I'm not sure who will be teased by this ancient system
The "Gateway" is actually the entire PCB in the center of the first photo with eight digital and eight analog inputs. It included a "Basic-on-Chip" ROM. The programming language wasn't really Basic, but more like a faux Basic that was limited to
If...then statements. To the right in that photo is a home-built board to process several analog inputs. I had to wire-wrap the board (see photo below).
The other photos show a hand-built humidity/temperature "Link" (shield in Arduino). It used a PIC microcontroller to interface between the sensors and the RS485 bus. The other photo shows another PCB Link with LCD display and plenty of room for add-ons. It was powered by the "Answer Man". "
A low-cost stand-alone or network-based data-acquisition and control module...with speeds as high as 57.6 kbps" Amazingly,
sombody still seems to sell it.
