Welcome! Looks a lot like my Vendo VF90D, same coin insert. Yours is a little wider, so it probably holds a few more bottles width-wise. Each of my shelves holds 9 bottles.
You can download the manual for the Vendo 63-90-126 off the main page, under downloads. This should help you with the wiring and general vending settings, although a few will be different.
Very cool score for 35 bucks! Mine had dead bumblebees in it, an evacuated hornet's desk, and had been sitting outside for some time when I went to get it- the seller told me it used to work but then just mysteriously stopped, so there it sat for years afterward, unused, outside.
I brought it home, looked over the inside, and couldn't find any damage. I looked at the cord, and there was a section about a foot long with electrical tape wrapped around it... I cut off the e-tape and lo and behold, one of the wires had come apart.. I twisted the broken ends together, plugged it in and............... she lives again.
The best part about it is my wife really wanted the machine, and being able to bring it back to life for her was simply the best. Chances are it won't take much to bring yours back to life too.. Keep us posted!
