Special notes from the Developer!!
1. You do not have to remove the case if ONLY installing ROMX. And also, removal of the D8-F8 ROMS is not required.
2. It is possible to use the Apple Monitor to integrate individual 2K ROM files into a single 12KB chunk for programming.
3. The @@ signs during powerup and Delay setting are a bug. Developers saw this in the AppleWin emulator, but have never seen it in real hardware. Need to investigate but there should be numbers there not @ signs.
4. You wont see metadata when running the Recovery image, but they should still be there after you boot back normally (not deleted as I stated in the video). One exception, if you try to use the ROM or Disk menu before replacing the jumper. Developer will be calling this out in a future version of the manual and adding a warning for this to the program.
5. Language Card issue only applies to the (rather rare) Apple II card with F8 ROM. All of the Microsoft, Saturn, Legend etc. and clone boards do not need to be modified.
Oh, and I was wrong! Dean is from Australia. Jeff Mazur (rhymes with Lazer!) is from Los Angeles, California.
