over the last week or two i have managed to find thi site. did a little research, contacted wjohn. bought a grinch board and 8 ssr boards from him. as part of this i managed to get 2 MBI chips and the various other parts.
I have managed to build the grinch and today have started testing to see if i can hook it up/
with only 2 MBI chips i can only use the first 32 channels.
i hav made a small LED board for testing so i can see the channels turn off and on.
Checked the LPT port settings and it is set to ECP + EPP in the bios ( no EPP only option.) under windows it see's it as a ECP port.
what im finding is if i turn ALL channels on or off any of the channels work fine. if i try and turn 1 channel at a time, i get random results.
Am i seeing an issue because i only have the 2 MBI chips installed or has this been tested b4. also i have tested with 1 chip and get the same result.
I have tried both the v1 and v2 vixen with the same result.
does anyone have any thoughts?
