The OS was in a ROM. It was pretty slow, so the second OS I used was none at all, Z-80 machine code hand-assembled from assembly language. A full two player battle tanks game in less than 200 bytes. And it was too fast (4kHz CPU, today's are measured in gHz) to play, I had to add loops to slow it down.
If you can program in BASIC, learning assembly is easy.
