Thankx to Mozzerfan I now have a new A600. I put my Indivision 030, Flicker Fixer, and 1Mb Chip RAM expansion on, and aside of the extreme heat issues (which heat up even my 600 this time around), everything has been running stable.
I then installed the Subway since I have a 1200 that needed modded in order for it to work on there. The problem is that first off, the freaking Clock Port on the 1Mb expansion is WAY to close to the Flicker Fixer. In fact, as is, the cable is too high to press the Flick Fixer down far enough to not get a red screen when Booting.
So I used my dremel tool and sanded down the connector as far as possible so I could seat the Flicker Fixer. I was careful to follow the guide lines on the A603 and plugged in the cable the correct way.
After a few tries, I was able to boot up my system without issues. I installed the software that came on the CD, plugged in a few USB drives, USB Game Pads, etc. (All which work fine on my MorphOS machine) and NONE of them detected.
I gave up on this venture and continued to use my Amiga, when all of a sudden I heard a buzzing coming from inside the 600 from around where the A603 and Subway were seated. My computer then locked up and the noize continued.
Immediately I shut the system down, opened it up, and EVERYTHING was hot, A603, 030 Heat Sink, Flicker Fixer, the chips on my A600, the Subway, you name it!
I then removed the Subway, let the system cool, and rebooted and have not had problems since, though the entire system still heats up after about 20 minutes use. Ironically the info on the 030 says that it is only supposed to be Luke Warm after 1 hour of use.
What gives?
I figured I'd post here before bothering AmigaKit again, but if no one else seems to have similar experiences, then I'll make a ticket with them.
