So I've been testing.
Either Tos 1.04 or 2.06 do get the PAK68/2 started.
But is made no difference if JP2 is on or off. It should I guess.
And it's always the German Tos, not the UK one in the MB.
Removing JP4 does make the board see the FPU.
And I tested with 16, 40 and 56 Mhz. There's a difference between 16 and 40. But hardly any more when I go to 56, just a little more heat.
Moving all JP8 to JP11 to position 1/2 makes nu visable difference, but the board keeps working.
I've tested with Gembench 4.03 and 6. Also tries syscheck. All work fine and there's been no stange behaviour.
All in all, both PAK68/2 do work fine.
So Joska, I guess there's just one question left, are you sure the wire patches are in the right place?
That's the last thing I can think of to look for.
Else, just send the board to Frank, he may be able to sort it out.
