I just acquired a Pinbot and I am in the process of bringing it back to life. Does anyone have (or is willing to make) a drawing of their playfield and the locations and colors of the various LEDs they installed?

Does anyone know a source for Pinbot decals? I need a helmet decal (the large piece at the very top of the playfield, not the visor) and the decals for the blue ramp. I was able to contact Jeff at Classic Arcades and he said maybe, but he has not responded to phone calls, emails or texts for a week since then. I can't seem to find a source in searching the internet.

I need that sticker also. Please PM if you have a file and I'll make a waterslide decal.

I found a place called "Collectible Heaven" that has some listed but they don't have a phone number or a way to email them (that actually works). Does anyone have a phone number or an email address for them?

Here is the link to their site (collectibleheaven.com does not work and emailing to [email protected] fails):

I just got ahold of Jeff at Classic Arcades. I will let you know what I find out about the helmet decal and I am also looking to get the ramp decals.

I sent pictures to Jeff of the decals I needed. I still haven't heard back from him so I'll keep trying!

Cliffy restored a Pinbot and used a decal from Jeff, so there appears to be hope ("Jeff McAfee's great helmet decal" is at the bottom of the page per this link): http://www.passionforpinball.com/pinbot4.htm

I tried twice today. No answer and he hasn't responded to texts or email. Maybe somebody else can get through...........

Does someone have a factory manual from which they'd be willing to scan the schematics from for the sound board? I have the one from IPDB and it's not of very good quality. PM me and I'll send you an e-mail address. Thanks in advance.

Regarding the sound board, I have the voice with my Pinbot but no music. I have swapped in a good MPU from a Jokerz so that does not seem to be the issue. This is my first experience with a Pinbot so I don't even know what the music is supposed to sound like. The sound board has been recapped and I have a new sound ROM for U4 on order. Where do I start trouble-shooting the board? I have a probe and a digital-multimeter.

Thanks.

I checked the voltages and they are all good at J3. There is activity on the board (when using the probe), but I don't have a clue as to what chips to check or what the probe should read.

No scope. Can I check it with a probe?

Grumpy is right! I had a similar problem with a project Pinbot that I purchased and I wish I had read his advice before I started trying to fix it.

I had a short at Q9 (it runs the three 1251s for the right eye on the playfield). I incorrectly assumed a bad transistor since I could find no short in the circuit. I replaced Q9 and Q5, and I turned the machine back on. Q9 quickly smoked and burned, and I was back where I started.

I ran Leon's test chip on the MPU and discovered that the PIA at U10 was bad. I replaced it and the 7408 at U18 since it is in the circuit with Q5 and Q9. I put the MPU back in and wired a 2 amp fuse in the circuit at J12-2 (the wire from Q9 on the MPU to the 1251 bulbs for the right eye). I turned on the game and the fuse blew the first time the 1251 lights were to be turned on. The fuse saved all of my work from melting once again.

I went back to investigating the 1251 circuit and discovered that the previous owner had unknowingly dropped a screw into one of the 1251 sockets and then forced a bulb on top of it. That triggered a dead short only when the transistor at Q9 "closed" and the resulting short probably ruined all of the MPU components in the circuit (Q9, Q5, U18 and U10) before the special solenoid fuse on the power supply blew. I removed the offending screw and everything now works fine.

As a side note, I (not knowing any better) used a 74LS08 at U18 and it works fine. Should I replace it with a 74HCT08?
