Dave Farquhar Retro Computing June 25, 2024October 5, 2025

In 1992, the Commodore 64 was fading. You may be surprised to hear it was still the number three gaming computer in terms of market share in the United States, but its growth years were in the distant past. That year, a new third party disk drive appeared or the C-64. Sometimes when you do something for the last time, you don’t realize it will be the last. In this case, I think everyone knew these drives were the end of the line. But what a finale they were.

In 1974, Marx introduced a diesel freight train set it called The Champion, catalog #52750, that ran on AC electric power and sold through catalog retailers. If you have a Marx 52750 train set today, it’s worth considerably more than its original retail price, even adjusted for inflation.

In this blog post, we will cover what made this 486 so special and what made this forbidden 486 illegal.
