That's not right. (I think.)  The model IV has model III roms inside the
machine.  The model IVP does not have these roms and therefore needs to 
read the rom image (MODELA/III) off the disk.

By the way, hold down the break key when powering on the IV and
you will go into model III "cassette" mode.
