No.  You also need the CPU manual and the SCSI manuals, plus probably
some other manuals that I'm not bothering to list.  On the up side,
those manuals are lilikely easy to find.  But why start from scratch.
If you don't like linux, fine, but at least build on some existing OS.
Heck, even Akai is likely buying a third party RTOS to build their
system on top of.
