I was thinking of how to use them. I think I've installed grub for dos on a floppy before and also tried plop.
Even pupngo is too large for a floppy but technosaurus built a version of linux small enough for a floppy called microsaurus, which he/she started rewriting as PLING.
After word of microsausus; I started to thinking about floppies again. I discovered that they have been in some cases been replaced by floppy emulators. So I started searching for floppy emulators and I found what seems better.
My understanding is the Bytecc BT-146 has both a 34 conductor floppy cable and a USB connection (but please research this if you plan to buy). So this means that I can use it on old computers with the 34 pin IDC [1] floppy connector or newer computers via a USB port.
It can use both 3.5" Floppies (1.44 MB) and various types of flash memory
https://www.cdw.com/product/Bytecc-BT-1 ... ve/3004574CompactFlash Card type I, CompactFlash Card type II, Memory Stick, Memory Stick Duo, Memory Stick PRO, Memory Stick PRO Duo, Microdrive, MultiMediaCard, SD Memory Card, SDHC Memory Card, SmartMedia Card, xD-Picture Card
From the picture it looks like it might also support the larger floppy disks but I don't see that anywhere in it's specs.
The prices are $19.99 on CDW, CDN$ 47.07 on amazon, out of stock on newegg and KMART and PPCS,
Anyway so one of the flash formats that it supports is SDHC Memory Card size which according to google holds between 4GB and 32GB. Puppy can pack a lot of stuff into 32GB and the nice thing about SD cards is that you can store a lot of them in a small space. I don't know if their will be any issues trying to boot from a 32GB SD card with this device. For instance if one tries the superfloppy approach then it is limited to 16GB or less according to the Feb 2017 news letter. Earlier supper floopy tests were only at 512 MB (see BK's 7 Mar 2017 blog post)
I had not luck with SD card boots or superfloppy boots in the bast but maybe this hardware would help solve the problem . Note that if someone has a newer computer they may want something like the Kingzer 3.5 Floppy Bit Panel USB3.0+USB3.0 Card Reader CF/SD/MS/TF/XD/M2 which connects to the motherboard via a 20 pin USB 3.0 interface instead of the 34 pin IDC interface.

1 - the specs on cdw say that it has a 34 pin IDC connection.
