1992: Orincon DNNA

There was a startup company for a short time in San Diego called Neural Semiconductor.  I did placements for two different designs for them, but their money ran out before I could get paid.  Fortunately the key engineer there, Stan Tomlinson, went on to Orincon and carried on to produce a Digital Neural Network Architecture chip (DNNA).  They knew exactly what they wanted.  I stitched them up into a long chain with a VME interface and built them a few prototypes.  This was a stochastic chip that used logic gates to multiply and add.  It arguably could do 1.76 GFlops on this board (using AND/OR gates) equivalent to 30 i860 RISC chips.
