I had a homebrew system built around a Zilog Z80-MCB in the late seventies. Tape storage (I never did get the head-per-track 1MB drives from Newman Computer working right), a surplus OCLC terminal, and a Selectric printer with homebrew electronics. The first computer I programmed was an IBM 1620 in the mid sixties, though. An odd machine. > I'm feeling old.

It continually amazes me that the devices are still in production and widespread use. It could well be the most popular chip ever made for embedded applications.

I did try the 4004, but it had too many problems. The 8008 was bootstrapped with switches at first, then I built a diode matrix to start up the system, much faster, then I interfasted a rom again from Intel. the memory was 8KB and was driven by the CPU and ana a unit I built to work with the dynamic memory. Those were the days when men were men and systems were built by men.!!!!! Gerald -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

Windowing systems, I think, have really distorted people's comprehension about how really fast CPUs are. > It could well be the most popular chip ever made for > embedded applications. > > Miles Fidelman > -- Seek truth from facts. -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
