The Elektor 6845 runs at 2 MHz, the 6845 of the 8032 at 1 MHz. But this 1 MHz signal is fed to address line A0 of the video-RAM as well. So, just like the video RAM of the Elektor card, it outputs two bytes every micro second. 
But A0 being occupied by the 1 MHz signal, TA0 of the 6845 is connected to A1 of the RAM, Ta1 to A2 etc. etc. On the Elektor card TAx is connected to Ax. This simply meant quite some cutting and resoldering. But fortunately I received another system and now I have a spare board I can use for the operation.

But you being able to emulate a 4032, it shouldn't be that difficult to emaulate a 8032 IMHO.
