In looking through the OptoMux User Manuals for the B1 Digital Brain (3rd Ed, 1984) and the B2 Analog Brain (3rd Ed, 1984), I saw under the IDENTIFY OPTOMUX TYPE command (F) that I can expect one of three 2 digit codes on a successful reply:
00 - Digital OptoMux
01 - Analog OptoMux
08 - OptoClock (real time clock)
I understand the hardware referred to in this post is old and obsolete, but they are still rocking and rolling for me. In writing an application for a friend that controls a model train layout, I saw the above and my curiosity was spiked.
So, can anyone describe the OptoClock from a hardware perspective?
How did it integrate and support the OptoMux hardware?
Did the OptoMux protocol support it?
