HI

The built in diagnostic claims 0 0 0 0 0 0 0 1

Should I understand the rightmost ram chip has to be changed ? From which point of view ?

Sometimes the test gives 0 0 0 1 1 1 1 1

Where can I buy new IIe ram chips please ?

thanks

Cyril

NS: Of course when I use the new FAstchip IIe board everything is ok since it seems the main logic is now on the Fastchip board !

Looks like $1.99 each for 64Kx1 chips in the fastest speed grade, though
you'd need to buy 16 (replace all the RAM in your 128K system!) to make
their $30 minimum.
