I have
* Area 51 / Max Force upgrade security chip - 20.00 (reduced price) dual layer board
**NFL Blitz2kGold ( Seattle Boardset) - 25.00 (includes boot eprom)
**NFL Blitz2kGold / NBA Showtime Showcase (Vegas Boardset) - 30.00 (Included boot eprom v3.0)
These are shipped prices.
I can also offer 'kits" (ie security chip,needed eprom(s),harddrive) message me for prices.
If you are curious as to what these are even for:
These security chips are needed to make certain games work, atari and midway (and others) used the same board to play several different games. However; they used these security chips to keep people from just upgrading the game on the board to the newest edition. So for instance, if you have a plain vegas NBA on NBC game, you can get this chip and make it both NFL and NBA on the same board. Also if you have a dual layer plain area 51 game, you can make it both area 51 and maximum force on the same boardset giving you two games in your machine.
* You will need to change the 4 eproms and the harddrive, this kit sells for 100.00 on ebay I will only charge 65.00 or (35.00 for just eproms, you buy yourself a harddrive).
**If you buy one of these you will still need to change the harddrive or buy a new harddrive. They are cheap on ebay or you can make you own for less.
