According to the Apple IIc Technical Reference Manual only the original IIc
did not support the UniDisk 3.5" drive. To find out which model you have Peek
memory location 64447 (from BASIC type ? PEEK(64447)). If it returns 255 then
you have an original IIc ROM which will not support the UniDisk 3.5" drive. A
0 indicates a IIc with the UniDisk ROMs, and a 3 indicates a memory expansion
IIc (which also supports the UniDisk).
