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

[roland at rolandcruse.com]

Hi

I really apreciate the responses. I am going to bring to box to the
installfest tomorrow, open it up and anyone would be welcome to offer
comment. Hopefully I'll have enough knowledge to buy some memory after
leaving the fest.

Thanks again

Roland
