After reading the news about the new CoCo 3 I went to Radio Shack for more information. They gave me a nice sales brochure and let me look thru the new catalog. In the new catalog Level II os9 was listed with a price tag of $79. The combination of the new CoCo aand Level II os9 is too much for me to resist and I hope to buy both as soon as they are available. My only concern is if my os9 Level I C and Pascal compilers will work with os9 Level II. Does anyone know if I will be able to use my old compilers with Level II? Can I buy an upgrade ? Or will I have to buy new compilers to use with Level II os9 ? Larry Harmon

It works on Level One or Two (There is another version for the 68K of course). The Microware distribution of the C compiler includes two versions. The level one version sacrifices speed for size. It has one more pass than the level two version. However, if you want, you can run the level one version on a level two system. I had to do that for some forgotten reason when I first got my C compiler. As a rule all programs that run under level one will run under level two and vice versa. The exceptions to this rule are programs that use the additional SVCs available under level two, and level one programs that reference addresses than won't be in their address space under level two. ... One other exception: some programs need the full 64k - delta address space available under level two. The level two C compiler is an example. Peter Dibble

There's no problem with the C Compiler. the only difference is that the first and second passes are in one module on the Level II version of the compiler. The passes were separated in Level I to fit in the smaller RAM space. I'm not sure about the Pascal offhand. I *think* it's ok too.
