Ram card


I have a 128K ram card (82215A). When inserting it in my 48SX, I get "Invalid Card Data". At the same time, the "Low Battery" indication comes on. I have put a new battery in the card. No difference. When I remove the card, everything seems normal.
What can be the matter?


On the SX, an easy way to "format" a RAM card is to temporarily merge it with main RAM, then unmerge (free) it again.

So if you have the card in port 1, first perform 1 MERGE ,

and after a few seconds {} 1 FREE . The brackets to the left are an empty list.



"Invalid Card Data" is the expected response, until you have data on the card. It does not indicate a bad card or other problem.
