The World's First Laptop
« on: August 17, 2007, 05:55:36 PM »

The world's first laptop or 'portable' computer -  the Osborne 1 -  was marketed in 1981 for $2,000:

It's spec was:

    * Dual 5-inch, single-sided 40 track floppy disk drives ("dual density" upgrade available)
    * 4 MHz Z80 CPU
    * 65 kilobytes main memory
    * Fold-down keyboard doubling as the computer case's lid
    * 5-inch, 52 character 24 line monochrome CRT display
    * IEEE-488 port configurable as a Parallel printer port
    * RS-232 compatible 1200 or 300 baud Serial port for use with external modems or serial printers

It was powered by a wall plug, and had no internal battery, although a battery pack offering 1 hour run-time was available.

Yeah lol, but I guess it was state of the art technology for 1981... remember this was 3 years before the IBM 286 was available.

But think about it, all the latest web browsing phones and palm computers have screens that size and smaller. so if fact we have got knowhere in the intervening years....  ::)
OK so the surrounding kit has got smaller but you are still squinting at a tiny screen but now with a miniscule keyboard as well.  ???

I know what you mean Ralph... I swear my mobile phone was made for a teenage girl's fingers to use.

Given that's probably the biggest target market, it wouldn't surprise me!!

Yeah well, I'm all for shrinking the technology, but it still needs to be functional... my mobile is a pain for me to use, and I've got hands that are below average size for an adult male.

When my mobile contract comes due for renewal I check with the supplier what free upgrade I can have with all the bells and whistles, take it and continue to use my old chunky one, then after a month or so, sell the new one on Ebay..... ::)  Am I supposed to do this????
