I worked on them for a couple of years back in the day. Still carry the
trauma.
My question is, was its basically really
"built" using TTL logic/chips?
The system didn't really have a microprocessor (neither did the early
Alto, right?)
So your question isn't really about the BASIC, I guess, but about the
hardware?
I recall that system had many boards, the whole
"CPU" box was external to
the monitor (and in the earliest versions, the power supply was also a
large external box). I can't really fathom creating a BASIC out of raw
TTL, or maybe I'm misunderstanding the approach.
You build up a CPU (and the rest) from TTL, just like before that you
would have built it from discrete transistors or even tubes. All a
microprocessor is is just a bunch of TTL-like MOS logic circuits
(made of metal oxide semiconductor elelements) combined on one chip.
