Re: Ah the good old days
C&VG had a covermount flexidisc for the Sinclair ZX Spectrum back in the day, and Personal Computer Games Issue 3 also had one containing all the program listings from the mag.
I seem to recall there were a few other of the popular mags at the time also carried flexidisc covermounts
