Looking for switch and jumper settings for AST MegaPlus (not the MegaPlus II)

[wrljet]

This is a MegaPlus Rev B, not the MegaPlus II (specs for which I found on the web).

Anybody have the switch and jumper info?

Restoring a 64k motherboard 5150 and it's got one of these in it.

Thanks,
Bill

Yeah, I saw that one. Mine's a Rev B and doesn't have the same layout as that board.

I have figured out the switch block settings for the memory on this card, and I will
post those soon after I get them typed in some decent format. The card can provide High DOS memory.

I also found and replaced a couple bad RAM chips on the daughter card.
So it's working nicely now.

One of the bad DRAMs had something that looks like it came out of the chip, between pins 3 and 4.
It's copper colored, and is flexible. I asked a friend of mine who's worked in the IC industry for decades and he had no idea what it was.

Here's a picture of that one chip, and the board:
