Jens Shoenfeld's anwer to the Apollo petition

In the end, everyone was free to ask him, and he was free to answer as he felt fit. All good.

I have an ACA card and the total number of games i have found incompatible on my 1200 2b are zero.
 
And i wouldn't touch an apollo card with a bargepole (I have a blizzard though)

I've had exactly one game that didn't work, but I forget the title now. Otherwise, the ACA's are what I'd call "pretty damn compatible".

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.

Gotcha. When I got my first 030/25 card, forget the manufacturer, I saw some very slight issues, so I figured there were some loss of compatibility
