I wish I had an 8MB VSIMM to at least try this. Unfortunately I've yet to
salvage one (or in fact even a 4 MB). Lucky you :-)

So probably very different then, if it's only 61 KHz. In fact it's probably
a bit low for LCDs (they expect the standard one @ 67.1 KHz IIRC).

How do you set all those parameters? Is it in the PROM? (the Framebuffer
FAQ only explains this for the TGX). I don't see how to set up all those
parameters with Sol7 sg14config. If it were possible on the FFB as well it
could solve my problem :-)

Thanks & cordially,
