• Beckman Instruments Model 827-V6 Mi-Crobar
  A hybrid microcircuit from Beckman Instruments, ca. 1970

An IC and component tester from 1986

• Beckman Industrial Scopemate 2 Schematic

A 40-character vacuum fluorescent (VF) display from 1984

• Beckman Industrial VF-0140-C1 - 1 CPU
  
• Beckman Industrial VF-0140-C1 - 2 Decoding Logic
  
• Beckman Industrial VF-0140-C1 - 3 Display
  
• Beckman Industrial VF-0140-C1 - 4 Notes
  
• Beckman Industrial VF-0140-C1 - 5 Power Supply
  
• Beckman Industrial VF-0140-C1 - 6 Microcode ihex
  Here's the EPROM image, courtesy of Michael Lyon
  
• Beckman Industrial VF-0140-C1 - 7 Microcode asm
  This was obtained from the above ihex file using using Jeffrey Post's D48 dissassembler
  
• Beckman Industrial VF-0140-C1 - 8 Datasheet
  Sort of. This is actually a Babcock VF-0140-02 datasheet that dates back to 1985. They bought out Beckman's display division, and although this document is not actually for the -C1, it does contain some pertinent information.
  
• Beckman Industrial VF-0140-C1 - 9 BS2 VF Test Circuit
• Beckman Industrial VF-0140-C1 - 10 BS2 VF Test Code

• Motor Controller - 1 Schematic
  A motor controller for fractional horsepower AC permanent split-capacitor (PSC) motors. This one is designed for the youth or student as it sports an instructive, easy to use front panel.
  
• Motor Controller - 2 Application Notes
  
• Motor Controller - 3 Mechanical I
  
• Motor Controller - 4 Mechanical II
  
• Motor Controller - 5 Layout
  
• Motor Controller - 6 Notes

• PWM Motor Controller
  A DC to PWM Motor Controller for HO trains (or many other things)

• QuadSink Motor Controller
  The perfect motor controller for the student or hobbyist
  
• QuadSink - Sheet 2
  
• QuadSink - Sheet 3
