It looks like it's exactly that. The zany CHIP computer 'wifi modem' used to connect is itself a more powerful computer than the vintage 'terminal'.

However that can be replaced with a plipbox (I believe he has open sourced it and you can build your own).

30 years after it was discontinued, you need a computer many thousands of times more powerful to connect the //c+ to a network. That computer costs $9.
