Assembly Language Assembled for the Sinclair ZX81
Re: Assembly Language Assembled for the Sinclair ZX81
...We all knew the day would arrive when ZXDB would become a sentient being, develop super-intelligence, invent a time machine and return to 1981 so that it could fully catalogue every single piece of Sinclair history.
Its aim: To make MIA titles a thing of the past (or alternate past perhaps).
