- I didn't build it yet, but I spent a bit of time with Codeview taking
- the driver software apart. Since I already have a 75 percent finished
- PAL programmer project that can do the test vectors, all I wanted was the
- programming algorithms.
-
- I did find out a few cute things.
-
- 1. It checksums the character strings for program version and author
- and copyright and will exit if they are changed.
-
- 2. There is a undocumented command '(' which prints the version and author.
-
- 3. The 'P' program command has an added option that if you type it
- in in the form "p p c number" it programs the part from the buffer
- (as usual) and resets the "number of times programmed" information built
- into the part to whatever number you input.
-
- This applies to the version 6.51, file creation date of Feb 25, 1992.
