This article presents a transistor level schematic of a data bit’s gate which I reverse-engineered from a die photograph. The Anatomy of a Z80 Gateĭata bus on the Z80 processor carrying information within the chip itself do not simply connect to package pins and out to the world - the gate circuitry of each bit is quite complex.

This set of articles describe its design and implementation.Īnd OpenCores: Sinclair ZX Spectrum on the A-Z80 CPU It differs from existing Z80 implementations in that it is designed from the ground-up through the schematics and low-level gates. A Z80 From the Ground UpĪ-Z80 is a conceptual implementation of the venerable Zilog Z80 processor targeted to synthesize and run on a modern FPGA device. This article contains a brief overview and introduction to the A-Z80 CPU created for FPGA and a ZX Spectrum implementation tied to it. Open source project is at GitHub: and a brief overview on YouTube The A-Z80 CPU

Z80 Explorer is a Zilog Z80 netlist-level simulator capable of running Z80 machine code and also an educational tool with features that help reverse engineer and understand this chip better. NEW Added code to print to an HP 82240 printer! See it on YouTube.

The calculator is complete and running!ĭemo is on YouTube, and a WebAssembly runnable version is here.

Practical Numerical Methods, more advanced algorithms.

With a weak internet over a phone data line, I could only do some preliminary searches and mainly work out various details on a writing pad, growing a feeling that the project may be personally exciting and practically doable. The idea for this project came about during a week of freezing winter arctic event here in Austin, Texas, with a failed power grid as well as government, while keeping close to a gas fireplace, the only source of heat and light, for a couple of days.
