I open this thread just to share a curiosity.
I only knew Amstrad and Tatung as systems that used the Hitachi 3-inch format.
But I was surprised to find this ad in Byte magazine from March 1983 (  https://archive.org/details/byte-magazine-1983-03-rescan/page/n60/mode/2up?view=theater  ) announcing a three-inch drive for the IBM PC.

The Sega SC3000 had a companion unit with a 3" drive.

On the silly side of things, you can connect a FD-1 disk drive to a Dragon disk controller and it will work  :)

The Spectrum +3 would be another notable example (although that's basically Amstrad again)

Though people forget that back in the early to mid 80s the choice of disk drive wasn't really as clear cut. It was really IBM "blessing" the 3.5" format, by including it on their PCs, that subsequently led to it's dominance and making most of the other variations obsolete.

Check out this beauty for the Famicom. The engraved brand was tested by the disk drive, to ensure it was an original disk.

The company Amdek made a dual 3in Disk drive for the Atari XL/XE too.

The drive is boasting 1 megabyte unformatted capacity. That must be across two disks surely?
An expanding array of hardware available at www.cpcstore.co.uk (and issue 3 of CPC Fanzine!)

"unformatted capacity" is a marketing con, the value is entirely unverifiable (after all, you can't use the disc until it's formatted) and therefore essentially meaningless.

As I know first was Yamaha with FDD for own MSX, and Yamaha Midi keyboard with build 3" FDD.
I can't find picture. :(

Sega SF-7000 for Sega SC-3000, it Master System + more RAM & ROM with Basic.


Timex FDD 3000, could work as seperate CPM terminal with keyboard, or as FDD for Timex and Spectrum computers. There was no rubber belt. Two drives version only.



Or little cheaper version FDD3, with only one drive and less RAM, no CPM option.


Unipolbrit 2086 with huge FDD 3". size like old 1541 for C64. It has two ports for Kempston Joystick.
Timex and Unipolbrit had 164K per side with catalogs, later version 640K per disc.


Bosman 8, CPM with 512K, and one 5.25" drive option, or two 3" drives, on picture.


Tatung Einstein TC1 and 256, with Power Supply inside monitor before Amstrad CPC.


Oric Atmos and two kind 3" FDD, Jasmin and Oric Microdisc.


Amdek with Amdisk III (1 or 2 drive version), (180K or 720K drives), with interface for many different computers those times like IBM PC, Tandy TRS-80 and CoCo, AppleII, Atari 800/XL, Thomson...

And all of them before Amstrad with CPC, PCW and ZX+3. :)
In STARS, TREK is better than WARS.

@ZbyniuR I think that you have listed all of them. 8)
About the SC-3000, it is a SC-1000 hardware, not Master System.
