Apple IIc Question

[richk01@aol.com (Richk01)]

The book "Apple IIc Technical Reference Manual" says to find out what version
you have, from Applesoft you type PRINT PEEK (64447) if the value of this byte
is 255 it's the original, 0 in the Unidisk 3.5 version, and 3 in the memory
expansion version. What is it when it returns a 4 ? Does this mean there is a
later version? From looking at the motherboard it's a memory expansion version.
Any information would be appreciated.
