James, thanks for the offer. I still have some work to do before I
release it to my web page. Last night I `locked-down' the CPLD pins to
facilitate routing. That completes the CPLD core logic. I still need to
generate documentation and an overall schematic with suggested PIC and PC
parallel port connections.

   As far as software, I want this to be primarily a PIC project that
provides a serial interface between a PC host. While the PC work can be
moved to a web-based discussion, I want the PIC work to remain in this group
so others can share in it. On the PC side, the GUI can easily be designed to
support both a parallel or serial interface and that will be a separate
effort.

   The host interface is the same as I described in my recent message. I
have added 2 external triggers to better support a DSO but that does'nt
affect the software. Once I post the design on my web page we can start
getting into the software issues in detail.

   In the mean time, you may want to check my web page for a simple
programmer that allows you to program the Lattice devices. It can be built
for around free to $20 depending on what you have laying around. There's
also a link to Lattice where you will need to download the free ISP download
sotware. Note, there's also a 24-Bit trigger comparator but that's not the
version used in the logic analyzer. For more info:
