If you ever talk to the guy again, would you mind asking him if he ever had the Docking Card for the 125? The Docking Card installed inside a Mac Plus or SE, and allowed you to connect the 125 to the Plus or SE by a cable and then you could use all the ports and drives on the Plus or SE and the second display, as well as the components on the 125.
The Outbound uses a 19VAC, 1.mumble (really close to 2) amp adapter. The rectifier to DC is built into the base of the 125. It's in that little metal can in the base. I have the specs for the plug somewhere. Radio Shack used to sell a compatible plug in their universal plug kit.
The 15 connector on the side of the 125 is *not* a VGA port. Do not plug in a monitor. You will blow the power supply.

Do you have the internal floppy drive or the internal hard drive? The 125 came with one or the other. If you have the internal hard drive, it can be inconvenient if you don't have an external floppy drive for it. That's an Outbound external floppy. There's no way to connect an Apple external floppy. On the bright side, the 125 uses a 1.44MB/800K/400K floppy even if the ROMs are from a Plus.
To turn the Outbound on, you hold down all four keys in the little picture on the keyboard simultaneously. Also, there is a battery compartment in the keyboard. The machine won't start if the keyboard has a flat battery. The battery is some kind of oddball lithium thing, but you can substitute two 'N' size batteries. They fit and the voltage is right. From the photo you provided, it looks like the battery compartment cover for the keyboard battery may be missing.
The main battery in the 125 is still available. It was a standard and common Panasonic camcorder battery. It's lead/acid and I think they're about $30 these days. Do not drain it all the way. Lead/acid does not recover from complete discharge very well. This is the opposite of NiCd which liked to go all the way down to zero.
Next to the main battery compartment, under a little metal plate is a 6V camera battery. This will preserve the Silicon Disk contents while you change the main battery. However, if you let the main battery go flat, this little camera battery will also go flat within a smallish number of hours, and it's a $6 - $8 disposable. So, either don't install it, or don't let the machine sit with a flat battery.
The silicon disk is a RAM disk composed of whatever memory you install in four SIMM sockets in the machine which are dedicated to that purpose. It can go up to at least 16MB of silicon disk. Back in the day, a 16MB hard drive was pretty respectable all by itself, and as long as the battery isn't flat, the disk is persistent. Shut the machine down, the silicon disk keeps its contents. I use the silicon disk as the main boot volume and the hard drive is really just there as back up and off-line storage.
On the back of the keyboard, you'll find a port for a mouse. That's for an old Microsoft Bus Mouse. Not PS2. Not serial. Not ADB. The pointing device is great, so you don't really need a mouse, but to prevent you plugging in other odd ball stuff. There is also a telephone cable type connector, which allows you to operate the keyboard in detached/cabled mode. Otherwise it communicates by IR, either with the keyboard at a distance or latched to the base unit.
