Title: Amiga A1222 Plus Tabor Specifications: "WCU Prog" and "CPU LED Port"?
Post by: First Ninja on April 28, 2020, 03:45:24 PM
On the official Amiga 1222 Plus product page (http://www.a1222plus.com/?page=about), there are a couple of peculiar entries:

I've not heard of this before either but the port has six pins and there also a load of diagnostic lights clustered around the SATA ports labeled as WCU LEDS.

  • Why does the CPU have its own LED port? What purpose does it serve?

It only has  2 pin header so I assume it's a crude CPU activity indicator.

i think the WCU prog thing is a typo.
There is a header called MCU prog on the board, can't remember seeing anything called WCU prog.

Are you sure that header is really called MCU? Judging by the photo Rob refers to, it might just as well say WCU? Here's a closeup:

Got it. Do you have any idea what triggers the signal, and if its digital or analog?
