Gorgeous.. Where do you find all this stuff?intric8 wrote:I pulled the megaChip and reseated it. Then I pulled that weird clip from Gary and put it back where it came from.
I read the megaChip manual, which I have, and it explains that when you install it two things must be done. First, you need to ensure you have the correct version of Agnus. Second, during the installation you actually have to cut a tracer between two points on the motherboard. So, basically, when you go megaChip, it's not easy to ever go back.
The previous owner did all of the mods and cut the board as directed. He also put the original Agnus (from 1988) in a little baggie and bought (presumably around 1990) the upgraded Agnus for the megaChip. So, I have the old Agnus, but I can't just pop it back in without soldering the motherboard.
Like you said, it's complicated.
Realistically, I have a 2nd 2000 that is functioning perfectly. The only issue it has is that it can't see its SyQuest drive. So, as each test I try continues to fail, I feel more and more like I have large collection of back-up and enhancement parts for the working one. I have extra hard drives, a floppy, an expansion card, upgraded ROM to 3.1, etc.
So, I may just migrate some things over and save the rest for whenever something ultimately fails due to old age.
I'm extremely tempted to move over the KS ROM, upgrade WB to 3.1, bring over the G-Force card (which has 16MB of RAM) and maybe see if the other SyQuest drive works. Then, whatever's left after that put into storage. That would be one rockin' 2000. It's already quite nice (2MB chip, 8MB fast) and WB 1.3 is really easy on the eyes. Since I love the early games more than the AGA, part of me wants to keep it the way it is. But I'm so used to WB 3.1 and the better UX (not the look, but just what you can do with it more easily) I may upgrade it. That's the way the previous owner's daily machine was set up. The one I'm using now was his storage/backup. I may try to bring it to his original machine's glory. I've got all the stuff.
Check out the insane monitor I have attached to the working 2000. It's a 16" Princeton Graphics monitor, which came equipped with multisync/multiscan. It's one of the very few non-Commodore 3rd party monitors that runs at native Amiga output. It's extremely nice, albeit extremely huge.
More photos of the board including the battery required.
If you have a scope or a multimeter with a frequency counter measure the DTACK pin on the 68000. Then tell me if AS is wiggling.
