Hello there,
I am working on a project which requires me to program a 12C671 chip =
through the parallel port.  I can write the program to the chip, but do =
to the 3N additional programming cycles required, the whole process =
takes about 3 minutes to write the entire memory.  Is this normal?

One thing I have noticed is that when I have my clock pulse on for less =
than 100 uSecs I start getting errors in the data.  If I go below 5 =
uSecs between rise and fall of the clock, it won't program the chip at =
all.

This my first PIC project, so I don't really know what time frames I =
should be looking for, or how best to achieve them, so any help would be =
greatly appreciated.

Thanks,
Jim M
