Already in the 70s, Despain designed a chess machine as described by [[Ozalp Babaoglu]] in his Master's thesis

but never obtained funding for full construction <ref>[[Joe Condon]], [[Ken Thompson]] ('''1982'''). ''Belle Chess Hardware''. [[Advances in Computer Chess 3]], Reprinted ('''1988''') in [[Computer Chess Compendium]]</ref>.
In 1990, along with [[James Testa]], Despain co-authored on the [[Berkeley Chess Microprocessor]] (BCM) <ref>[[James Testa]], [[Alvin M. Despain]] ('''1990''').
