The Z80 Project:

• Work In Progress.. My current tinkerings.
• Version 4 Z80 Project: A Z80-based laptop that uses a couple of small FPGAs
• Previous incarnation of the Z80 Project using CPLDs.
• Early Z80 project based on discrete logic and microcontrollers..

Utilities:

• SPILEP - A programmer for large SPI EEPROMs 25X10, 25X20, 25X40, 25X80 etc
