<That sounds interesting. How much of that is just instruction set? If

The instruction set is some 48 instructions and most are real simple.

to make a sim you need timing, instruction set functions and a few trivial
details. one thing, write in something like interpreted pascal, the 8008
was slow as the fast part did a register to register move in a whopping
10.8 microseconds. To give an idea of how slow that is the 8080 did it
in 2 us, z80/4mhz in 1us, 8048 2.5us, 8051/11mhz 1us, 8088/5mhz 1us.
The 8008 was slow!
