Are there any 5.25'' floppy drives that are officially supported and which can read "flippy disks"?

Are there any 5.25'' floppy drives that are officially supported and which can read "flippy disks"?

Post by jdb2 » Sun Nov 11, 2018 7:43 pm

I have a bunch of old Apple IIe 5.25'' floppies which I think are so-called "flippy disks". I had bought an "EPSON SD-600 5.25" 1.2MB FDD Floppy Disk Drive" off of eBay, but, I don't think it's compatible with flippy disks. I really don't want to go through the trouble of modding my drive, if I can help it. Are there any Kryoflux supported 5.25'' floppy drives that can read flippy disks without needing to be modded?

Thanks,

I forgot to mention that I'd be willing to pay someone a reasonable fee to mod my 5.25'' drive so that it's flippy disk compatible. Reply or PM me if you're up to it and have the time.

Thanks,

The Kryoflux will not read flippy disks that have only one index hole opening unless you have a modded floppy drive.

An alternative for data disks is simply to punch a second index hole through the floppy disk jacket (not the cookie!). Then just flip the disk over. But obviously you would not want to do that to collectible original media. (Some disks shipped from the factory with two index hole openings so they could be used with other single sided systems)

To quote LOTR, "It is precious to me..." :P with regard to my ancient Apple IIe floppies. :) They contain programs and data that I wrote when I was 8 years old -- essentially my first programs, in BASIC of course. :)

I looked through the entire list of officially supported 5.25'' floppy drives and I couldn't find one that was "flippy disk" compatible -- the offer to mod my drive for a reasonable price is still open :)

Panasonic JU-475-3/4/5 models
Newtronics D509V2/3/5 models
Teac FD-55GFR

Those I've flippymodded. There was one other I can't remember, tho the accuracy of its mechanism might've been a bit questionable.

Panasonic can be modified without expensive tools, but the others require oscilloscope and professional alignment disk to get the job done.

Thanks for your reply! :D I have an Epson SD-600 5.25" 1.2MB floppy drive. Would modding it require special / expensive tools or is it as "easy" to mod as the Panasonic?

It all depends. What kind of stepper motor assembly the drive has, how far the head can be moved, where the head stops and what stops it there, and can that stop be removed.

Well, I don't know the details, unless I can find some type of data sheet and/or service manual. Perhaps I should just purchase the Panasonic drive you mentioned. It's selling for around $75 on eBay, which is quite pricey, but I don't know of anywhere else to find one.

I'm still willing to pay someone to mod my floppy drive, even if it means that I'll have to get a new drive off of eBay.
