Need Docs for XT RAM Board...

A friend gave me a Magitronic XT RAM Card. It's an 8-bit ISA Full length card with 8 sets of 9 sockets. It's totally unpopulated. It has 8 position DIP Switch. Currently all but #5 are off. It has two Magitronic Stickers. One has the number 606 and the other 0687 I'm assuming this board populates with 4116 chips for a total of 128k or 4164 chips for a total of 512k I have an original XT board with 256k on it and I want to take it up to 640k total. I'm hoping I can put 4 sets of 4116 and 4 sets of 4164 on here for 384k. So, any help with a copy of the manual or link to the same would be much appreciated. I have an Oak 8 Bit VGA card in the XT that not only handles VGA but also does EGA/CGA/MGA/MDA. I have a couple of these cards, and they are like gold to me. I'm looking out for a high density disk controller for an XT so I can put one 1.44mb drive on it for data transfer. But, it will be fun to run an XT again...
