One of the first boards I'll get made next year: The A500 r.3 is almost ready, but, with case closed, I have no way to monitor IDE activity. This board just injects it into the floppy led.

It's really nothing special, nor a new idea at that. It just replicates the same circuit that the A500 uses for the MTR0 signal to light the led up and puts itself in parallel to that.

Ok, finally built the injector and wired it up to pin 39 of the IDE connector on the accelerator!

And it works!

Don't mind the "Plus" on the badge, it's very much not so, as this is a junked case that I found together with this A500 rev.3

It looks a bit better using angled headers.

@hkz I've been meaning to put something like that together for my A500, I really need to reorganise a bit so I can have it set up and running more often ...

@mike space and organization are quite a problem for me too. I usually pull things out of storage on rotation.

When you do, member to post pics! I'm always looking for ideas and inspiration!
