8    <h2>Programmable third-generation calculators with early IC-technology</h2>
10      <p>With the development of IC-technology 1967/68 brought along with the development of
11      high-performance calculators. We have also arrayed what was among other things the
12          world's most expensive desk calculator: the WANG 700. This device outshined everything
13          else on the market (costing with very extensive
14      peripherals well over 70000&nbsp;DM or 35000&nbsp;Euro).
15      Furthermore the first calculator with an alphanumeric display (HP 9820, 1971) and the
16      world's first BASIC-programmable desk calculator (HP 9830, 1972) are installed.
17      With these systems you can marvellously plot function graphs together with labels.
18      Three years before something like that was unimaginable!
19      In 1971 the first scientifically programmable "pocket calculators" with the size of
20      a matchbox came on the market, too.

25          <p class="bildtext">In this photo you see the extract from the <b>WANG 700</b> installation.
26          The core is a calculator with two-line nixie-tube display, 2&nbsp;kB core memory and
27          integrated cassette tape for program recording. Right in the front is the
28          Mark Sense card reader, the manual card reader behind.
29          The programming, a numerical assembly language, was very fiddly.
30          The plotter program contains 794 (!) commands. An HP-Calculator (eg. 9830) could execute
31          a much more comfortable plotter program (HP-Basic) with only 36 commands two years later.</p>

36          <a href="/en/devices/wang700.php" title="Detailed Photo of WANG 700"><img src="/shared/photos/rechnertechnik/wang700-anlage.jpg" alt="WANG 700" width="600" height="438" /></a>
37          <p class="bildtext">Unique system <b>WANG 700</b></p>
38          </div>
40      <p>The picture shows a unique system with a <b>WANG 700</b> at its heart. It is a one-of-a-kind machine and was built specifically for the department of mathematical didactics of a German university. Students of pure mathematics were forced to compete for the scarce CPU time on the university's mainframe while students of mathematical didactics had exclusive access to the system shown which eventually led to some arguments between both faculties.</p>
41      <p>On the left the calculator itself can be seen &ndash; it features a two line display made from so called NIXIE-tubes, has 2 kB core memory and a built in cassette drive for mass storage. For years this machine was the fastest desktop calculator in the world.</p>
42      <p>In the middle the optical reader can be seen (which, in fact, obscures the manual punch card reader which can not be seen in this picture). On the right is a modified IBM selectric typewriter which can not only be used to print out text, but to create plots of functions as well. Below the calculator an alphanumeric keyboard can be found; on the bottom an additional dual cassette tape drive is located. Programming of this machine was quite cumbersome - a simple plotterprogram took 794 program steps to perform a task which could be done on a later HP desktop calculator like the HP 9830 in only 36 steps using HP-BASIC as its programming language.</p>

52            WANGs versioning scheme is a bit unusual: The computers were released in this order: 700, 500, 600, 400.
53            <br>The Wang 500 (year of manufacture 1971) is a pared-down version of the 700.
54                The most important scientific functions were programmed directly in the
55                threaded ROM, they did not have to be loaded via cassette any more. In the
56                upper left they embedded a small drum printer (The Olivetti P 101 already
57                featured such a printer in 1966). The cassette drive for recording programs
58                is the same like in the 700. The "marker card" reader (instead of regular punch
59                cards, the fields are only blackend) was perfect for schools and
60                universities. Many users could mark cards manually with a simple pencil and afterwards
61                test them on a single computer.
62                <br>Wang promoted the computer as "The World's Second Most Powerful Calculator"
63                (Wang 700 was the first one). This slogan could only refer to the computing speed,
64                since the HP 9100 was much more universal. The 500 series is very rare, since
65                it was superseded by the Wang 500 shortly after being released.
66                The computer in the picture is new and unused. It has been found in the basement
67                of an old stock from Wang and was passed to the museum, still unused. Therefore
68                it looks great, even being more than 40 years old.

76                <p class="bildtext"><b>Diehl Combitronic</b> with paper tape reader and puncher</p>
77        </div>
79        <p>
80        In 1970-72, DIEHL selled the Combitronic, featured with germanium transistors from the early 1960s
81        (used for the printer interface), (still) a paper tape used for booting, a slow delay line memory and ceramic
82        ICs (modern LSI technology). This device is a prime example for the enormous speed of development of new
83        technology. The transistor logic was implemented by simply taking four LSI ICs together. Therefore the
84        computer is logically (almost) identical to the almost obsolte Combitron, but the case is much smaller and the whole
85        computer shrank up to two small boards (see <a class="go" href="/en/devices/diehl-combitronic.php">detailed pictures from the
86        Diehl Combitronic</a>). In the picture above you see the compatible paper tape puncher ELS 850 and the reader
87        "Dilector" on the left.

94          <div class="bildtext" style="margin-left: 335px; padding-left: 2em;">
96    <p>While DIEHL still emphazised the mechanics, HP tried to hide it as much as possible. For scientifical calculations
97       the Diehl computers from the series shown above were too slowly, compared to HP or WANG, whereas the Diehl devices
98       were much cheaper than the others. On the other hand, for normal calculations in engineering offices the
99       perfomance of the Diehl devices was quite sufficient.
100    <br/>For large scientifical calculations or even more complex jobs you
101       had to buy Wang or HP devices.</p>
103      <p class="left">The history of development from the HP-desk calculators in one rack:</p>
104            <ul>
105              <li>In the center there is the HP 9100 (see
106                  <a href="/en/computer/programmable.php#Hewlett_Packard_HP_9100">Programmable
107                  second-generation calculators</a> for description)</li>
108              <li>Above the successor model HP 9810 (same logic like the HP 9100
109                  but uses TTL-ICs), uses the very first LED displays that are
110                  still very small and have only three rows.</li>
111              <li>At the bottom the next model, HP 9820 (year of manufacture 1971)
112                  with alphanumerical 7x5 pixel LED display.
113              </li>
114              <li>At the top the best known computer from HP: HP 9830, year of manufacture 1972
115                  with paper tape reader, puncher and plotter. This is the world's first desk
116                  calculator that can be programmed with BASIC.</li>
