thomas scherrer z80 family official support page official support page hardware software utilities faq docs for z80 family last updated august 2026 the purpose of this page and its sub pages about members of z80 family and close relatives is to collect and share information and good ideas i know there are lots of people out there who have developed some good utilities and hardware solutions now we all can share this infomation this page contain docs faqs source code cross assemblers cross compilers utilities etc as well as links to other z80 relevant stuff some of the info found here is property of zilog like hardware docs instruction sets and some of the software available read the copyright notice if you know an url matching the subject of this www page tell me and give recommendations where to place best some of the links here are no more online and some are not yet correct they are marked with a sequence in case you know the appropriate url i m ready for an update please report all updates corrections and suggestions to the webmaster gaby chaudry be aware of the fact that many products mentioned in this series of z80 related documents are nowadays out of production if you want to start a project don t forget to check where to get the parts from and what the conditions are yes i have read the legal info information about our data privacy policy according to the german federal data protection act bdsg breaking news sharp has built a z80 cpu on glass learn more about it in their press release z80 8 bit cpu formed on glass substrate zmob a new computing engine for ai multiprocessor computer with 256 z80 cpus see also zmob technical report university of maryland computer science technical report series important information z80 product line z84c00 end of life last time buy notification the z80 is dead long live the free z80 z80 replacement reaches silicon a community driven project has produced working silicon for an open source replacement of the classic z80 processor new implementations picoz80 the picoz80 continues the tranzputer theme replacing a physical z80 in a host or industrial computer with a faster cpu more memory virtual devices networking wifi bt rapid application loading from sd card and wifi management unic the modern way to z80 and more this work aims at replacing almost any 40 pin dip package chip from
