What does the OSSC do then... a) scale 512 to 480 vertical pixels? b) somehow make the monitor display a 512 pixel signal? c) just output 480 pixels, and 32 lines are lost? >> I have been generating 1024x768 @ 60 Hz DVI/HDMI directly from $5 FPGA >> with only moderate overclocking, maybe that leads to a better Q60 >> solution one day. > > Very interesting, since the best solution would indeed be to gain a > standard resolution output on the Q60. My personal preference would be a solution that includes more VRAM, so it is not interpolated, but an actually usable resolution. Besides lack of time and the BGA soldering issue, I remain unsure if such a massive board modification is appropriate for a historic computer. A lot depends on the question, what do we actually prefer today: Keeping the historic machine alive, or any 68060 machine that has decent video and runs SMSQ/E? >> At the moment I still struggle with manual BGA soldering. > > I never tried that myself...
