I wasn't a Commodore user, but as I was heavily into home / hobbyist computing at that time, they had a huge influence on me. At the time, we mostly used TRS-80s and the like, but my school had C64s and I vaguely remember trying to make sure that BASIC code from a book for C64 users would work for me.

And only today did I find out that Tramiel was a Holocaust survivor who became one of the most influential figures in the computer revolution of the 80s.

My thoughts are with his family and those who knew & loved him.
