HP 35 with 2.02 bug

[Harald]

I have just bought an HP35 with the 2.02 bug. I haven't opened it yet, but will do so soon. Partly out of curiosity and partly because the on off switch needs lubricating. It has a reproduction label so its not too bad a thing to do. Although the reproduction label probably won't survive the procedure as well as the originals do.

Anyhow, what I was going to ask:
What else has changed with the new rom version that fixes the bug? One thing I noticed and would concider another bug is that when entering a negative exponent, chs HAS to be pressed before entering the exponent.
Is the rom code available somwhere? Id like to play with it un Tonys emulator.

Cheers,
Harald
