Have received an A2000 with scsi card and 2030 turboboard, but it didn't boot up. Only get black screen without any colours, so it means that da processor might be crashed. So I opened up an old A500, removed da processor and then opened up da A2000. But, and now comes the problem, this computer has got a MiniMegaChip that gives it 2 Mb chip memory. In real life this means that an A2000 chip is placed onto a little board that is inserted onto the motherboard, but also a black wire that is connected to two pins of the processor, somewhere in da middle of the processor. So now it becomes complicated. Is da processor malfunctionning or is it that MiniMegaChip with its black wire that is causing the problems ? I don't wanna damage anything so I ask it here to get useful information.
I still wanna use that A2000 to insert an X-Surf and a CV64/3D so don't tell me that it's old stuff and that I need to get rid of it. It may be slower than my A4000 and towered A1200 with Z4, but it's still a great machine that only doesn't have AGA or da possibility to insert PowerPC cards, that's all !!
So please, if somebody has got experience with my problem then please help me out !!! This is da first A2000 I ever have and I wanna keep it !!
As per another suggestion here, I'd strip the machine of all the third-party addons, including the '030 board AND the Megachip. Take careful note of where that black wire clips on. The Agnus chip out of your A500 will easily replace the Megachip and drop the machine back to it's standard configuration.
From there, start adding things back in, checking that the machine boots properly at each step.
I have several A2000s, but the main machine sports a Blizzard2060 w/ 32MB, X-Surf, extra Oktagon SCSI card and 2032 (Amber) Flickerfixer. A great workhorse that's run 24/7 for the last 8 years. :-o
