I bought an Apple II clone with 80-column card recently. I have some old ProDOS disks. The computer doesn't boot them, displaying something like "UNABLE TO BOOT PRODOS". Is it possible to run ProDOS on an Apple II or II+? Does it require extra memory or an upgrade of some sort? -- Andrew Bulhak acb@yoyo.cc.monash.edu.au Remember the good old days, when "spam" on the Net referred to processed meat?
