Amiga 3000 Jumper Settings

[Kernel]

Can someone direct me as to how to read the A3000 jumper settings?  They seem to have an arrow around them but I'm not sure which end is actually pin #1 - the one at the back end of the arrow, or where it is pointing?

Also, I have a rev 6.1 motherboard with the 1.4 roms, but the system has a 68882 which to me means it is a 25MHz machine, yet sysinfo indicates otherwise.  About .78 of a 25MHz if I remember correctly.

Can someone point me in the direction on how to make sure the board jumbers are set properly?  I see stuff on the net, but I'm looking for a quick answer now and will delve deeper later tonight.

Thanks.

Here is an image of the battery area after removal of the leaking battery.  Anyone care to comment on the damage - do I need to do anything other then the cleaning with Alcohol I gave it?



Here are images of the CPU and MMU indicating they are 25MHz, yet SYSINFO reports less than that.





Here is an image of the 1.4 ROMS.  One of the labels came off (glue death) during cleanig of the mobo and exposed the programmable wafers... I hope the light didn't hurt it.



And lastly, here is an image of the underside of the board.  It looks like something was spilled on it at some point; I cleaned as much as I could, but there is still a film on it.  I can only call it "grunge"... anyone know what it is or if I need to worry about it?

Pics were taken at highest resolution on a Kodak digital camera (forgot exact model) and then resized in ACDSee and clipped to the area that I wanted to post.

The system has 4MB of FAST RAM... I am guessing that the A3000 in SYSINFO specs is a fully decked 18MB system, since I used to have one and it was 1.00 instead of the .77 I am getting - and it reports "Cook That RAM!".
