Would it be too much to design a revised and modernized QX0 PCB with these features? The PCB could come with sockets but no ICs and people could simply transfer their current ICs across to the new board? You could use it as an opportunity to update the video, power and memory sections... I think a lot of people would be interested in that. It would also keep costs low for Derek, as he wouldn't have to gauge demand or buy expensive components like bulk 68060RC75s
The problem here is there is a lot of "Fake" 68060 CPUs, with reference to the amigiwki.de:http://www.amigawiki.de/doku.php?id=de:parts:68060_mask
Details the 68060 Masks and CPU time line.

- The probably hardest to source components, the 8 VRAMs, are not socketed. CPU sockets are a pain to get.
- Once you start an improved PCB, you automatically get from idea to idea what could be changed, and have a completely new design in the end
- The Q60 is a retro computer by now, the PCB already designed in 1997, and maybe it should be preserved
Removal of the soldered VRAMs can only be done with specialist desoldering equipment. I have done this by hand, but there is a risk of damaging the internal layers of the PCB.
Though the Q60 could be classed as Retro, I am still getting enquiries for new Q60 boards.
I can source all the current parts for the Q60, the CPU maybe a little challenging.

THis could be an option for future development, the Vampire 2 would be ideal, but I quess the FPGA source code would be closed source. So development from the beginning would be necessary.
Also who would perform the development of the software to run on the daughter board?
