I've had a 1A2 system at home for many years. It's been modified with a circuit replacing the 400E card so non-A lead phones can be used and provide off hook status. Hold is kind of reversed, line 5 is converted to a momentary pushbutton and a couple of leads are moved. It has a Melco intercom, pressing 9 gets the CO line. Previous circuits had a line isolation transformer and used A battery, but I no longer use the original Elgin power supply. It's quite basic - pressing 9 sends a momentary +24 to the circuit. I'm going to attempt to insert a link to the schematic, sorry if it doesn't work. I'm not sure if I should chose "Insert an image' or 'Create a link to a webpage' - - The 'Dial 9 acess' link appears to work. Dial 9 access
