  1. I knew it was an acronym, but couldn't remember and couldn't
    be bothered to check what it was. I think it was one of those
    things where the words behind the acronym weren't as important
    as the acronym.

    Computers, homebuilt from the ground up :-

    There was a set of books based on the 8080A, and a single board computer
    that went along with them. You had to build the SBC, mine was wire wrapped,
    program the the startup prom, and supply power. Input was in octal, thru a
    keypad and output was thru leds that monitored the data and address busses.
    Then you could follow the lessons and interface the SBC to DACs, displays,
    8259's etc.
    Along the way you would learn assembly language, digital electronics, and
    how to interface the two.
    Getting some of those old chips might be impossible.The 8080 might have been
    Intels first processor. I don't think it ever made it into a PC type of
    application but the 8085, 8086, 8088, 286 and so on, all got their start
    with the 8080.

    The three books I have are all from Howard W Sams and Co
    The 8080A bugbook - microcomputer interfacing and programming.
    Experiments in digital electronics and microcomputer interfacing and
    programming book 1 and 2

    I have just discovered PICAXES - they are easy to program, cheap to buy,
    and you can build lots of interesting projects with them. For a start
    have a look at

    and then follow some of the links on that site

    It seems to me that many of these small computers are roughly equivalent
    to todays microcontroller systems, but they give you a UART, ram, some other
    IO, and a processor all on one chip.

    some of the older chips (like 6811) even have free monitors avalable
    , while some of the newer once only have pc-hosted cross compilers.

    It's not so hard. FPGAs are wonderful devices. ;-)

    To you and me, perhaps, but it seems to me that the OP is reaching for
    the moon in one step.
    Possibly better to follow the others' collective advice, and start
    with a ready-made simple CPU.

    There is a smiley there, ya' know. That said, I'd ratehr encourage people
    in a positive direction, rather than saying "it's imposible for a moron
    like you". Even if he never builds a processor, just making it through
    the tools would put him ahead of half the engineers.
    The OP wanted his OWN computer. DOn't tell him it's impossible to do.
    The other articles about building an 8080 (Altaid or MIPS) were far less
    usefull. Hell, if one wanted to build any "computer", a few hundred will
    buy one at Wallmart, or another hundred (plus a screwdriver) will get a
    better one from NewEgg. That *wasn't* the question though.

    How about something like this:
