In about 1975, I was sharing an office with a lady who
bought an Ohio
Scientific 6502 computer, with two 5.25 inch floppy disk drives,
instead of an Imsai 8800 with one 8.4 inch drive.
She got a tee shirt that said "I've got two floppies."
Except she didn't.
The 5.25" drives were called "mini-floppies"
Just a couple years later, . . .
The Shugart SA400 was released in 1976, but was hard to get for a few
years.
The OSI Challenger was, IIRC, 1978
A few years later, I got a used ["Euro"]-Apple II, converted for USA use,
in an OSI Challenger case (with wood (walnu?) sides), with an external RCA
keyboard.
I would rather have had the OSI, but that wasn't available at the
computer swap.
OSI used a PIA chip, instead of a conventional FDC chip, so WD/NEC
style controllers can not read those disks.
