Hi,

I have been reading

700-2331

OS-9 Addendum

----------------------------------------------------- 

Upgrade to Version 02.00.00

I thought I had it, add "LOAD CMDS/GRFO to startup.

DID NOT WORK!

With Level - II the block cursor flashes, on Level - I it does not. That 
says to me that he is right.

I did see some other things to try but I wonder if anything will work with 
VCC.

Using Level - II and disabling memory until only about what is available in 
Level - I may be my suggestion.

That's unexpected, at least we have the source for that unlike VCC (Almost).
