Here's the second attempt at creating the router monitor for project 10. The ISA bus is now hard wired to the CPU rather than over a DIL connector.
The circuit needs to be modified abit but the basic idea is the same.
And heres afew pictures of the controller
And Here's a short video showing that the CPU has correctly initalised the NE2000 and read the MAC address from the card.
The circuit diagram will follow on later.
This what the box looks like installed:
Here's the optocoupler circuit:-
And here's a short video (3Mb) showing the software in action.
