"I am trying to minimize the number of eP32 instructions.
My goal is to reduce the machine instructions to 16 so that
they can be encoded in 4-bit nibbles. Here is the current
instruction list: CALL, RET, IF, ELSE, NEXT, @, !, DUP, DROP,
OVER, >R, R>, AND, XOR, +, 2/. There is no room for NOP, but
it can be synthesized with DUP DROP. I think a reasonable
computer can be built with only these 16 instructions."
"My experiments now show that I need 17 instructions.
I will let people vote to have their favorite instructions

It will be followed by a discussion of the strengths and
