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.
Regards
Rod
