Look, I didn't know at the time. I know NOW that it's an actual 64MB module. If I could change the post title I would.

In fact, I will. Note to Mods: please change this topic's title to "LC 575 Memory Problem."

And I did do my research prior to buying. I thought this would have worked fine. It's not like the seller posted the chip numbers of the module itself on the ebay page.
