4-bit Homebrew CPU - counting test

[ravingidiot]

Using a LUT for performing addition is a nifty design decision hadn't considered. What influenced your decision to use this implementation?

[buzbee1]

Nicely done. How about a link to schematics and more detail?

[256byteram]

@buzbee1 yes, there's a link in the description now.

That's a remarkably-low discrete TTL chip count, given that it contains 16-bit wide CPU registers :-) Awesome work!

[vk2zay]

Awesome. Trust me, your desk is not a mess!

[LunaVorax]

This really is awesome, but what is the use of it?

[Esperantanaso]

That is a neat idea to make a 4 bit computer operate on a large amount of RAM. Why were some of the segments in the display not lit for certain numbers?

[Dropshock0]

@Esperantanaso He said in the description that there are two blown segments on the LED display.

[Desmaad]

What was that crackling sound I heard at the beginning of the 1KHz segment?

[256byteram]

@Desmaad Probably me connecting the mains to the ATX power supply
