s your 602p still working now? In those days when I owned one. I found hacks to break the password and way to build unbreakable password( even by me). I miss it. And have you done experiment on the connection socket at the top? I used to keep a list of its machine code and their functions. There are about at least 32 codes and 4 memmories(2f,3f,4f) which are inaccessible from the keyboard. But I have forgetten all about these. Did u have info on it? hannyleung@hotmail.com

HANNY:

My 602p is still doing hard work for me every day. It has a 32 X 512 = 16384 steps program memory using a bank switching technique. I think I have everything you are looking for: Internal hex code, password breaking, hidden characters and codes etc. But only in printed form and in German language. If you are interested, mail me your address.

Hi,
I would very much appreciate having some of the info you have gathered about the 602 (especially about the memory extension :-)), and, even if in German I'm looking forward to getting some translation.

Thank you very much in advance,
