Not just for geeks anymore. Well, maybe you still needed to be
a little geeky. Before prebuilt, preprogrammed computers like
the Apple II and TRS-80 arrived, anyone who craved one of

The computers came with between 8K and 60K of memory, about the amount required for a Palm Pilot add-on program today.
