What's your XT got in it now? Most non-IBM boards you could populate to 640K
anyway so there was no point in those cards. If it's got 41256 chips on it,
pull them from the card and install them in the motherboard banks, and then
set the switches properly on your XT motherboard and you should be OK.
I have an IBM XT motherboard in my 5155, so I went ahead and did the 640K
upgrade and put the chips in. It freed up a slot on my machine, so I
installed an AST RAMpage/2 in it. It's now got 2625KB of usable RAM
(Windows 3.0 loves it!)
I've done a bunch of work collecting utilities that will correct certain
issues with old hardware or enhance certain capabilities (like get rid of
snow and speed up scrolling on CGA and EGA cards, and stabilize/speedup NEC
v20 chips) Let me know if you need my help.

Subject: 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...

P.S.: Still looking for an LNW-80 Model I or Model II CPU,
and a power supply for a Laser 512 XT (like the Laser 128
Apple II Clone).
