I got interested in computers in the mid-70s before they became mainstream, and designed my first at age 15 using TTL chips from Radio Shack. Over the years I've learned and used about 20 programming languages including 8080/Z80/8051 assembly, multiple dialects of BASIC, C, VB, Prolog, Access, Paradox; and in the web age - html, PHP, Perl, Javascript, SQL, bla bla bla.
