Multi-Z80 system design

Hi all,
  When going through my stash of older ICs, I identified about four complete Z80 chipsets, and
well as many perhipheral devices. For some pervese idea I have decided it would be fun to get
back into hardware and software co-design. I intend to construct a multi-z80 machine, based upon
a plane backplane, identical cpu cards, and perhipheral cards. I will also design an RTOS for
this
 or port a unix. I have most of the information I require, except for data on the Z80 DMA and
CTC. The only files I can find on the web are a two page summary from Zilog, and a large and very
broken datasheet from Farnell.

Does anybody have any (digital) copies of the datasheets I could copy?
I'll tease for now, until I have made a few more design decisions, and decided exactly how I
intend to pull this stunt off. Details to follow - should be loads of fun :)

Many thanks,

Dave.
