Offering a Mr. Do PCB by Universal from 1982.

 

I have verified that all socketed PROMs & EPROMs are good and match to MAME.  The Z80 CPU has been independently tested and is good.  I used an adapter and connected this PCB to my JAMMA test set up and get no response at all.  No sound, no picture, no playing blind.  Assume the worst, not working (proven), parts missing, physically damaged and then anything better will be a bonus for you.  I don’t see any obvious damage.  Please review the pictures carefully.  I do see evidence of previous repair.  Some IC’s and other components have been replaced.  I do not notice any corrosion or rust on this PCB or edge connector pins.  The edge connector looks excellent.  There are no unpopulated sockets.  This is a genuine Universal board set, it is not a bootleg.

 

All sales are final, no returns.  Be sure to check voltages before installing.  Bad voltages may damage the board.  I am not responsible if the PCB is installed incorrectly or in a set-up with incorrect voltages.

 

What you see in the pictures is what you will get.  These are photo(s) of the actual item you would get.  They are not stock photos.  Note:  Any pictures showing testing, the test set up is NOT included.  The voltage read-out tools are NOT included.  Just the PCB.

 

You are welcome to view (and try if applicable) this item in person and pick up in person to save all shipping costs.  If you have any questions or would like any other pictures, let me know.

 

I am offering several other one-off, PCBs.  Please see my other auctions.  I am happy to combine shipping if you buy multiple items from me if they are somewhat close to the same size or will fit together into one larger box.
