V1200 Led Headers

So ... I connected a simple led with two wires on the powerled header and it works. But when I connected to hdd header it doesn't do anything.

A friend of mine is looking in to a replacement led pcb based on his existing design of the original so am I missing something I should pass on ?

Depends on core you are using. If there is CF card on Vampire 1200 IDE then LED will work by triggering on LED -.

    Please hold on for a little while. I've got an adapter PCB in the works which injects the V1200 HDD activity signal into the regular HDD activity LED in addition to the signal from the mainboard.

I had to cut GND on the triple LED in between HDD and Power+Floppy of the original Case Circuit so that i now have one GND line to the Vampire for HD activity and one GND line to the Amiga Mainboard for Floppy and Power. After all it works fine.

We have worked this out with Flype for his V1200 already, I have modified the current 1200 led board (the one that i've made for Amigastore with smd leds) and add the logic to connect the ide led signal from the v1200.

Board are on fabric since 27-01-2020. Hope to receive them soon.
