Subject: Re: [GreenKeys] Need a UGC-136 teleprinter (or 46) ?That's only $52 each. Those look like they really cost a lot to build.
I note in the photo at
https://www.navy-radio.com/tty/ugc136/ugc136-1711-36.JPG that there
appears to be Rogers bus bars between the rows of chips. I used those in
products I designed in the 1980s. I had custom 3 layer bus bars made by
Rogers Corporation. The middle layer was ground, one outer layer was +5V,
and the other outer layer was -12 V. These carried power to the MOS chips
in the product. The Rogers bus bars made it possible to use just two
layers on the PCB since power was distributed by the bus bars. Further,
the capacity between the layers served as power supply bypass capacitors,
so no bypass capacitors were required at the chips.
I hope someone buys these instead of their being scrapped. I don't have
room for any more equipment (according to my wife).
