Amiga 2000 a-model power supply (to PC supply conversion)

[arttu80]

Greetings from Finland!

I have problem with my A2000 power supply, it doesn't seem to work anymore. I know it is possible to change few little parts in it, but I wanted to try PC atx -type supply. I already installed and tried it, but my dear Amiga only flicks gray and white :-o  (with power led flickering at about 1/second rate)...

I know it must be that TICK signal, which isnt there in PC power supply..sooo, how can I bypass it? I know its quite easy on B2000 by changing jumper position, BUT on this rev 4 motherboard?!?

I will appreciate any replies!

Well, thanks for reply, but I specificly meant A2000 motherboard, there is no jumper to use internal clock?

So only option is to make TICK generator as per original PSU???
