Yes most helpful Vince.
The multitude of variants did rarther surprise me.
As you say the switch change does have to be catered for. (its now a C
or a D)
I have had one very good scan of a B panel in from a prospective client
with yet another variation.
The title header for the EMA is in its own box and not attached to the
first memoy address header
I now have a list of possible variations.
Its not quite the same as what I had before.
A is the current shipping version
A No dividing lines between lamp groups
Position 1 and 6 on select switch vertical
B Dividing lines between lamp groups
Position 1 and 6 on select switch vertical
C No dividing lines between lamp groups
Position 1 and 6 on select switch angled
D Dividing lines between lamp groups
Position 1 and 6 on select switch angled
What I need to do is work up a portfolio of photos with an original on
one side an my replica on the other.
What is annoying is if I had travelled back to 1978 I could have walked
into the production control office in Parker St and
pulled out the file that would have told me the whole 8/e panel history.

Rod

The current debate has produced a growing list of
differences between the front panels of just one model
viz and towit the PDP-8/e
Here's my list so far
...
It would be nice to be able to correlate the one list with the other
Suggestions plese gentlemen
I would suggest that cataloging the history of 8/E front panels is an
interesting project that I wish you luck with, but it needn't impact
your production.
It seems to me that if attractive and mostly historically accurate
panels of types "A" and "B" (to fit the different rotary switches)
are available, the other differences are akin to the font differences
and replica markings you have already talked about.
Certainly the result will be clearly an 8/E (or F or M), and without
whatever damage (or loss) caused the original front panel to be replaced.
