game is semi working but still some bugs. Here is his latest email::
Hi Warren,
I worked the whole day on the Orbitor. You will be pleased to know that I traced the coin mech wiring, and found the red-yel wire severed in the machine. After looking at the schematic, and making sure that I was connectinf the right wires... the machine NOW will give credits through the coin mech
That was kinda huge, because now I could actually play. Things were still wrong (the sound) but I could pay the game YAY !!!!
After 20 or so games, I felt like I could go on shooting the problems, especially since the sound was so horrible. I pulled the speaker and found the second pinball stuck to the magnet (the first one fell out of the machine while we were moving it into the house, and it fell below the deck

I was wondering what had hapened to the other one. Mystery solved.
The speaker tested fine. The game also has no speech, which is a big bumer

. After examining the sound board, and seeing nothing visualy wrong, I decided to power up the machine with the VSU disconnected. Now the sound is perfect, NO buzz on powerup, and crystal clear. I re-conected the VSU, and BUZZ CITY and makes the sound really BAD. So I don't know whether it is the VSU or the MPU that has a problem, but something is definetly not right there. I am guessing they aren't easy to come by.
I checked all of the lights that are out, and there is no electric pulse getting to them. There are like 20 lights out most noteworthy are most of the ORBITOR lights. I didi get 1 or two to work, that were simply bad contact.
There is one other unusual intermittent issue, when the game starts, and a ball is moved to the shooter lane there is a sound (like the ball hitting the lower spinner motor), you get 1000 pts and the flashing lane light goes out, and the timer begins. The same thing can be reproduced by hitting one or both flippers. I would really like to get that solved.
So we are in MUCH better shape today Warren. Got just those problems I just mentioned left woo hoo PROGRESS.
1 - ~ 20 lights still out, all connections seem good - I have not done any deep diag on the lamp driver board (bleh)
2 - There is no digital voice (bleh)
3 - The phantom switch closure when coils fire on new ball or flips (not sure wht this is)
