regarding obtaining OS9/68K, please be aware that each issue of OS9/68K is 
specifically coded for the machine for which it was sold.

Hence I have three copies; OS9/68K personal for the Atari 1040, OS9/68K 
Professional for the SECAD AS-68K, and OS9/68K Professional for the IMS 

In all of these the OS9Boot files are quite different, although the files in 
the CMDS and SYS directories are similar making due allowance for the 
versions; (2.1 and 2.4), the rest is quite different.

For my SECAD computer, I was sent the source code for the drivers etc which 
were written by the guy who designed the computer. Sadly, neither the Atari 
nor the MM/1 versions have that.

It is in my view an enormous task to port OS9 to another platform (which the 
designer of the SECAD did) without the necessary source code to do the port.

At this moment I am endevouring to write just one driver (for an ATA IDE 
disk drive). It was an accomplishment in itself just getting the information 
required, and then writing a test programme to see which information was 
correct. That was written in 68000 assembler, as is the driver. And my 68K 
assembler is SO rusty [GRIN].

Just my $0.02
