As I remember it, Basic 1.0 used jumpblocks in ram so that the rom could be altered in the future without causing incompatibilities with software, so if some programs did not work with basic 1.1 it must be because the programmers did not use the jumpblocks in ram, so it is unfair to say that basic 1.1 caused incompatibilities with existing software.

Well Steve, as mentioned before parts of these "jump blocks in RAM" have been modified. As suggested take a look at the CPC ROM Listing published by Markt & Technik or similar literature, f.e. firmware guide.

The hardware of the 464 / 664 and 6128 is actually way more compatible than its native OS or BASIC.

And btw. don't think that BASIC 1.1 on 664 is that same as on 6128.

 That's why Amstrad was so outspoken about sticking to the firmware after all, wasn't it?

I second that. (Just to put in my weight. *cough**cough*)

BASIC 1.1 on the 664 and 6128 are definitely different.

You can even make a Forth, C, or Modula 2 machine out of the CPC. There are no borders left if the lower ROM can be replaced.

But the pitfall here is... for a new OS you need also a bunch of Apps.
