My first computer was an Amstrad 8256 (also known as the Joyce). It came with a 3" drive. They worked ok but were expensive. After a while I installed a standard 3.5 " drive in the second drive slot. Besides being cheaper and much easier to obtain, they also had twice the capacity, as I recall. Over time I also installed a modem and replaced the 8 bit dot matrix printer with a 16 bit one.
Had a pcw8256 . Learned z80 assembly and cp/m. Added line drawing and pixel plotting to locomotive basic. Fun times :)
Thx. Didn't know until now that 3" floppies even existed
And speaking of Matsushita setting up a dedicated production line for the 3-inch floppy drives, they will have done the same for the dedicated 2-inch floppy drives production line 5 years later:
