''Chuck Moore went on to develop a 32 bit Forth Engine called Sh-Boom, again in a gate array. The Sh-Boom chip used up to four 8 bit Forth instructions in each 32 bit memory cell, and could execute up to four Forth instructions per memory access. Sh-Boom demonstrated that a 50 MIP Forth chip could be build with very few gates on a gate array.

Patriot Scientific developed a sucessor to the original shboom.''
