In particular, this seems very useful and to be a part of a larger document which I have however not been able to find online.
Looking in that same directory at all the PDF files, I found this doc which seems to be part of the same set: http://hcs64.com/files/RDP_COMMANDS
I too would love to see the full set of docs, good luck with your search =D
Here is another useful unofficial doc from Dragon Minded: http://www.dragonminded.com/n64dev/Reality%20Coprocessor
BTW I have noticed a mistake in every single official/unofficial N64 doc I have ever come across:
The RDP opcode "Sync Load" is always stated as hex command "0x31" but the command portion is actually meant to be "0x26"!!
For completeness here is a list of every Nintendo patent I have found in relation to the N64 (This includes doubles):
