Thank you Nick, for answering those questions before I even saw them, for filling in a couple details I forgot and for providing the link to the manual.

If one uses an the external power supply to power all six loops, remember that is 60 mils times six or 360 mils. 360 mils is the max output on my supply. I did not want to push it to its limit. I only use it to run three loops, so it loafs along at 180 mils.

One more comment - I think Goff's price is very reasonable considering how useful these units can be. I was lucky, I got my 1210 for free, but I would not hesitate to pay his price for a 1203 if I needed one.

Study the wiring of the "set jacks". When you patch into one to get access to a teletype, the Teletype is disconnected completely from its loop and the loop is bypassed by contacts on the jack. Then you are free to patch that machine to any other loop. As I said - it is amazing!

By the way the 1203 has six "set jacks" the 1210 has twelve "set jacks" of which I am only using only five - four model 28 printers and a dome reperf. Unused "set jacks" must be bypassed on their terminal strips to complete those loops. My first four loops are connected to an SB6-GG which is a similar, but non-powered, patch panel for four loops. I have that in the basement where I have my three 15's. It is a very useful accessory to the 1203/1210.
