@BobAlbright
here you can find the manual, press 7 on the keyboard to enter game setup, let me know if you will be able to change the current setting (credits, hi-score, bonus ball etc.), I am really interested:
cycle 7 until match reads 17
drop coins to make credits read 00
5 ball game, normal difficulty
drop coins to make credits read 01
3 balls double score bonus, easy game
drop coins to make credits read 02
3 balls, triple score bonus, easy game
press 7 to cycle to match 18
drop coins
00 hit special for super bonus
01 hit special for replay
02 hit special for bonus ball
03 hit special for 50k points
press 7 to cycle to match 21
drop coins
00 for normal high score counting
01 random score from 600k to 1.7m supposed to make low score happen more frequent (600k is low?)
02 random score same scores but makes medium scores more frequent to appear
03 random same as above but makes them more prone to be top scores
press 7 cycle to 22
drop a coin to clear high scores
press 7, cycle to 23 24 and 25 respectively
drop coins to set the 1st 2nd and 3rd top scores
each coin racks up the score
press 7 to cycle to 26
drop a coin to clear book keeping
hit 7 again and the settings are saved and table ready to play
If you want those random crazy scores, it bears mentioning to read this section 1st

Test 6 sets the balls per game, with none of the bonus multiplier changes
just drop coins until it gives the amount of balls you want
i set it for 5 balls, and 5 ball normal game, no crazy bonuses, and i still cant reach the crazy high scores
