Subject: ZCPR for RS Model 4

I'm seeking advice on installing ZCPR3 (and possibly ZRDOS) on my TRS-80
Model 4.  To date I cannot find the correct components to install these
enhancements.
 
SYSTEM CONFIGURATION
 
I'm currently operating a TRS-80 Model 4 with 128k memory expansion 
installed, two external 5 1/4 in. SS/DD floppy drives and a Radio
Shack 5-Meg hard disk drive.  
 
Software:            Serial:              Comment:
CP/M 2.2             #CP2-1040-003828     Used MOVCPM.COM to create a
                                          63k system, allowing 1k to
                                          install hard disk driver.
 
HDRS5M.COM           #HDD-OU81-002626     Hard disk driver, also from
                                          Montezuma Micro.
 
Have some additional fee-software, ie. Montys Window and SYS2M that
reside in the ramdisk and will require additional "bit-fiddling" later
on if I'm going to continue to use them.  They make unadvertised use of
some addresses in the BIOS not previously claimed by DRI.
 
Biggest problem with the installation of ZCPR3 is that I do not have an
assembly language copy of the BIOS in order to create file CBIOSZ.ASM
required for the installation.  
 
Any information on getting ZCPR3 up and running on the above system will
be greatly appreciated.
