Misc. RAM Card Related Information & Problem Solutions

A //e type RAM Card makes the machine lockup...

... but when the card is removed, the machine works fine. There are two reasons why this could happen:

1)A Defective card. (Less likely)
2) The customer has a Revision A Apple //e Main Logic Board.

(More Likely)

The fix for a revision A board is, they need to get their motherboard upgraded at an Apple Dealer. This is FREE, 100% FREE, it is done at NO CHARGE to the user. They need to call their local Apple Authorized Dealer/Service Center and get the Apple //e Revision B Logic Board Upgrade.

Were Sorry, but XXXXXXX Program Requires 128K...

... and the customer bought a memory card, (for the ][+) and they still get this message. The software is looking for an Apple //e with 128K, since the ][+ is NOT a //e (We wont get into that..) The software doesn't see the memory where it wants it.

The fix for this is to buy an Apple //e, no shortcuts, no nothing. A ][+ is not a //e and the software is probably looking for the memory so it can use Double Hi-Res graphics, a feature available on the //e (Rev B & up), the Apple //c(+) and IIgs.

AppleWorks doesn't see my newly added memory...

Depending on the RAM card purchase, and the computer type, the fix for this may be either they need to run a disk that came with the card to patch AppleWorks to see the memory or card, or they may have a bad card in which case, nothing sees any memory at all.
