Do you count machines like the Amstrad CPC464 which had a built-in
cassette recorder?
And don't forget the Commodore cassette port - used on the PET, VIC,
C64, ...
I didn't. It was in the email this was a reply to:

Lots of systems had dedicated cassette ports, but yes, CoCo has a

the Model 1/3/4 also, and doesn't the Apple II have one as well. I am
sure I am forgetting a bunch.
This blurred the line between built-in cassette drives and cassette
ports, since the built-in drive on early PETs became the separate
drive on later ones, plugging into the same port.
Maybe less so than initially thought, as early PETs had 2 cassette
ports, so I think that kept people from thnking the cassette drive was
some "internal only" thing. The second cassette was addressed as ,2,
with the internal being ,1
Also unusual, I think, was that it didn't use a modem chip to generate
tones, but bit-banged them in software.
Not sure how many systems did that, but it was not a CBM exclusive.
Tandy did that as well on the various 8 bit platforms it offered.
