Maybe you can look at it this way: The video controller of the Q60 
squeezes _more_ functionality than a contemporary Lattice reference 
design, into a PLD with less than _half_ the resources. This came 
not only from manual optimization using every possible trick, but 
also at the cost of flexibility. I had to exploit constraints that 
are not given at 800 x 600. I clearly remember that I tried hard to 
implement 800x600 some time after flatscreens came up, and came to 
the conclusion there is absolutely no chance.

Thanks for clarification. If the OSSC wasn't such an expensive, 
clumsy setup, I would also just say: Issue solved. Period.

It's very good that you published your experience - I would never 
spend the money without knowing that it actually works with the Q60. 
For the BBQL, I have a better HDMI solution, so I have no other use 
for an OSSC. If it has not happened yet, I would encourage you to 
post your result on the QL forum also.

Or a different board that would run with the 68060 pulled out of the 
Q60, hence my original question.

Of course. And also smaller, nicer, decently cased. If not for time 
shortage _plus_ other priorities even for the QL hobby, that would 
be an intersting project.
