The original EADI did not have a speed tape, hence the analogue velocimetre and all other items of the traditional instrument T. The speed tape became an option only later.
I understand that a PFD has all the necessary information in one single display.
Interesting, the „EADI“ on our classic 737 had both an altitude and speed tape. They missed stuff like navigation performance scales and GLS/IAN indications though that were standard equipment on our NGs, same as the vertical situation display on the ND that the classics did not have.

My Company and another large freight operator has re-fitted all our 767 cockpits with new Flat Panel displays, similar to the 767-400

Never seen a 737 classic with an altitude tape, do you happen to have a photo of that?

It's intereting to me how even 757 pilots refer to the EADI/EHSI as PFD/ND. Either they know the correct term is EADI but say PFD instead because they think others won't know what they're talking about, or they don't know it's called an EADI. Never sure which is true.

Perhaps they were talking about these?

I have this interesting 2002 brochure by Boeing on the 767 avionics/flight deck, but could not attach it directly. So I created a Dropbox view/download link instead.
Please note the PDF is almost 16 MB large.

I think many might find it interesting,

On the '73 Classics I flew, PM had to adjust the Flex thrust manually on take-off.

Does anyone have a copy of the Boeing, (or any), 767 cockpit set-up and flight phase flows etc.?

Is there a tiller on both sides or LHS only on the '76?

probably 12-13 years ago,
No doubt the screens were full of information, but it seemed more like over-load:

No idea if that was 764 displays, or some generic in-house retro-job.

Those are not directly related to the 767-400 (which was basically all new avionics with the thrust lever quadrant from the 777). Somebody did an STC to replace the original CRT displays with a couple of large Flat Panel displays (I've forgotten who the vendor was that did it) but the underlying avionics were largely unchanged.
FedEx had placed a huge order for 767 Freighters, but was concerned that over the ~30+ years they planned to operate them, CRTs would become unavailable. So they had someone create a mod to replace the CRTs and the associated interface hardware with flat panel LCD displays. Initially, they'd fly away brand new 767 Freighters, remove the CRT hardware and replace it with flat panels, and ship the CRT hardware back to Everett where it would be installed on another new 767... Realizing how incredibly inefficient this was, Boeing was able to jump through some certification hoops that allowed the STC flat panel displays to be incorporated on the production line - and at some point new production 767 Freighters had the flat panel displays as-built.
That was a real eye opener for those of us responsible for cert - we wondered how we could show compliance for an STC installation done by another company - but it turns out there was an FAA approved process that basically said if the STC had FAA approval, it wasn't our problem. Given how sloppy some of the STCs I was familiar with were done and certified, I was far from comfortable with this (and I was far from alone), but the FAA said it was OK and I wasn't about to contradict the FAA...
