Working in 4-bit’s

It’s a nice challenge to program the Intel 4004 processor. All the registers and accu are 4 bit wide. So when you want to make a little delay I need at least 4 register’s to create a nice wait-delay. This hole weekend I study and work at my program with a couple of subroutine’s.


I make a lot off progress and hope I can finish next weekend the main program to run 2 or 3 challenge’s for the Roborama game’s on 5 November at the Robotica club.

Happy Programming the Intel c4004 !
