony floppy drives. There is a specific order of teardown, cleaning and lubrication to be followed, IIRC. See https://archive.org/details/Kfest2010-TonyDiazDiskDriveMaintenance for his presentation on this. Tony can be found on irc.a2central.com irc network in channel #a2c.chat as tdiaz or Tony -- Jonathan Gevaryahu jgevaryahu@gmail.com jgevaryahu@hotmail.com
Tony Diaz (from A2Central) put together a really in-depth guide for the 800k/1.4M at http://apple2.org/35Drv/index.html. I haven't done this myself yet, as most of my drives work, and it's for 800K, but I believe the 400K drive is not all that different rebuild-wise. Do note, though, that connecting a 400K drive to newer Macs could fry it. David

Yes; Tony let me know that for the common "mac 512k to plus-with-512k-of-ram" upgrade, you had to swap the cable between the mac 512k mainboard and the floppy drive; the 400k original floppy drive uses a cable with a red stripe on the wire for pin 1. The 800k-in-mac-512k cable has a yellow stripe on the wire for pin 1 and one of the wires is cut compared to the red cable, since otherwise the red cable wiring with the 800k drive causes a dead short and will burn out the cable, drive, or motherboard or possibly all three. -- Jonathan Gevaryahu jgevaryahu@gmail.com jgevaryahu@hotmail.com
I'm really good at rebuilding these drives, and have done many of them - both 400K and 800K. That would be a good thing to bring to a workshop, perhaps - I'd be happy to walk people through it. -Ian On Thu, Dec 17, 2015 at 2:06 PM, Joseph Oprysko via vcf-midatlantic <vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:
