cpu from scratch?
hello, i recentlly made some cleanup in my boxes, and found all these components

Image

and now, i wonder, would it be possible to build a very simple cpu using all these fancy components..

Sure, if you've got enough of the right gates.

I tried designing a few CPU components on edge-connect cards, where they'd plug in to a backplane to make a complete processor. I overengineered them and ran out of 7400 chips, and that was the end of that.

I'd say go for it. Make a very simple CPU just a few bits wide with just a few instructions. The experience alone will be worth it.

first step, the debugger...

using 16 leds and 16 resistors, enough to see what are doing logic gates...

for the moment.

To help to create a cpu or motherboard has this one playlist from YouTube.

cool videos. working on instruction set now, 8 bits opcodes, variable length instruction.

for the moment:

8 bits cpu, 8 bits data, 8 bits adress with possibility to grow.

I will wait for the update to work with cpu.
