AS Level - H065 Content Checklist


EZ-CPU SYSTEM

For A-LEVEL control module.

Z80 programming made easy!

The EZ-CPU system has been developed to assist with the A2 Control module. This system has been developed by teachers and tested with great success.

There is support material available, used in the very successful delivery of this module.

FREE SOFTWARE
AVAILABLE

Specially written software to the EZCPU system. Download/upload files and write programs using the virtual EZCPU

There is a range of material from exams to circuit examples, grouped in unit order.

Material is being added all the time so please click Refresh a couple of times when visiting this page again.
