HP82144A DC charger for Spice (34C)
Newbie here. Hi all!

I purchased a 34C and it came with an 82144A charger.
This charger is marked as "use 10-16V DC only" and has a figure 8 (IEC C7/C8) style connector as input but I don't have a suitable input cable.
The input connector looks to be polarized with a flat top and triangular shaped ridge at the bottom, so not exactly the same as a C7/C8.
I disassembled it and it looks to have a 4.7 ohm 3W line input resistor on one of the inputs feeding a bridge rectifier formed by 4 x 1N4002 diodes so it looks like it can handle, AC and DC and reverse polarity.
Anyone else have one of these and can confirm how to connect it to a suitable voltage source?
I have pics of the inside if anyone with better circuit knowledge than I have is interested in studying it.
