computer) working from Radio Electronics, but it was just too difficult.
Too little experience, too many chips, too poor a design, etc.
Then along comes RCA with the 1802. The sales rep even let me borrow
their "Microtutor" demo to get me hooked. Then Popular Electronics
published the Elf (their version of the Microtutor) and away I went!
I still feel the 1802 is an elegant design. Sure, engineers can always
add more features. It's easy to encrust chips with so many "features"
that no one ever really figures out how to use them all. They wind up in
products that are expensive crash-prone power hogs.
A design is "done" not when you cannot think of anything more to add;
but when you can't think of anything more that you can take away. :-)
