Oscar Toledo G tells of his adventures in 1995

In my previous article I talked about how I managed to create a self-contained operating system for transputer. This included the basic operating system, a text editor, a Small-C compiler, and an assembler.

The year was 1995, I was age 16, Lemon Tree and Zombie were being played in the radio, ARPANET closed around 1990, and it started to be known as Internet, and in Mexico only a handful of people used it through Compuserve Mexico. I wasn’t so lucky to have this service.

The good old days when 128K could run most anything. It also was the last of the times
when one could design computers with off the self parts, and still be fast with slow I/O chips.
