Semiconductor-Free 4bit CPU
This is a 4-bit CPU compatible with the CPU1738 instruction set.
This CPU uses quaternary ROM; this simulator substitutes DIP switches for the 4-pole slide switch.
Processing is heavy, so adjusting the fps is recommended.
The TD4 ramen timer program is set.
A 7-segment decoder and a ROM containing other programs are included.
Works with version 1.1.0-SR1

Very well done, thank you for sharing.
At the previous forum I also did some cpu simulations.
May I ask, did you intentionally leave out the grounded option for the Leds?
The circuit is optimized using the XOR characteristics of the LED, so this is intentional for the 7-segment display.
This CPU does not use polarized components, so it has the feature of operating even if the power supply's positive and negative terminals are connected in reverse.
