Ahhh, the good old days. The first computer I
owned was one I built from kit form, and it had 2K of RAM, 2K of ROM, and was programmed in hex. Later there was an expansion module to take it up to 4K of RAM. It was literrally putting one memory chip directly on top of the existing memory chip, and soldering all the pins together except for one pin which was taken to a software controlled gate. The ROM had to be upgraded to handle that too.
At the time I was working on far more advanced machines: They had 16 K of ram. Way out of my price range though
Now my home computer has 756Mb RAM, and 170Gb HDD (3 drives) and a 19" monitor. Gee how things have changed.
