Polite MOD notice, can we please stop pestering in design threads, there is a specific For Sale forum for sale threads!

Is this a design thread? From first message of thread starter:

I am wondering if there is a demand for more Q60 boards, which D&D System used to sell.
...
I will look into production of Q60 later this year as I have some Q68 to build.

What are you a tabloid with selective editing, he then immediately after that starts to discuss the merits of different hardware configurations!

The key point was the last statement, in my initial message:

Except, I would only want to produce a Q60 with 80Mhz 680LC60 with MMU, but without a FPU.
There is a problem with the VGA output when in 1024x512 Mode 33 not working correctly on modern TFT monitors.
I used to use a 17" CRT SVGA monitor, but these monitors are very expensive or not available.
The OSSC video converter could be used to convert the video signal on the Q60. But the OSSC is very expensive, but is open source, maybe the hardware could be customised for the Q60.
Just thoughts here...
I will look into production of Q60 later this year as I have some Q68 to build.
I do not want the problems with everyone with strong opinions making the job harder than it is, back in 2002, I had all sorts of opinions to content with that would of easily stopped the project.
I realised, I may of opened up a "can of worms", in that, everyone wants a Q60, when the parts maybe not available, there is no pricing structure, can the board be mass produced, or has to be made by hand. All these questions have not been address yet.

The original machine is purely made from throughhole type components. It will still be possible to have them machine soldered, but that has become very expensive. Various components are obsolete, but available. The CPU socket is not available, and needs to be "tinkered" - or the CPU soldered directly.

Hi Peter,
I am in the process of looking into the problem of part availability, which why I do not want get everyone expecting anything.
I would just hand solder the Q60 board, as was done in 2002.
I soldered the first 2 board and 50% of the rest, my D&D Systems colleague, then did the bulk of the soldering work.
Leaving me to handle, testing completed boards, build cased Q60, produce a manual, applications software support, give technical support and do any repairs.
Maybe it not that much work...

It is a massive amount of work. Personally, I wouldn't do it anymore as I got older.
If you actually handsolder those mainboards, people should highly appreciate it as an extraordinary service.

You maybe correct, but my fatal flaw, is that I did not keep a Q60 for myself, so I am back to having to build one for myself.
But the project is looking a little harder, as the parts are available, but alot more expensive.
Also there is the problem of forged CPU, which is why I have an Amiga A1200 with 68060 board, so that I can identify the CPU, because the Amiga people have software that can identify the internals of the CPU. Once completed, the Amiga will be sold, I doubt there will be any money lost.
I am part way through the Q60 parts list, so still accessing the situation.
May have to take a break from this, as I have some Q68 boards to build and sell.

The good thing probably is that SMSQ/E will work fine with any 68060 version (that is, full, EC, LC) provided it works at all

I may be able to help here. I have a CNC and have made some custom PGA sockets that are unobtainium for friends. It went so well I am collecting every PGA pattern so I can take a request and just hit "go".... I sourced the correct 2.54mm black high temp Nylon 6. It would be a shame to have to solder a CPU that hasn't already got solder on its legs. I'll look up the pin pattern and spin some up.
