Sinclair Spectrum 48k - Double Restoration | Original Spectrum and Spectrum Plus

Two eBay purchases - both bought as "untested". I wanted to find out what the difference was between the original Spectrum 48k, and the later Spectrum Plus. Both machines are repaired and restored, and checked out using the Retroleum SMART card and diagnostic ROM. I then put the keyboards through their paces to check out the improvements made to the Spectrum Plus.
