Hi all,

 

I am doing more in the shack these days and putting more time into my teletype set up. I have an M28KSR and M28ASR and one desktop printing reperf (LPR ?). I find it would be convenient to be able to put the LPR into mark-hold mode while the other machines type away. But to do that, I would need a separate loop supply and switch the LPR between the main loop and a mark-hold loop. My ASR has something like this. The internal LPR can be driven either by the keyboard or the loop. I have a switch under the TD that allows me to turn the internal LPR on or off. When turned off, it doesn’t run open because there is a loop supply. The ASR has a LESU of some kind in the cabinet that makes this all happen, IIRC.

 

The question is, am I the only one who thinks a local loop for the desktop LPR would be a useful thing? Did they ever make such a beast? And finally, I assume since it is just mark hold, I could cobble up something simple to provide 60mA where the voltage would not be that critical?

 

Any thoughts or suggestions?
