I was curious, so I took apart the external floppy that came with my A1000.
Its a basic NEC drive dated January 1988, but I was curious, and it had an adapter board "PCML Amiga Adapter" which is basically a 74HCT74E (flip flop) dated from 1987, and a 74LS38 (NAND buffer) dated 1985
for some reason I wasnt expecting to see any kind of adapter board or such.
I know "A" PCML made a sampler for Amiga but I dont know if this is the same PCML..
I just thought it was odd...
