I finally sat down and started to debug my Apple-1 BASIC firmware card. I had never played with the Pom1 emulator, so I downloaded the C source code and after about an hour I had it running in xCode. The image below, shows the emulator running the same BASIC ROM file that I had burned into my EPROM chip. You can see, it does not show the ">" prompt as it should.
This is the apple1basic.bin file, which I downloaded many months ago from www.pagetable.com. This is the same output I was seeing with my BASIC firmware card. (At this point, you must do a reset, as BASIC fails to load).
The above 2 images show the hex and decimal locations of the 2 incorrect bytes found in apple1basic.bin
