RE: HP 41C Video interface test. Howto?
Let's clear out the hardware requirements first, there were two versions of the original video interface:
  • HP 82163A for North America (60Hz, 525 lines, 75 ohms) [NTSC]
  • HP 82163B for Europe (50Hz, 625 lines, 75 ohms) [PAL]
The interface has two outputs:
  • Monitor => for monitor who has composite input
  • TV => to be used with the TV antenna adapter
To connect the interface to your composite monitor, you must:
  • have a video interface and a composite monitor with the same specs
  • connect the cable between the video interface monitor output and the composite monitor input
  • activate the desired input on your composite monitor, if needed
To connect the interface to your TV, you must:
  • have a video interface and a TV set with the same specs
  • connect the cable between the video interface TV output and the TV antenna adapter
  • then connect the TV antenna adapter to the antenna input of the TV [NA: VHF antenna / Europe: I do not know]
  • select TV option on TV antenna adapter
  • activate antenna input on your TV
  • select appropriate channel on your TV [NA: channel 3 / Europe: I do not know]
