I think you're right that someone made an S-100 board to operate BSR house
controllers.  I don't remember the details, as I was turned off by the
idea of running 110 volts onto a PC board.

There was also an article by Ciarcia in Byte that described a circuit to
throw ultrasonic pulses at the BSR controller box.

But I think the method of choice now (at least I chose it) is the
Heath GD-1530. It takes an EIA serial line (transmit side only) and
reads commands like "A1<return> AON<return>" to turn on module 1 of house A.

This was not initially the method of choice because it was ridiculously
expensive at $250. But it was reduced to $99 a while ago, which makes it
much more reasonable.  I guess 8748s got cheaper.
