Wow, this is an incredible blow by blow tutorial in a lot of ways - thanks DonutKing!
The more I learn about this board though, seems more and more features were never finished or implemented. The direct use of the 8375 is a let down for sure, but I bet the DKB MegaChip and equivs would work.

Haven't read every single detail, but have you managed to get the SCSI portion working yet?
Oh, and I've read were, if you fill all of those Kickstart sockets in, certain fat floppy drives no longer fit? You have to mount a slimmer floppy drive instead?
