as an unemployed computer science graduate when this came out this CPU was a big deal to me. I had just finished a subject on MINIX and had read Linus original Linux post,and getting a cheap 386sx mobo allowed me to get into Linux for relatively low cost at the time by upgrading my 286.
Same here. The 386SX meant that I could afford to buy one just for screwing around with Linux (which at the time was very much a bare-bones ubergeek thing...).
