Restarting Old Amiga's

Looks like my Commodore 2002 monitor needs work. It?s not powering on. However, a monitor that is about the same (says Amiga on the front), seems to more or less work. The A500 (KS1.2) and A600HD (KS2.0) both complain they need a boot disk. One slight problem, I have no idea where any of my Amiga floppies are. Thankfully the Gotek I have was purchased pre-flashed with the old Cortex firmware, and as a result I was able to boot my A600HD before calling it a day last night. Figuring out how to use the Gotek proved to be an interesting experience, as either my google-fu is faulty, or information online is pretty spotty. Once I got it going, it seemed to work fine. The A600 is going to take a lot of work, and it looks like a couple parts to get it fully up and running. Since it?s a A600HD, I?d like some sort of HD in there. Zane
