My 1st IGT Slot Machine and what I have done so far

Good to hear! I don't know a lot about BV but I'm sure everyone else here does. It's fun an exciting to do what your are doing just keep going. You will get it!!

Did the clear/key. Still have Display's Netplex Link Is Down. And no sound or hopper anything. BV still works. Also noticed the coin comparator is working great! Was having trouble, I thought, with quite a few coins just dropping through. Was going to get to it and check/clean the optics. But now I can rapid fire insert them and 99.8% go in no problem. I am going to go out on a limb here and suggest that when the BV was not working, it was taking up a whole lot of processing time. Maybe trying to communicate all the time. I also set the game this time to max, 5. Maybe that's it but I don't know. I don't have the Simplex Netplex error either, maybe that helped with the coin comparator thing too. I may have set something up in the menu for that or progressive by mistake on the last clear/key. Probably won't know. Will check P/S voltages tonight.

Many thanks to Jim @ Midwest Slots! I got the new parts today and after a bit of setup my machine WORKS! Hopper is still not working. I can fix that. The machine sounds great. Looks like everything else is going to be working. I'll check it by playing for a bit. So, replaced the MPU PCB with 504, Sound board and Simm, got the 363 chips installed and all good. I will repair the original MPU PCB later, I have a working one to compare with now. Now I will concentrate on hopper and getting my modification project completed. Thanks again Jim! Thanks to all others who helped with the suggestions and information. Sometimes the boards are just bad.

Finally got the Hopper working. That should complete this post. I believe everything on the machine is working correctly. I will repair the original MPU PCB when time and need permits.

Hopper was basically stuck.  Maybe just sitting for long, maybe just full of lint/debris. I am going to purchase a new motor and see if it runs a bit faster.

The crazy thing, I got it working on the bench with a 12 VDC power supply. Looked good for 12 VDC. I could spin it very easy with the gear on back of motor. Every time I put it in the machine, nothing, not even a little bit. I put it in the menu hopper test and banged on it, and finally after turning the gear on the back of the motor while in test, it drove a little bit.  I was elated. Took it apart a bit and removed the lint/debris I could see, spun it by hand a bunch and it seems to work all the time now. Maybe needs a new motor, maybe some lube. I'll give it a try.

Thanks again for every ones help. Could not have done it without the help and information form everyone and the forum posts.

PS.  I am going to get going on the modding of putting my electronics in the machine so I can control every thing any way I want. I'll post when I have something to show.

I don't know if this was a problem but the hopper motor gearbox has grease inside it and sometimes that grease begins to dry out, gets thick and harder for the motor to turn the gears. When this happens there are different techniques to fix things, such as drilling a small hole in the top of the gearbox and adding some fresh gear lube, then covering the hole you drilled. Or you can manually work the motor until things start turning, then run it for a while to get the gearbox warmed up and stir up all that old grease. The machine Test menus have a hopper test that will turn it on and run it while dispensing 10 coins.

Glad you got the machine working completely.
