The first one that comes to mind Mel is that the Hydraulic panel is completely different on the 767, it has primary and demand pumps with a rotary switch for the demand pumps with 'OFF', 'AUTO' and 'ON' positions.
The pneumatic/air conditioning panel is also different on the 767, it has left and right isolation valve switches. It also has 4 zone temp selectors (3 cabin and 1 flightdeck), on the -300 anyway, I can't remember the -200.
The 767 has cargo heat push button switches on the overhead for the 'FWD', 'AFT' and 'BULK'.
The equipment cooling selector is a 3 position rotary switch on the 767 as opposed to a push button switch.
There is also the fuel jettison system on the 767 aswell, and these are only overhead panel differences, I am sure I could come up with more if I thought about the whole flightdeck.

Yes the P61 panel is present on the 767 aswell. The layout of the equipment on the P61 panel is usually down to the customer spec at build.
On the 757 you have hydraulic isolation switches for the 3 systems going to the tail but on the 767 you can isolate the wings aswell. There are 6 switches one for each system for the tail and one for each system going to the wings.
The squib test lights are different, there is two test switches and only the test switch one will light up the APU light because there is only one squib for the APU.
There are a few other slight differences aswell that I can't remember right now.
I have seen the EICAS screens there on El Al, but never a real F/E panel.
Who has this? Are they still working, or have they all been converted to 2 crew operation now?
Your top photo looks like a standard B767. Very similar to a B757. No switches there to operate in flt.
Yes now I remember.
When the B767 was designed it was a 3 crew aircraft. Before delivery it was changed to a two crew aircraft, but the Ansett unions managed to insist on a 3 crew aircraft.
While short range aircraft had been two crew for ages, it was the B767 and A310 which introduced long haul two crew aircraft, and it was very contoversial at the time.

And don't forget the step into the cockpit!
Up into a B767 and down into a B757.
Why is this Difference present.Any reason.Is the Main Deck Floor Height Different.
My interpretation is that the upper lobe of the 767 is much larger, so there is more space for the flight deck. The 757 has a narrower body, so the flight deck has to be pushed down towards the centre of the fuse to avoid making it stick out..

Let's not forget the F/E position in the 767 cockpit.
An EICAS screen on P61.Thats new.
As I recall, that whole F/E position was a huge hash-up.
