[Leaplist] how much memory can my 1G motherboard hold?

[roland at rolandcruse.com]

Hi Leaplist

I am looking to put more memory into my 1G motherboard which has three
slots. Looking at the chips on the board shows SDRAM 133mhz chips. Right
now it has two 126 SDRAMS and one 256. I am wondering if someone with more
experience can help me what is the most memory I can put in. Below are the
specs I picked up from the motherboard on the Internet. I do not know if
that is enough.

Thanks for any help.
