I've been fiddling around with ideas for a computer in minecraft
so far I've decided on making it 12 bit, 4 bit instructions and 8 bits for addresses
no op
jump (conditional, if >0 or >=0 perhaps)
read input
display output
add
subtract
multiply
divide
read drive to memory
write memory to drive
load accumulator
save accumulator
!

also considering things like remainder, read drive to accumulator, and write accumulator to drive
not sure about them though
