Game Traits:
(Submit your own custom Fields)
Has Faceted Inserts - Most games had special faceted inserts. According to Steve Richie the game designer... "Black Knight was the first game ever to employ faceted inserts (the transparent inlaid plastic windows) in the playfield. My design was a simple eight-sided "Jewel Look", but insert texturing progressed from there to many different designs, finally settling on refracting radial lines originating at the center of round and rectangular inserts and from points of arrows and lightning bolts, etc." Reproduction playfields do not have faceted inserts as described but instead have the more common 'starburst' inserts which have radially emanating lines. | |
|
System 7 Power Supply. - Black Knight used two diferent power supplies, the System 6 version with the transformer in the head, and the system 7 version with the transformer in the cabinet. | |
|
CPU DIP SWITCHES - Some early Sys 7 games had CPU/MPU boards with 2 x DIP switches, 2 x Diagnostic switches and 2 x LEDs extra to the 7 segment displays. I'm interested if this was the early BK games with Transformer in the backbox. | |
|
SBA Coin Mech - Some have the Susan B. Anthony Coin Mech installed in the center coin location with the yellow "Dollars" insert. | |
|
Multiball lamp insert - The majority of games used red arrowhead inserts for multiball lamp. However, some very early machines apparently used green inserts here. | |
|
Multiball Plastic Protector - Some games had a steel plate installed under the plastic that covers the multiball trough in order to protect that plastic from breaking. | |
|
Ball trough microswitches - Due to quality control issues with incorrectly manufactured leaf switches, Williams produced a retrofit set that converted the lower ball trough and multiball lock trough to use microswitches instead of leaf switches. | |
|
Drop Bank Rebound Switches - The original playfield design had a switch behind three of the four banks of drop targets (there was no room for this in the upper left drop bank). When the targets were down, the ball would hit the rebound rubber behind the targets and thus hit this switch. The switch was removed because it was not hit much. The timers would reset the drop target banks, so these switches weren't exposed often enough to justify the cost of keeping them. Three images are presented here of the center drop target bank, as an example. The left image is the flyer game, and a blue circle has been drawn around this switch. When games did not have this switch, the playfield might still have the cut out for it (center image). Your game may not even have the cut out (right image). | |
|
|
Cabinet Bottom Material - Games seemed to have been manufactured with different materials on the bottom of the cabinet. This may have been due to Williams using two different cabinet companies because Black Knight was such a hot seller. | |
