Furthermore you can see the PDP 8L or <a class="go" href="/en/devices/pdp_8I.php">PDP 8I</a> (year of manufacture 1967, a lot of periphery) and the laboratory computer <a class="go" href="/en/devices/lab_8e.php">LAB8e</a> (1971). 102 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. 103 <br />THe PDP 8L, a trimmed-down version of the PDP 8I, cannot hold more than 8 kB.</p> --> 104 105 <h3>Classic PDP-8</h3> 101 <h3 id="pdp8">Classic PDP-8</h3> 106 102 <div class="box left clear-after"> 107 103 <img src="/shared/photos/rechnertechnik/dec/pdp-8.jpg" width="400" height="560" alt="PDP 8 Classic" /> … … 155 151 156 152 157 <h3 >PDP-8I</h3>153 <h3 id="pdp8i">PDP-8I</h3> 158 154 <div class="box left"> 159 155 <img src="/shared/photos/rechnertechnik/dec/pdp8i.jpg" alt="DEC PDP-8I" width="400" height="666" /> … … 352 348 </div> 353 349 354 <h3 id=" 8e">Lab-8e, PDP-8e</h3>350 <h3 id="lab8e">Lab-8e, PDP-8e</h3> 355 351 <div class="box left"> 356 352 <img src="/shared/photos/rechnertechnik/dec/lab8e.jpg" width="400" height="461" alt="DEC LAB-8e" /> … … 440 436 441 437 442 <h3 >WANG 2200 with bulky peripheral hardware</h3>438 <h3 id="wang2200">WANG 2200 with bulky peripheral hardware</h3> 443 439 <p>Next, the first system that looks like today's computer is presented: <a class="go" href="/en/devices/wang2200.php">WANG 2200</a>, year of manufacture 1973. 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> 444 440 <p>WANG quickly recognized that the future of computers needed screens.
