Amstrad ZX Spectrum +3
Sinclair ZX · 1987
The Spectrum with a 3-inch disc drive — Amstrad's own drive, from the CPC — and the most capable machine of the line. The ROM changes for the disc interface broke compatibility with a slice of the earlier software, which is the trade. Comparatively uncommon, and the drive and its perishing belt are the reason most surviving examples do not work.
