No, but it most certainly was a bit-serial interface. As, for that

If you mean a serial interface using RS232 levels, then at least on this
list it's best to say so. Do you insist that it's asynchronous, or are
synchonous RS232 interfaces included (IIRC the RML480Z used one for its
floppy disk system)

Um, that wasn't any relative of RS422, RS423, RS232 or anything akin All fair points, but then, who ever used serial
ports to connect mass
storage? (I know there was a serial port hard disk for the first ever
Mac, but that was from complete lack of any alternative.)
I can think of the Commodore 64- 1541 drive to it, was it? I thought it was some serialised
variant of an IEEE
interface, as used on the PET machines...
Err, considering there was a shop selling them on just about every high
street, I asusme some people (other than me) actually bought them.

and the external floppy drive
for the Tandy Model 100.
This one I didn't know about, but Tandy machines were never very big
this side of the Atlantic. /Way/ too expensive for most Brits.
