Need help with ZCPR33!

I am using a Tandy Model 4 at home, for which I tried to install ZCPR33.
I followed the steps in the ZCPR3 manual by Richard Conn, modified the BIOS,
made room for the ZCPR3 buffers and initialized them. The system would boot up
normally and everything was fine. After assembling ZCPR33.Z80 I was unable to
write the new system to the system tracks with SYSGEN and the computer locked
up. Then I tried to save ZCPR33.HEX to a COM-file with MLOAD and put it on the
system record directly with a small program. ZCPR33 then booted correctly, but
most of the utilities did not run, although they were properly installed.
This is true for LDR, also. Since I knew the addresses of the ZCPR33 buffers,
I could instead load the system segments via GET, which was built into the CCP.
Now ZCPR33 is working and runs ALIASES. But still most of the utilities won't.
Surprise! When I run the utilities from ZSID, they work fine!

What went wrong?

Thanks in advance, Ruediger.
