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> 446 <p>WANG quickly recognized that the future of computers needed screens. However the concurrent HP 447 computers had only a single-line LED display until 1975.</p> 448 449 <div class="box center"> 450 <a href="/en/devices/wang2200.php" name="backlink-wang2200"><img src="/shared/photos/rechnertechnik/wang2200.jpg" width="592" height="402" alt="Wang 2200" /></a> 451 </div> 452 453 <p>One of 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> 454 455 <p> See further details at <br> 456 <a class="go" href="/en/details2.php" title="Details 2"> the tabular overview of 457 mid range data processing equipment and proffessional early computers</a>.</p> 458 444 -
