PDP-8/e Panel Variants I now have a list of _possible_ (not actual) variations. Its not quite the same as what I had before. In addition I have heard there may be colour variations in some cases. 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 As these only involve artwork and silk screen frame changes I can use the same plexiglas blanks for them Whats the next most popular PDP-8 after the /e? Any ideas ? Rod
