    7575    <p>Today's kids think of the latest mobile devices when talking about "mini computers".
    7676           In contrast, in the 1960s and the early 70s, a computer was always huge (like our
    77            <a href="univac9400.shtm">UNIVAC mainframe</a>), thus a 300kg computer was "mini".

    7878           Early computers are well worth seeing due to their enormous size and the nice
    7979           transparent auxillary devices.

    102102    Because of constantly growing claims for storage capacity, backing storage (19-zoll drawers for 4kB with a weight of 20kg) was offered. The PDP 8I could not administrate more than 32kB.

This computer, with so many peripheral devices, is probably unique in Germany. The peripherals: paper tape reader, punch card reader,  triple 8-inch disc drive, hard disc system with 38cm diameter disks (the device weights 100kg and cost 24000 DM, but only holdy 5MB), special BASIC-language keyboard, etc.</p>

    444444    <p>WANG quickly recognized that the future of computers needed screens. However the concurrent HP
    445445    computers had only a single-line LED display until 1975.</p>

    451451    <p>The first personal computer was also build by WANG: the PCS II (1975). The first PC that was affordable for everybody was the PET 2001 from Commodore. It came on the market in 1977 and was as cheap as today's PCs, but had 8kB and had decent applications. Many more home computers followed, the market got out of hand and therewith this collection of computers ends.</p>
