I would avoid messing with anything else and just go source a motherboard. The risk is that you will damage a component of something that is way more valuable. Amiga 1200 motherboards are really ten a penny compared to some of your other kit... Thinking about the Blizzard mostly.
I have problems with one of my towers which I put down to it standing vertical in the case, cus with just the odd nudge it will come back to life. The things junk so I really am not that bothered. Just funny giving it the old BSA treatment to get the thing working.
Sorry... didn't read the last post. Good luck.
