    275277           computer was purchased in the basic version which was barely affordable. Afterwards
    276278           more options were installed step-by-step. That way the enormous acquisition costs
    277            were distributed over several years and the computer was always up to date.

     285        <p class="small">(Google-translation!):We have a PDP-12 price list from the year 1973, a period in which the PDP-12 was already an outdated model. Our fully-equipped computer was a PDP-12 LDP (Laboratory Data Processor), here specifically a "clinical lab12", sold at a price of DM 206.700. Most of the options listed above were built in. (In 1973 3,50DM corresponds to 1$).<br>
     286        This computer was equipped with 4kB Memory Core. So one needs in adition a "Memory Extension Control" for 16.600 DM and a 4kB Memory Module for 25.100 DM. The price for the unimposing Peripheral Expander BA12 was 5.400 DM (equivalent to a midsize car) and "High-Speed Paper Tape Reader/Punch" incredible 16.200 DM.</div>

     290        A Disk Cartridge Drive RK05 where sold for DM 21.200, where one needs in addition the "Positive I/O Bus to Omnibus Converter" DW8E (6750 DM). Similarly is the Converter DW08A and the Cabinet AA50 for additional D/A Controller. The 3 plugged D/A modules were calculated with 1.680 DM per unit.
     291        The memory expansion to 32K does not appear on the list, but the price for this option was about 50.000 DM including the controller.<br>
     292
     293        In the sum it is a staggering number of 387.690 DM, which is today corresponding about 500,000 € or 600.000 $!</p>
