HP-48G "Invalid card data"



#4

Some times ago I had the 48-G memory expanded from 32 K RAM to 256 K. It worked well.

I have not used the calc for a while and removed the batteries. Now I want to use it again and get "Invalid card data" message, which is related to the RAM expansion.

There was an init-procedure to get rid of it, but unfortunately I cannot figure out how that worked. Can anybody help?

Thanks

Hi Jan, There's a function PINIT which you will find in LEFT-SHIFT-LIBRARY then type NXT. Do this once and the memory expansion will be correctly recognised. Cheers from Switzerland Daniel

Excellent, it works without the Message again
