The old computers were so relaxing. You could go and make tea or even have lunch while you waited for them to load a program. For the impatient there are always emulators that will make use of the much faster loading from hard drive. click here
I have one in the loft along with a PET, a Dragon, a BBC Micro and a Sinclair ZX81. I had a Sirius 1 but foolishly loaned it to a colleague andd never got it back. They are all carefully wrapped and hidden for someone to find and take to a distant future antiques roadshow. I was tempted to stick a VCR up there as well but I think, like the LP turntables, they will still be in use for years to come by too many people.
They were just prior to my interest in computers but I can remember having to play about with volume and azimuth adjustment to get programs loaded on a Spectrum. A pair of Microdrives cured that but it was a pain, not to say expensive, transfering programs to Microdrive cartridges.
I had a Spectrum, than an Amstrad 464, but most of my mates had either a C64 or a BBC B. They were all great gaming machines in their own ways. I did get to play quite a few C64 games (and Vic-20 games!) back then, and I once swapped my 464 for a C64 for a couple of weeks. I even bought a few editions of Zzap 64! magazine, even though I didn't own a C64, lol.
Favourite C64 games:-
Paradroid (still good to play now. Paradroid '90 on Amiga was very good, too) Dropzone (excellent Defender type arcade game) Kickstart 2 (budget motorbike game, great for 2-player) Pitstop 2 (Formula One game, probably horribly dated now) Winter Games (Looked amazing at the time)
