Twisted Pair ----
1A2 old? I'm pulling out a 584 panel with ten button sets this weekend. In a floral shop. Want a picture? I'll take a poloriod and pdf it to you, if you want.
1A1 used co power to pull relays to operate hold, etc. 1A2 had power supplies to do it and have lights. Never played with a 464 but have installed literally truck loads of 564 before TT came to town. Then I put in many 2564s. The shoebox you hear about is normally considered an WECO 551 series or an ITT 601. They are both the size of a shoe box, therefore the name. Normally 4 COs and a chance at a ICM.
Let me know if you want that pic.
