We had those scientific Altanta boxes. First the original ones were more like down converters. If you put the TV on ch 2,3 or 5, the channel numbers displayed on the box were all off by that many channels from the channel 4 the TV needed to be on. They had a mysterious AU button, which did nothing.
Then they got newer ones with an OSD that showed the channel name and number. Then the 8610X had a very rudimentary guide, and finally they moved to Motorola digital boxes.
Hey why did the manual for tocom box posted say General instrument on the bottom of it?
It’s also funny how they spelled Jerrold back in the day. President Ford must have been giving them a crazy eye. Yeah I know Jerrold became General Instruments, which then became Motorola and today Arris.
For a long time there were still cable amplifiers outside with the “Jerrold” name on it. Over the years some companies just put new electronics inside the housings. I think that only worked to 550 MHz, so then they put in General Instruments or Motorola depending on the timeline of the system upgrade.
