Cracking the code. WPC-DCS update.

About one month ago, I posted a note about my successful reproduction
of the WPC-DCS system using a Xilinx FPGA. Since then, I have been
working on the more difficult task of doing the same with the WPC-95 A/
V board. As you all know, this board uses an ASIC, and its complexity
makes the job of reverse engineering it more difficult. I am pleased
to announce that this effort has been successful.

Details here:

If there is demand in the future, I may be making a unified WPC-DCS
and 95 board available in cooperation with Jim Knight. This would
allow use in any DCS machine, and you would load the ROM content with
a cable. No burning of ROMs needed.

Impressive! Reminds me of when I reverse engineered the switch matrix,
though that's not nearly as difficult.

Good work!

Hey Ed - Figuring out how to get a man to Mars and back isn't enough
of a challenge for you? Sheesh..... You need a hobby, brother! ;-)

Sweet, I heard from Jim that you guys were working on this. He told me
the WPC 95 AV boards could be ready possibly be January.

Wow, sign me up.
When do you have time for this ? I know you are busy working on the
teleportation device ?

I think the best replacement would be to install a chime box instead!
