Hello. I have a German Apple IIe unenhanced.I wonder if I can change the CPU with a 65C02 and burn new roms (or eproms) with new enhanced firmware.Perhaps has someone the images of the three needed roms? What about German characters? Do I loose them if I change the three roms?Are there any incompatibilities with old software running on Dos 3.3 if I make the Apple enhanced?
Martin covered the compatibility issue. Give it a try, if there is a critical program that won't run on an enhanced IIe then you can always change back. Since you aren't changing the keyboard ROM I believe you'll retain your German characters. When the enhanced IIe came out, a lot of people did the upgrade by bying a 65C02 and copying the ROMs. Quite a few edied the ROMs so their own name showed up on the startup screen. http://www3.telus.net/waynes/enhanced.cd.zip http://www3.telus.net/waynes/enhanced.ef.zip http://www3.telus.net/waynes/enhanced0265.zip
