ATnoX: ATX power supplies for Amiga (update)
The Amiga 1000 (and, depending on additional hardware usage, also the Amiga 2000 and 3000) require a so-called tick signal not provided by ATX power supplies. It is a 50 or 60-Hz reference signal for the video chipset. ATnoX is an open source board for using ATX power supplies on the Amiga which adds this signal.
Update: (06:52, 15.10.20, snx)
Additional information regarding the Amiga 2000 and 3000. Both mainboards can be configured to generate the tick signal from the clock rate instead (like those Amiga models with integrated keyboard do). This jumper setting reduces accuracy, though. Thus for certain applications, e.g. genlock usage, also these big box Amigas do require a power supply providing the tick signal. (snx) (Translation: dr)
