8 bit programmable computer [NO MODS]
by Gegs
NO MODS Small 8bit pc, supports sequence of 32 commands. Performs simple calculations decently fast. GUIDE: https://youtu.be/gSYSscjDRHU?si=ZqstKGYpVz5ILNuY Orange button - start computer Dark red button - stop execution Green button - confirm input Red button - confirm output 8 Green switches - input (top -> 1, bottom -> 128) Dark gray switch - open service hood each command consist of 8 bits, to write point change logic gate from and mode to or mode, Immediate number: set 00 on purple and number on first 6 bits, from top to bottom Jump: set 11 on purple bits, where to jump on green bits (computer will jump to point which is concerved in register of number you key`d in) red is a condition of jump: 000 equal 001 not equal 010 bigger 011 less or equal 100 bigger or equal 101 less 110 never 111 always Computer compares number from register 1 to register 2 Calculate: computer performs action on register 0 and number from port entered with green three bits action is determined with red input. Writes answear to register 1 Operations: 000 add 001 substract 010 multiply 011 and 100 or 101 xor 110 not (performed on second input) 111 shift (performed on 1st input, shifted by green number) To calculate enter 10 on purple, from top to bottom Move: moves number from green address to red address to move enter 01 on purple bits, from top to bottom Addresses: 000 - register 0 001 - register 1 010 - register 2 011 - register 3 100 - register 4 101 - register 5 110 - clock (only read) 111 - input (only read) / output (only write) In case of misunderstanding try contacting me, I will help you with any questions. More example scripts you can find in my workshop.
