I had one of those. 64k was plenty then. I had a VIC-20 before that. It had 5k. Actually typed out a program that was large enough to run that out of memory.
That was an awesome little computer. I've coded in Machine Language during many years on this jewel. Ahh, that was the good old time...
That was my very first computer. My husband gave it to me for Christmas and that was when he "created the monster". I've been a "computer nut" ever since!
