my CPLD development board came in today. Cool little thing. Now just waiting on the JTAG. 

better start working on the PCB layout, but I need to come up with a footprint/pin for that RAM IC in eagle. 

Last thing is ordering the buffer ICs.

Guys, I have a discrepancy here. 

Designing cards and drivers for macintosh, and the original portable developer notes list the slot like this:

but... 

Guide to the macintosh family hardware lists the slot like this: 

slot2.jpg

The pinouts between the two are very different. (same signals though)..

any thoughts??
