So I recently acquired an fpga catbox to help me repair a Gravitar PCB, and decided to learn about using on a couple of spaceDuel boards. One of the boards is confirmed working and the other does not display vectors but play blind.
I hooked up the working board and it passes all the tests with no problem. When running tests on Not Working board it passes all tests up to the vector generator section and then I get some problems running traces. When running a test for
Center, draw long vectors and then halt gives me a couple of halt commands instead of VCTR in the first two commands. Somewhere I have problems with these two lines but not sure where to go from here. Any suggestions would help.
I am also trying to get signatures from the schematic but not sure where to tie the start/stop and clock lines. I am assuming that they are the same as Gravitar but some advice is appreciated.
