Please...be more specific! If the ROM in a 512KE is the same as a Plus (I have the 'Lonely Heifer' ROMs, along with the vast majority of Pluses) how are "address lines brought to the ROM" or any other kind of addressing "different"??? --given that the 512KE has been upgraded to >= 1MB. OK, the clock chip has more parameter RAM, and 6.0's Sound Manager uses it. So why does it work fine on MY machine, which is a 2MB 512KE without the MacPlus logic board/clock chip??? The only thing I can think of is perhaps I have a "magic combination" of patched traps from all those INITs in my System Folder. This would then imply that (as David O'Rourke suggested) it would be possible to patch something for 6.0 to run on a 512KE w/1 meg or greater. I still have my DB-9 serial ports. And they're working great with 6.0. Again, here's my setup: Mac 512K with disk drive/ROM upgrade and 2 meg Dove MacSnap upgrade, Dove SCSI port/daughter board, Jasmine DD20 HD, Apple 800K external floppy drive, original ("classic") keyboard & mouse. It may sound odd, but WHAT AM I DOING RIGHT?
