Characterising Am9511A-1 APU
I’ve built two hardware solutions supporting the AM9511A APU. Partly for historical enjoyment, and partly because the AM9511A is actually still faster at floating point and 32-bit long arithmetic than “modern” Z80 devices. I’ve built a Z180 based board, the YAZ180, which runs the AM9511A at 2.304MHz. And I’ve built an APU Module for the […]
