[Techtoolslist] Atari 6502A NOP adapter

[Greg Baumgratz]

That's kinda funny - that was my post.  Brings back memories...

I'll need to knock a few brain cells to remember that one.  Since it was 
my post referencing that doc I'm assuming that it is still on my drive 
somewhere, although I think there are mirrors all over the net of Al's 
archives.  I'll take a look and email you if I find it.  I eventually 
sold off my 5004, but I think I still have the NOP adapter.
