µP<p>In april I exchanged my <a href="https://mastodon.social/tags/THAT" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>THAT</span></a> <a href="https://mastodon.social/tags/AnalogComputer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>AnalogComputer</span></a> for a Leybold-Heraeus teaching analog computer from the 1980s. Then I found out anabrid had sold-out THAT. I spoke to Bernd Ulmann (from anabrid) and he did not know if there would be another batch of THAT computers. This sunday he anounced a new batch, I ordered a THAT and a few moments ago it arrived!</p>

µP<p>In Bonn there is a stall with vintage and used books. For 5 Euros I just bought a <a href="https://mastodon.social/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>math</span></a> text book from 1968 that contains a chapter on <a href="https://mastodon.social/tags/AnalogComputer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>AnalogComputer</span></a> <a href="https://mastodon.social/tags/mathematics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mathematics</span></a> and programming:</p><p><a href="https://mastodon.social/tags/Paperware" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Paperware</span></a></p>
µP<p>The power supply of my new Leybold-Heraeus <a href="https://mastodon.social/tags/AnalogComputer" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>AnalogComputer</span></a> needs some technical attention: it only provides -1.46 and +5.4 Volts (instead of -10 &amp; +10). So this 3-phase generator (from the manual) won't work ...</p>

Vielleicht interessierts ja den einen oder die andere, warum eine Technik, die nach alt und verstaubt klingt, möglicherweise die Zukunft in sich birgt.
