Coleco UFO Pinball?
« on: January 14, 2007, 07:52:50 am »
My parents just received this for free..  Non-working..

It's a Coleco UFO pinball machine..  The playing field is around 19" x 32"..  Only one pop-bumper in the middle..  Definitely for kids and such.  It appears to be missing the power supply.   And we're not sure what voltage it requires..

Attached are some pictures.  Anybody have any information on it?  Or know where information might be found?  My girls would love to have something like that to play.  And it would look 'cute' next to my dad's 2 other pins  :)

THANX!

It only has one small PCB in the backboard, so it shouldnt' be hard to reverse engineer that thing and get it running again.

Does it get anything out of its power supply?  Show some pics, we can start there.

:)

If we knew what kind of PS it took, we'd have more of a starting point..   :) 

The pics I attached are all I've got from him..  Any other pics that would be helpful, please let me know.  My dad's got the day off, today, so he should be able to snap more pics for me  :)

THANX!!

Don't know how I missed that.  Get a closer look at that PCB.  Bigger pics in general would help as you can't really see much in those attachments.  Not enough to do what we need here, anyway.

Not great pics.  Unfortunately, I'm 4 hours away and can't do this myself  :)  My dad (and some of his friends) are good with the electronics and such, though, if they have the right info  :)

Let me know if I should have him take the pcb out and try to get better ones.  Any thoughts?  Looks pretty simple, but I'm a software guy, not a hardware guy  :)

Thanx!

You're right, you can't tell much of anything from those pics except for the very primitive nature of that PCB.

The PIC1650 is an early microcontroller chip that with a supply voltage of 4.5 to 7 V according to an old data sheet.  Look for the power input point and see if it is rectified or not at the input.    If it is not rectified then the PS was DC.   If it is rectified then the input was AC.    See if there is a series regulator arrangement or any parts that look like transistors where the power comes in.   There could be a 3 terminal regulator that looks like a transistor at that point.  Look for a larger sized electrolytic cap to indicate DC smoothing.    If there is no signs of regulation or rectification then the power input has to supply the microcontroller chip with DC from 4.5 to 7 V.    Also look at the light bulbs to see what number they are and check how they are driven.

There are alot of little hints but you will need clearer pictures of the PC boards and some indication of where the power is fed in.

But I've passed on the comments and will see what happens  :)

as we have already found that the chip supports 4.5 - 7v I would attempt powering it up off a 5v supply

Not yet.  Identify that transistor type package on the corner of the board.  If there is a VR there, that is it.

Agreed.... identify the transistor in the corner circled in blue.
(see below)

I would assume power is to come in on that connector just to the right of it as.
Assuming part of that connector harness goes to the front for flipper/playfield controls and part of it being used to supply power to the board. The other smaller connector appears to run just the headbox.

What all is attached to the larger connector?
Just curious as to if there is a power supply "plug" or "socket" somewhere on the body, for like a transformer style wall plug.

A transistor can be part of a series regulator circuit.  It does not have to be a discrete VR.

There's only one small cap there, though, which makes me think it's something else.  It's definitely not part of a rectifier circuit.

Really we are just guessing without a clearer picture and indication of where the power is supplied.   Another help would be a picture of the traces on the back of the board.   

If it is a DC to DC regulator a large cap is not required only a voltage ref such as a zener diode.   The caps only smooth the AC to DC regulation.   When a discrete VR is used check the sample circuits and you will see that a large cap is not required only a small value cap to pass transients.

If it's a DC to DC regulator, and assuming that it's not missing another PCB, it would have to be a wall wart transformer, yes?  I'm not questioning your responses, I'm exploring my own understanding of what could be present and moreso what could be absent.

I am assuming a wall wart because it reduces the level of hazard when wiring the game.  Any of the haphazard looking wiring would not stand up to ULC standards for 120V.  So if the lights are 6V we can probably get along with 5 to 6 v.   If the bulbs are 12V then some sort of DC to DC regulation would probably provide the 5 V for the PIC and the 12 V would be direct from the wall wart.

We need clearer pictures to move from the guessing stage to the actual get it working stage.   

Glad you are enjoying the wordy analysis Chad.   I am always open to comment as it makes me think and dig deeper.

If he can give us a reasonable estimate on the gauge of the solenoid circuit wiring, that will probably tell us a lot about what type of power that's sucking.

When did it become regulation to list power requirements on devices? (I'm wondering if this toy pre-dates that time or not). Usually if you check the back or bottom of a device like this, it will list power input ratings for the jack (assuming there's a jack).

Next thing is, check the OTHER side of the pcbs. They could be blank, or they could be marked with more information. (For example on this visible side, we see markings like "C1" which means Capacitor. "R1" means resistor, etc. There might be a voltage indication somewhere).

Given the age of that PCB, and the fact that it's brown, would tell us that it's likely single layered and not throughholed.   If it works with a wall wart, though, it would definitely have (or had) a jack someplace on it.

A quick google and found something on ebay that would date this one to be around 1978.

I didn't "see" it on that side of the fold-out...... probably on the other side. But the seller specifically mentioned that one in his list of games in the catalog.

The grid designation on that Tip120 answers our regulator/transistor question... it's a transistor.

Next question:  What's that big rectangular trace looking thing at the bottom right of the green side?  I don't see any traces connected to it and there is nothing connected to it on the topside.  That looks like it's missing something.  If it were a screw located ground point then it would have traces to it, yes?

The only way to tell, I guess, is going to be to buzz it out.  The easiest way to figure this sucker out may actually be to watch ebay for another one that is complete.  Can't cost that much and would be worth doing for the hell of it.

Looks like a board ground.  The pad is connected via a jumper labeled WJ3 on the topside of the board.  Followed the trace to the PIC but it is hidden my the disk cap.   Looks to be going in the right direction to hit the ground pin of the PIC but cannot tell for sure.

More info from my dad (before I realized you figured out the one area...)

Quote
jas, on the top side there's a "jumper" that goes from the big
rectangular trace to about the 5th trace in (you might be able to see
the solder connection on at about a 90 degree angle to the
rectangular trace.  it's straight over from the top of the large
trace.)  on the pinball machine a screw goes in the hole.  located
between the screw and the plastic support on the pinball machine is
about a 1/4" wide thin piece of brass about 3" long.  It extends
straight down from the board.  connected on the bottom end of the
piece of brass is a piece of steel about the size of a nickel. 
located behind, but not touching the "nickel" is a screw with a wire
attached.  the wire runs up around and it looks like it connects to a
capacitor.  the whole thing reminds me of something that would
activate a "tilt".  don't know if that's it electrically, but that
sure has the look of it mechanically. 

the capacitor and wires are the only real electronics i see external
to the board.

THANX!

Having gone over the pictures of the pb machine a couple more times I do not see any obvious place where power could be brought into the unit.   Is it possible that it is a battery operated toy?   Maybe the batteries leaked and the holder has been removed.   Just an idea.

Is there a closer pic of the bottom?
I'm curious as to the red and black leads on that six pin connector.
Old school theory of red/black being power and they "appear" to be cut off on the underside. (but I'd like to verify)
Or do they run any lights on the playfield?

Zooming into the pic shows to me that the red wire goes to the play field plate and the black wire goes to the motor in the middle of the play field.  I am guessing the the pinball is what closes the circuit for the scoring mecinisim.
