The systems named, TX-0 and TX-2, tweaked my recollection of items I&#x27;d seen while cataloging at CHM. There are a number of items related to the TX-0[1] including a picture[2] but also quite a number of its unique circuit modules[3], which were small plastic cylinders with 7-pin bases. Each cylinder held a couple of transistors and other components, approximating one gate per &quot;bottle&quot;.<p>CHM also has a quantity of TX-2 items[4] such as this picture[5] and numerous of its circuit modules[6], which were narrow 2&quot;x6.5&quot; circuit boards.<p>[1] <a href="http:&#x2F;&#x2F;www.computerhistory.org&#x2F;collections&#x2F;search&#x2F;?s=tx-0" rel="nofollow">http:&#x2F;&#x2F;www.computerhistory.org&#x2F;collections&#x2F;search&#x2F;?s=tx-0</a><p>[2] <a href="http:&#x2F;&#x2F;www.computerhistory.org&#x2F;collections&#x2F;catalog&#x2F;102630740" rel="nofollow">http:&#x2F;&#x2F;www.computerhistory.org&#x2F;collections&#x2F;catalog&#x2F;102630740</a><p>[3] <a href="http:&#x2F;&#x2F;www.computerhistory.org&#x2F;collections&#x2F;catalog&#x2F;102733906" rel="nofollow">http:&#x2F;&#x2F;www.computerhistory.org&#x2F;collections&#x2F;catalog&#x2F;102733906</a><p>[4] <a href="http:&#x2F;&#x2F;www.computerhistory.org&#x2F;collections&#x2F;search&#x2F;?s=tx-2" rel="nofollow">http:&#x2F;&#x2F;www.computerhistory.org&#x2F;collections&#x2F;search&#x2F;?s=tx-2</a><p>[5] <a href="http:&#x2F;&#x2F;www.computerhistory.org&#x2F;collections&#x2F;catalog&#x2F;102622491" rel="nofollow">http:&#x2F;&#x2F;www.computerhistory.org&#x2F;collections&#x2F;catalog&#x2F;102622491</a><p>[6] <a href="http:&#x2F;&#x2F;www.computerhistory.org&#x2F;collections&#x2F;catalog&#x2F;102677413" rel="nofollow">http:&#x2F;&#x2F;www.computerhistory.org&#x2F;collections&#x2F;catalog&#x2F;102677413</a>
