I have some different boards and parts that are taking up space, most non-working and can be had for free plus shipping if you're looking to hone your soldering skills or scavenge parts; all prices not including shipping:
8-Driver PCB from STTNG (A-16100) - has been repaired twice (Q1 replaced both times), some traces lifted at Q1, currently not working - FREE
Eddy Sensor PCB from RS (A-18543-2) - started registering hits to the bulldozer all the time, the pot no longer works to adjust sensitivity - FREE
Power Supply PCB from BTTF (520-5000-00) - has been repaired by the previous owner, currently works - $50
"Danger Bridge Out" Ramp Entrance Gate from RS (A-19311) - missing Wig-Wag PCB, cracked plastic, frame still intact with wire gate - FREE
Feel free to contact me if you want some pictures.
