Linux friendly motherboard for intel i5 6600K

I remember the PCB instruction for Honeywell Easycoder, can't remember the BAL equivalent, but pcb was peripheral control and branch instruction, and machine code was:

Output:
65 01 00 52 64 01 31 ... (... were the options) Octal
65 was the pcb op code, 0100 was the buffer address 52 was the channel 64 had something to do with action taken if busy can't remember the rest

This was coded in through rectangular buttons on the front of the computer which lit up when pressed, they were in groups of three for each octal digit, and in three rows, instruction address, data address, and memory. I could punch in a rather long program like playing a musical instrument. The time it took wasn't a concern as the only other way to do it was to punch up a bunch of 80 column cards and read them in, still requiring a manually entered bootstrap.
