Beckman SP-450 Alphanumeric Variant Panaplex Display  
Written by AnubisTTP on 2018-01-24  


Beckman produced a number of late-era, flat packed panaplex displays with the SP-450 part number, all of which have a similar construction style but differ dramatically in layout. This SP-450 variant is particularly large, and is equipped with 32 alphanumeric characters arranged in two rows. A small evacuation nipple is present on the back of the the display from the pumpdown and neon-filling process, but all other connections exit the sides of the display along the sealing seam. These connections are a combination of printed conductive traces and spring loaded leads, the latter of which are fused to the display with a bead of solidified frit. This display is so large that the manufacturer had to include four internal glass pillars between the two rows of characters for added structural support.
