[Sylvain Rousseau]

Hi,

Mr. Merchberger had put on is website a zipped bitmap that show a quick look at how my Coco3 512KB sram upgrade should works.

Thank you Mr. Mechberger.

I will let you know if it works well when I have the chance to try it into a Coco3.

Sylvain

Perhaps if you e-mail the schematic to someone like Mark Marlette, you 
would get a second opinion on whether the design would work if there 
were no mistakes in construction.
