Jens Shoenfeld's anwer to the Apollo petition

[Zac67]

This is a pretty decent offer from Jens imho. You can't expect him to give away something for free he's paid for - and here's the offer to upgrade/replace the Machs on your Apollos.

You can't blame him for not wanting to take responsibility if he knows the design is flawed, can you? I'm sure he knows what he's talking about.

Of course, the difference between the EC020 and an 030 in itself can cause an incompatibility.

Actually, the '030 is a shrinked '020 with a (slightly simplified) MMU plus a tiny data cache. Not much of a source for incompatibilities unless you forcefully create one.
