Re: 41CL and PPC ROM Message #4 Posted by Eric Smith on 18 Oct 2011, 1:13 a.m., in response to message #1 by Gerry Schultz
Not bugs per se, but there are problems with some of the routines if you have any "buffers" in the memory. This most commonly case occurs when using Time Module/41CX alarms, which are stored in a buffer. The buffers occupy registers just below the key assignments, and synthetic programs (including those in the PPC ROM) that manipulate the key assignments or program memory may corrupt the buffers leading to lost data or crashes.
The reason I say that these aren't bugs is that the PPC ROM was written before there were any ROMs available that used buffers, so there was no way for the programmers to know that there would be a problem.
This is an example of why HP said that if PPC put synthetics in the ROM, that HP would not accept any responsibility for the results.
