First Computer Memories with the Sinclair ZX81 (Download Squad)

Jan 4th 2010 12:56PM My first computer was also a ZX81 and I had the 16K expansion pack. I had to use silicon to keep the memory pack seated properly. My friend also had one and we built modems so we could transfer programs to each other. We also opened the cases and hardwired joystick ports to the arrow keys so we could hook up Atari joysticks to play games. I tried to write a program to work as a primitive operating system but 16K was not enough.

I still have my ZX81. Haven't fired it up for a long time. May have to one of these days just to show my kids.
