I remember both, the Z80, and my all time favorite 386 DX-40.
That and overclocking by changing clock crystals 🙂
I had a couple Z80 systems and a 386. I can't remember which 386. Maybe there was a DX-20 or 25 . . . It was an NEC "OEM" model -- the traditional desktop before tower cases became fashionable. I think there was an "Over-Drive" chip [or whatever it was called] -- and I got it. I don't think it was bundled with Windows 3.0. I think I'd installed 3.0 followed by 3.1 and 3.11. Nah . . . the 3.11 was for the 486.
