A2058 Problem

[dougal]

I want to work out if the problem is with my Amiga or with the A2058 ram expansion.

Amiga is a Rev4 A2000 with kickstart 2.04. 512K Chip ram.

No other zorro cards.

WIth the A2058 (populated with 2mb) 90% of the time the A2000 refuses to boot. It just gives the first grey screen and then either stays like that or else crashes.

If i set it to 4MB or 8MB it gives the error of the autoconfig board.

If i disable the amiga works fine but obviously with only 512K.

The card looks good, caps look good and the edge connector is clean. I cleaned it myself to make sure and even cleaned the zorro slots using an electronics cleaner.

Tried all zorro slots. Same problem.

I am buying a GVP Scsi controller with 8MB, so i dont really care for the A2058 as such but i hope the a2000 is fine.

Yep i'm thinking its the ram chips too. Unfortunately they are soldered.

I would boot up to test but it barely ever boots with the 2MB enabled. More like maybe 1 in 20 or 50 times.

I also think its the ram because without the card the amiga boots fine and if i set the ram card at a ram it does not have (4mb or 8mb) the amiga boots to the expansions screen of kickstart 2.x with a red color indicating a bad board.

So i believe the zorro slots are probably working fine.
