Many sources like Wikipedia and others claim the first cable modem was in the mid 1990’s, however we know that NABU Network in the 1980s was doing amazing things with cable modems.

NABU Support for Atari Paddles by brijohn:

- Modify Atari paddle controllers to work with the NABU – PDF (114.01 KB)
NABU Keyboard ROM With Updated Paddle Support:
Paddle support already exists in the stock NABU keyboard ROM, however this fixes a bug that causes issues when using the second paddle on each controller port. It’s possible to get the second paddle into a state where moving the controller port’s first paddle causes the second paddle to move as well basically tracking the position of the first paddle. Thanks to NABU MAME developer brijohn for this updated ROM.
