PMac Reverse engineering

PMac Reverse engineering

[Jens Ch. Restemeier]

Hi !

There are still some issues with my 5500 to write Linux drivers for,
like the (software) modem, and the I2C bus in via-cuda to access the TV
card stuff. I've been a little absent from Linux-PPC but want to fix
these sometime.

Question: Is there any usefull freeware for MacOS to reverse engineer,
what system calls an application does, and to disassemble system drivers
? Or is there somebody at apple who can be bugged to give out info ?

I have to admit that I have not the deepest knowledge of MacOS, but it
should be enough to grab some info...

Jens

P.S.: Reason ? Netscape crashes more and more, and takes the whole
system with it, and the TV application behaves quite strangely
sometimes.

I'd recommend contacting the Apple Linux guy (Kevyn, was it?) first.  xmon
at ftp://dev.linuxppc.org/users/paulus/misc/xmon.bin is very useful, and
you always have MacsBug.  They are both powerful Mac OS binary debugging
tools.

Can you find exactly who to write to ? I tried to contact one apple guy
who posted here once, to confirm my findings about the
brightness/contrast controls for the 5500 (It has a built-in monitor,
and these controls are software-driven), but didn't get a reply. ****,
it shouldn't be that difficult to give out complete documentation for
obsolete hardware... :-(
