I distinctly remember small MFM drives being offered for sale that replaced one of the
internal floppy drives, although presumably they connected through to something other than
the floppy drive connector on the mainboard. I also remember not being able to afford one
at the time!

So what is it called in the UK? We call the end-of-sentence marker a
'full stop', not a 'period'.
it serves as punctuation separating an integer,
and a 2 digit decimal
integer.
Does that mean that the correct way to pronounce the verisons are 'three -
thirty' and 'three - thirty one'?

Also, for those using hard disks, 3.30 had a 32M
size limit.; 3.31 was the
first version without the 32M limit.
AFAIK the PPC640 never hard a hard disk. There were a pair of D conenctors
(DB25 and DC37 I think, I forget the gender) that carried the system bus.
There is rumoured to be an expansion chassis for it, I've never seen one.
I also beliecve that US versions diddn't have those connecotrs fitted,
due to the FCC emissions regulations. I guess it would support an XT hard
disk controller (with its own boot/BIOS ROM) connected there, but I've
never seen it done.
