Maybe because on the older machines (e.g. PDP-1) they really were toggle
I can tell you what they were called internally at DEC.
Mainly due to the fact I was there at the time.
They were called Toggles or Toggle switches and their use was called
'Toggling' hence 'To toggle in the bootstrap'
Any DEC field engineer of that time knew by heart the sequence of octal
numbe

PS: If a way is developed to make the plastic levers, the 11/20 uses the
exact same part, just in PDP-11 colours.
They've been 3D printed with the sintered nylon process, dyed and polished
with good results thanks to the efforts of Vince Slyngstad.

I hear them referred to as handles.

We probably ought to standardize our terminology to be slightly less
confusing. As we've
Thats OK
Its always worth asking.
One of the reasons for my efforts to make PDP parts is to produce spares
using modern
components to help replica builders and restorers.
In addition to the toggle switches I am trying to see if its possible to
reproduce the bezel

I believe many would appreciate that. I'm lucky though and have spares
enough for my machine.

Hello Pontus.
Thank you for the information.
Your two machines (colour sat apart) do fall into my A and B Types quite
well

I dont know if I have asked yo
Hi Rod
I'm sorry I haven't replied sooner, you are not forgotten. It is just
that my second 8/e was much harder to reach than I had hoped for. (I'm
shipping out a set of computers that are in the way).
DOH! I just recalled.. I have pictures online, these are my machines:

Hi Pontus
Please define which two the colours differ between.
Is the current version with the vertical switch position correct?
If that is the case then the other one with angled switch position
lines and dividers between groups of lamps must differ.
The two colours
The color is quite different between the two. I can take comparative
photos, but I suppose it will be quite meaningless as a guide.

Asof now I know of two variations
1,Selector switch positions 1 and 6 lines can be vertical or
at an angle to the vertical
2,Vertical divider between groups of three lamps
Anybody seen an 8/e panel with anything else?
