    While looking up Zilog's main contribution to computing history, I found this ad on Wikipedia: http://upload.wikimedia.org/wikipedia/commons/e/e0/Zilog_Z-80_Microprocessor_ad_May_1976.jpg Clearly, someone wanted to write off their miniatures as a business expense.

    Coleco Adam!

    It's a pretty goofy system, but I got a lot of mileage out of it thanks to its AppleSoft-compatible BASIC (except the screen was only 32 chars wide instead of 40) and a truly amazing version of Logo designed to take full advantage of the TMS9928a graphics chip. I had a lot of fun putting those 32 sprites through their paces, and the Logo language was surprisingly powerful. One of the bundled demos included a recursive routine for drawing fractles, of all things.

    But that tape drive was absolute torture.

    The Sega Master System. Pretty awesome console, and I've been enjoying getting back into its games this year.

    Mmmm…. so many choices…
    I'll throw in the MSX2. Weird japanese computers make me feel warm and fuzzy inside.

    It's interesting how the ad on Wikipedia describes the clock speeds in terms of (I assume) the amount of time a single cycle takes instead of the now-standard reverse; 500 ns should be 2 MHz and 400 ns should be 2.5 MHz. Was this common practice in the '70s, or specific to Zilog's literature?

    By far, the GameBoy would be my favorite (not quite) Z-80 based machine, followed by the TI-82 graphing calculator. I spent quite a bit of time with both of those devices in high school. I also had a TS 1000 at the time, but it never got anywhere near the attention as the other two.

    The ZX-Spectrum, very popular in Brazil (my home country) in the 80′s. Actually, I had a Spectrum locally produced clone called TK-90x.

    The Sinclar ZX-80. Tiny little thing with few chips beyond the Z80A. The design did 'bend' the rules a bit on how some of the components were used.

    BTW - I have a Zilog Z80 Assembly Language Manual (white cover) and Zilog Z80 Databook (Hardware Manual, black cover) that I used extensively while working for TRIAD Systems (CA, USA) in the 80’s – 90’s, who used the Z80, Z80A, Z80B, Z80H, and Z280 extensively as main processors, communications boards, disk/tape controller boards, and many other intelligent peripherals.
