Other examples of 1-bit architectures are [[programmable logic controller]]s (PLCs), programmed in [[instruction list]] (IL).
Several early [[massively parallel]] computers used 1-bit architectures for the processors as well. Examples include the May 1983 [[Goodyear MPP]] and the 1985 [[Connection Machine]]. By using a 1-bit architecture for the individual processors a very large array (e.g. the Connection Machine had 65,536 processors) could be constructed with the chip technology available at the time. In this case the slow computation of a 1-bit processor was traded off against the large number of processors.
1-bit CPUs can now be considered obsolete; not many kinds have ever been produced, still {{as of|2021|lc=y}} some MC14500B chips are available from brokers for obsolete parts.<ref name="Digipart">{{Cite web |url=https://www.digipart.com/part/mc14500b?gclid=EAIaIQobChMIy8i09b7R5QIVT0HTCh1YgQZzEAEYAiAAEgJza_D_BwE |title=MC14500B Price & Stock |website=www.digipart.com |language=en |access-date=2021-03-29}}</ref><ref name="eBay">{{Cite web |url=https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=MC14500B&_sacat=0 |title=MC14500B |website=www.ebay.com |access-date=2019-11-04}}</ref>
