I'd be in for two also, it sounds like it's coming along well.

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: 

slot1.jpg

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??

I started another thread in the hack section, Since its more of a project than a "Feeler"  now.
