Ok, first of all, the PPS 2000-040 is a very nice 040 board ( I have 2 of them ). Make sure that the Kickstart in your Amiga 2000 is 2.04 and that you are using either Workbench 2.04 or 2.1. The PPS 2000-040 board does not work properly with Kickstart / Workbench 3.x. The board requires at least 4 megs of ram installed to work. The memory are 30-pin SIMMs 1 meg or 4 meg non-parity (2 or 8 chips). 3 chip or 9 chip (pc) SIMMS will not work properly. The best SIMMs to use are out of old Macintoch computers. The jumpers on the top of the board must be set correctly. You will need the manual for this or I can tell you how to set them.
Looks like there is corrosion in the 68000 socket. So, it should be replaced.
After unsoldering the battery (do not rock it or break it free), clean the board with 99% IA and 100% cotton pads. Do not use anything else.
Check inside the processor slot with a flashlight. Make sure that all of the contacts are shiny. If some are dull, then the processor slot will have to be replaced. Leaking batteries can "pop" or "splash" their corrosive paste to nearby areas of the board.
