This would clearly distinguish boot errors from BASIC errors. Besides - I believe KERNAL can do it by itself with proper MSGFLG setting.
I think the latest ROM's are useful at this point. They have only been 
tested with VICE emulator. I have an EPROM burner and plan on doing a 
real test ASAP.
The source and ROM images can be found on
