[Coco] CoCoSDC Issue

[neil at neilscomputerservice.com]

Hi Darren & Ed,
 
I am using the CoCoSDC on my CoCo3 With 512K Triad. It will load games such as
Nick's Pacman & Donkey Kong however it will not load
Z89, Those Darn Marbles, Contras and any other ones with non-standard disk
routines (copy protection). Now if I take the exact same SD memory card
out and put it into my other CoCoSDC that Darren built and sent to me it works
perfectly on my same CoCo 3 setup.
 
To be honest after I assembled the card I accidently left the jumper on "AUTO".
So I am wondering if that may or could have damaged something? Or could it be I
have
a bad trace somewhere? Not sure if that is possible considering everything else
works on it.
 
Thanks,
Neil
