WAITING LIST UPDATE.

I'm planning to do another run of YAZ180 finished and tested product. If you are on the waiting list hopefully I'll have something available within February 2021. If you're thinking of getting a YAZ180, I'm only planning to build enough to satisfy the wait list quantity. But you have a week or two still to register.

The YAZ180 is a modern single board computer, built on the tradition rich Zilog Z180 (Z8S180) CPU and the AMD Am9511A-1 APU. The Z180 CPU is highly compatible with the Zilog Z80, and it can run all documented Z80 instructions.

It is my attempt to create a perfect mix of "ancient" and modern computing technology. Specifically, it is an attempt to marry CPU/APU technology from 40 years ago, with modern I2C, USB, and WiFi capabilities, and make a powerful 8-bit computer that can either be embedded into an application, or operate as a stand-alone computer (with some accessories).

The YAZ180 is supported by the z88dk and it is designed to work with both traditional CP/M v2.2 applications and modern z88dk C compiled programs.

The YAZ180 is fully open hardware and open source. All documentation (Bill of Material, Layout, Photographs) and design is available from GitHub, and from my website. Some people have queried why the built price is so "high". For reference, the BOM for the YAZ180 is approximately in total US$300, comprising Digikey, eBay 1x Am9511A, eBay 9x TIL-311, SeeedStudio 160mmx100mm 4 layer 2 oz ENIG PCB, and each one takes me about 12 hours to build and test.

The included software provides yabios v2.0, two mandelbrot applications to exercise both the APU and the Z180 mlt instruction, and a CP/M v2.2 implementation supporting a FAT32 formatted IDE PATA or Compact Flash drive.

Please read the owners notes, the construction notes, and of course the readme for further information. Please read the yabios release notes to see the expected outcomes and some command examples.
