[regarding the Apple I terminal] Did that solution come to you in a flash,
or did you dream it, or was it on the top of your mind upon awakening
Êone day, or a serendipitous confluence of events, or Ê.... (you can see
I am very interested in the creative process). May I send this email to
Terry White for our club newsletter? : )
Woz:
The terminal portion
of the Apple I was designed a year before I even started designing a microcomputer.
I built it to access the ARPANet after seeing my phone phreak friend John
Draper (Captain Crunch) accessing this incredible thing. I even let a
timesharing outfit in Mountain View (Call Computer, Alex Kamrodt) build
and sell these terminals but he didn't go far with it. The ideas for it
were a blend of trying to minimize chips and cost. With the Apple I this
TV terminal was just tacked on. The only integration was to use the terminal's
horizontal and vertical counters to provide complete sequences to refresh
the dynamic RAM of the Apple I. Oddly enough, the Apple I and Apple ][
were the only early hobby computers to use dynamic RAM. It took a bit
of engineering but saved me tons of RAM chips because the DRAMs were 4
times as dense as SRAMS (Static RAMS) that others used. The 4K DRAMs used
in the Apple I were the first RAM chip ever that was cheaper than the
core memories of every computer before (minicomputers and mainframes).
Sure, you can
do what you want with the email. I copied Al, my webmaster, on it and
he could have posted it on my website. I never have time to check on what
he posts. I figure that I'll have a lot of my book written if I get enough
good questions.
