Pentium PCs became widely available towards the end of 1993. I remember this because my first "PC" was a 486 DX2-66 that I got not long before Pentiums PCs started showing up. The Commodore 64 was pretty dead in the U.S. by 1992 but in the U.K. and maybe some other parts of Europe there was still a market. I think Commodore was manufacturing Commodore 64s all the way up to the point they went bankrupt in 1994 or pretty close to it.

This was the last issue of Zzap! but it's successor, Commodore Force, continued on for another couple of years until March 1994 still exclusively covering games for the Commodore 64.
