DC expansion port

[Splynncryth]

I can't seem to get any detailed information on this thing since bitmaster's site is gone. I'd like some detailed info on it like bit width and clock speed. I want to *somthing* with this port eventally (probally after I finish my EE degree real soon now) but I don't know what will be possible without info on it.

BTW, anyone have any experience with DSPs?Another long, drawn out side project has been to eventally bild somthing to deal with GD-ROMs. The docs I have for some Phillips hardware outline the archetecture for a writer and reader. They have a DSP dealing with the signal from the pickup and it does a lot of the magic.
