Re: 2e enhanced ROM listing
Hi Alex,
The ROM listings in the 2e ref manual:
http://www.apple-iigs.info/doc/fichiers/appleiietechref4.pdf
appear to be for the enhanced roms:
CD : 342-0304-A (8k)
or
CF : 342-0349-B (16k)
Diagnostics at $C600 match the dissassembly.
I have a set of unenhanced roms which are completely different.

I had a quick look at the mem-test routine source, it doesn't
use any 65c02 only opcodes that I can see.
Is it always bit #5 that fails with the enhanced rom set?
Does it still fail if you disable the alternate 64k bank?

Subject: 2e enhanced ROM listing
Does anyone know if the 2e enhanced ROM listing is available anywhere?
I was able to find the original one in the 2e manual, but not the
enhanced version.
The reason I ask is that I have made a new version of the FPGApple, this
time it is a clone of the A2e. Good enough to come with good status if I
run the ROM diagnostics from the original 2e ROM. The "enhanced"
diagnostics gives "RAM 0 0 1 0 0 0 0 0" message.
Also did anyone disassemble the ROM diagnostics routines?
Thanks.
