Front Panel Tech Note 2

[Pontus Pihlgren]

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:

Type A:

Type B:
http://www.pdp8.se/slask/front_paneler/pdp8e_typeb.jpg

As you see, the Type A, which I believe is older, has straight switch 
position lines, no dividers and a "box" arround the switch.

The Type B has angled switch position lines, dividers, but no box 
arround the switch.

Type B has noticably less saturated colors.

I can take better pictures of the Type B panel which is accessible, but 
I'm not sure it will help.

Regards,
Ppntus
