Hell, I had an arrhythmia computer in one ICU that used a platter that was 24” in diameter, iirc. Booting that bad boy up after a shutdown was a nightmare, took about five minutes and was common to have it crash on startup. Worse was the unit at another facility, it booted up from a paper tape spool, and though it never tore and always managed to boot up without a glitch, it was quite nerve wracking

If you're adding in extras, I’ll claim your 22 and add in another for my V-Cord II, a precursor to VHS and Betamax by Sanyo that was the first videotape player able to pause the picture. Add another for saving files from my Texas Instruments TI-99 to a cassette tape. That puts my score at 24, if you’ll allow it
