Both to the touch screen monitor. If you look a the photo of the back of the panel (5th photo), the grey lead (far right) is one of them and the black (far left) is the other. Neither drop into the bottom box.
Can't see anything like a dongle. 2 Usb slots are empty, 2 have leads but I've traced those back and they both lead to the touch screen panel. I've attached photos of the machine to show. (most of those photos have uploaded the wrong way around so you'll have to look sideways lol)
I assume the licence is just installed for the 4 playable games. I don't know of any fruit machine companies so I'll have to do a bit of research. I thought they'd be like any pc, where you can get cracked games for them or download a licence or something to a USB stick.
Thanks for the info! I wish there was a way to put it into demo mode and play all the other games like that.
Any ideas of where to get one? Or can the games be downloaded and transferred to a USB stick from somewhere? Obviously we can't pay £900 for 1 game from Astra lol its only for home use.
