Whatever was on th ZX81, then Spectrum. Then TOS on Atarti ST Then CPM Then DOS something early, and VMS. Then some very early MacOS, and SunOS Then Xenix, DOSes 3, 4, 5, and 6. Then Windows 3.0, 3.1, 3.11 for workgroups. Then Linux something brutally raw that I didn't install myself, and Solaris Then Win NT 3.5, and HP-UX Then WIn 95 and Win NT 4.0 Then another later MacOS, Then Linux Slackware, Redhat, and Suse Then Linux debian 3, 4, 5, 6, 7, 8 During which OSX Then whatever Moto had on their phones, S40 and Symbian Then Maemo and Harmattan Then Gentoo, Then Devuan.
If there's a straight and simple upgrade path between those, I'll not count them as different (So I count 2 windows, 2 Macs, 5 desktop/server linuxes), so I think that's about 20+, but 5 were phone OSes and shouldn't count were it not for 2 of which I use as a computer (n900 and n950), so counting them.
Call it 18?
