This was something I thought of last week. The Apple 1 is an awful computer in the perspective of third party software. Anyone who owns an Apple 1 or one of its many replicas has it on display or it's showing one of the handful of things people have gotten working on it:
-The ROM monitor
-An Apple logo
-The BASIC sign-on
-A picture of Steve Jobs
-A picture of Woz
There's really nothing else. It's just one of the numerous caseless micros that started to show up on the market in the mid-70's and if it wasn't tied to Apple it would of been forgotten.
Well, at that time, there wasn't yet a market for software aimed at personal computers. That's why they came with BASIC: you wrote the software you need yourself.
