The instruction sets weren't similar, they was identical. The Intel 8008
(and TI TMX1795) were designed based on specifications from Computer
Terminal Corporation, maker of the Datapoint brand. CTC chose not to use
either chip in the Datapoint 2200 family, though.
The 8008 instruction set is basically the 8080 instruction set with the
best instructions removed and the opcodes reassigned.
