#1 · December 21, 2025, 6:44 am

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
