older eagle and hummingbird fishfinders

[duke33]

No work today so I was out in the building digging around for a taillight. I found these two fishfinders. An Eagle Magna, that has what looks like an internal battery power supply..missing..and a hummingbird tcr 101 that is missing the power supply cable. They are brand new looking units. On the eagle i've found info on here that tells me to scrap it. The hummingbird website won't even recognize the tcr101....scrap it too? All I need is power to this old units. Surely some ole poorboy could use these. Any ideas on where to find parts..besides the normal eby and whatnot???

Edit. Looks like I can wire them myself, other than that they are obsolete....like me.
