HP 41C Video interface test. Howto?

[Sylvain Cote]

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]
