I just recieved a used B2000-CR Rev 4.3, the previous owner had installed the 1 meg agnus chip (8372A) and he had informed me before I agreed to purchase it that he had been unable to get the chip to recognize a full 1meg chip ram. However, what he neglected to tell me was that it wouldn't recognize the system as 1/2 chip and 1/2 fast, only as 1/2 chip. I would like to either get the 1/2 fast ram working or configure it for 1meg chip ram. I had never seen the inside of an A2000 before and don't know what the procedure is in either case. There is a jumper (J500) that appears to have the entire jumper block removed (there is solder iron burns on the MB), would this have anything to do with it? I looked for other modifications on the board and I didn't notice any. There are 5 other jumpers on the board: C302, J301, J300, J200, R105 Would these have anything to do with this problem? If it makes any difference, the KickStart chip is KS V2.04 37.175, the wire that jumps between two of the pins has been removed, I remembered there was this wire on the KS upgrade I did on my old A500, and it is obvious it has been removed from this KS chip, you can still see some of the solder left on the two pins. Any suggestions? =Rick=
