Getting the patch into the codebase would be the best help.  A schematic 
showing which pins you connected to the 75XXX units would also help.  I 
am embarking on a redesign of the uIEC/SD, and now's a great time to add 
the IEEE option.  I was able to find a nice source of IEEE connectors at 
a reasonable price, and I found IEEE cables at an OK price ($13.00USD is 
not great, but it's not USD$100.00, which is what I saw on some sites)

Yeah, I was not prepared to support a design that does not use bus 
drivers.  Too many failures on loaded busses.
