The entire contents of my living room is currently in the room that my lab was in... while that room is redecorated and a stove is installed in place of the old gas fire.

What happens in this case where a video buffer chip is used, and the end user then whacks on a VGA adapter with a buffer chip built in (AKA: the Commodore 23 pin to 15 pin adapter) ?

Its no different to attaching a TV to the 23pin adaptor.

I did try to start workbench and it is not very happy. I managed to start it few times, but it far from stable on boot time.
I think mechanism of pushing data need to be a little bit more sophisticated like you described.

Edit: I will try with fixed 100% valid output. Maybe it crashes on software side? I may be providing date section wrong.

Do not trust the RTC test. it is as buggy as its programmer..
I am working on 1.3 that will (hopefully) have that fixed.

Do you think that bad RTC output can crash booting to Workbench?
