Yikes -- I guess it has been that long.

Try building a Content Addressable RAM (which it was) with 1970's technology
and see how much heat you have to dissipate

Nope! -- The 1610 was a totally different animal, originally built for
Honeywell as a process control engine. However, it did have a Peripheral
Interface Controller chip that no one at headquarters on Long Island could
figure out how to sell. (Hint, Hint)

No thanks, in addition to being unfair competition, I get enough physical
opportunities to demonstrate that while Bill Gates was building a traffic
counter with Paul Allen, I was making little colored squares move on a screen
and have somewhat less net worth than either!
