MikroLeo is a discrete TTL logic-based microcomputer intended for educational purposes created by [Edson Junior Acordi], an Electronics Professor at the Brazilian Federal Institute of Paraná, Brazil.

What we are going to do is design a simple 4-bit computer at the primitive logic gate and flip-flop level and then implement it in the technology of our choice I’ve often wondered what would happen if ...

[Agp.cooper] saw a vintage 4Kx4 bit RAM chip and decided that it needed a CPU design to match. The TTL design fits on two boards and has a functional front panel. This custom CPU project has a few ...

How would we handle metastability in our 4-bit computer if we were to implement it as a microcontroller chip, a single-board computer, or a cabinet-based system? Now, after laying all of this ...

In 1971, Intel Corp. introduced its first microprocessor chip, the 4004. The 4-bit processor chugged along at a mere 104 KHz. In the 35 years since then, processor clock speeds—and performance—have ...
