The files in this directory:

customize.hcx	the IP address customizer, creates "Customization Values"
tftp.hcx	the tftp program itself
mpp.hcx		the 'mac protocol package' inserted in the system resource


Use 'binhex' to convert the hcx files to resources.

I am not sure what version MPP this is, but it is the one that is
compatible with Mark's code.  I suggest you start with a 'default'
system resource with no fancy desk accessories or ramdisks.
Use the Resource Editor to 'copy' the resources into 'system'.
The resources are:

INIT	6	installs the mpp driver at boot time
DRVR	9	mpp driver
DRVR	10	atp driver

You shouldnt have any ID collisions if you started with a vanilla 'system'.
