tp, back in the day every H & R Block tax office around here had one of these. Some called it a "Shoe Box".

So that's the shoe box 1A2 system!

Going by memory --- Boy, that's a mistake :scratch: --- the A and B were metal, the C was plastic covers. The ITT had a 601 --- very similar. The 601 did look like a shoe box ! :rolleyes:

Yep Ken, your memory is working today. 551A was metal and had a twist lock connector the bottom for the power cord. 551B was also metal but just had a plastic grommet installed in that hole. An extension cord just passed through it to the power supply. 551C was the new all-plastic version with a dark gray lift-off cover. The ITT 601 sure packed a lot of stuff into a little box, I mean it even had a slot for a 10 station intercom card!

It's amazing to me that after all the years of people dumping old key systems, some of us are reintalling them! There's still some of the old boxes lurking in communications closets. The few times I have been asked to clean them out, I have come home with neat old stuff, and a little newer stuff too! The 620A panels and key phones I use at home have proved reliable. And combining it with VOIP and Asterisk has turned Bell history into high tech. Another benefit has been the practice of wiring, punching down and setting up the backboard. This has come in handy when I wired the office.

The more neat old stuff I can find, the more I can put into the collection. There's so much new technology to learn but the old ways still can teach new things.

rotary500, shh, not too loud, Bob3470 thinks this stuff is only good for grow opps!

:rofl:

Will 10v lamp battery power all of your grow lamps, too?
