Re: Wico XY Pattern Generator - It's alive!

Neat stuff - I may have to get some of that stuff.

This weekend I put the vector generator to work by converging my G08.

Pictures of the test patterns posted:

At this point I'm not sure if the odd vectors / none straight vectors are
the result of a software problem (EPROM images) or a hardware problem.

It's possible the software isn't reacting well with the faster hardware (HC
logic, better opamps); but unsure.

This stuff makes desoldering a large FPGA a breeze compared to a
standard DIL 8:

Works exactly as described. I couldn't believe when I first tried it!
