I believe the top photo is of the Manitoba Lotteries Commission (MLC) Game Set.

I've got that software, but the games lock up anytime there's a Bonus Round. I'm assuming that it's looking for a server or something to validate the game once it goes into a Bonus. Just a guess though.

It's a decent set and can be played on a BB2 as long as you don't trigger a bonus. Lol.

Pictures are helpful, although small but your last photo was very revealing.
First of all, it shows that the machine was made in 1997.
That photo also shows the top of three chips that contain 27 year old Lithium batteries.

Now would be a good time to pull one off, noting it's orientation for re-installation later, and to see how much battery corrosion lay beneath the black plastic cover.
See if you can get a voltage reading of any kind, with a voltmeter.
I cannot imagine how hard it is to find  replacements, should they be dead.
Which brings to mind the question of whether or not you have ever seen this machine working? 
Zero history of this machine has been forwarded.

For sale:  (2x) GameKing 19" I/O Board sets. These are for the older 1st generation GameKing machines with the large pullout I/O tray.

$50 per set plus shipping.  See pictures.

Thanks for your reply qbert. Slowly I'm getting to know this game. I posted an error that pops up all the time when turning on the machine. If I restart a couple of times like the screen says it will eventually start and I can play some games. Doe's anybody think that is a board or OS card problem. Thanks so much. Bill
