Contrary to my assertion given above, my Apple Unidisk 3.5, with controller in 
slot 7, WILL boot ProDos programs at power-up in an ENHANCED (i.e., new ROMS and6565C02) ][e. Just the 65C02 is not sufficient, since my unenhanced ][e, with a AE Transward (which supplies a 65C02) in slot 3, requires a PR#7 to boot from   the 3.5 controller in its slot 7.
