The Ohio Scientific P1 did it with a cheap DAC (which doubled as an on-board
300baud modem) and simply did raw bytes to/from the tape drive. No error
correction, so loading from tape was always an adventure even if the tape
was known good :-)

I had to boot a Plexus P/60 from tape once or twice, but that was 1600bpi
magtape. Again, it was pretty much raw data, albeit in the form of a
filesystem image written to the tape.

I agree with the question "why?" :-)
