I got my first Commodore 64 in 1984 and I still have it now - it works just fine. I have the monitor, printer and disc drive and still use it for amateur radio, packet programs and morse code also. I used to use my Commodore 64 in college also.
The Commodore 64 had a built-in keyboard and an external disc drive. Programs were saved on 5 and a 1/4 inch discs and it took many discs to load some programs. The Commodore 64 had 64K bits of memory, of which 32K was available for usuage and as a word processor it was hard to beat, even into the late 80's.
Commodore actually had a GUI before Apple had theirs. The games were fun and some were very challanging.
There are still many Commodore 64 users in the world today and many emulators are available on the internet.
All in all, the Commodore 64 was a fantastic machine... and still is! (As was its baby brother the VIC 20)
