When I get back from Afghanistan, I have plans to buy and review a 27" Tri-mode Makvision monitor and install a 6-in-1 switcher in all the MK cabinets. All the cabinets will have all the different revisions of the original hardware installed in them. "The ULTIMATE REAL MK Arcade Kollection!"
MK1 - 5.0 T-Unit, 4.0 Y-Unit, Turbo Ninja, 3.1 Turbo, Nifty Kombo, and 8.0 Proto.
MK2 - 1.1, 2.1, 3.1, 9.1, Challenger.
MK3 - 1.0, 2.1, War Gods, Wrestlemania, Open Ice, Rampage World Tour
UMK3 - It's Mame so I will put the Mame versions of the remaining Wolf unit boards I have (NBA Jam Hangtime, NBA Jam Maximum Hangtime, etc.) along with rev 1.1, 1.2, and Jugg versions of UMK3)
MK4 - 2.0, 3.0
After all that, I will still have boards left over. Stay tuned!!!
