One of my neighbors threw out a Radio Shack Service Manual for the TRS-80 Model III Microcomputer.

I have a Model III in need of serious cleaning and repair, inside and out, thanks to the seller shipping it with so little protection that what few packing peanuts it had invaded the cavities of both disk drives.

Dumpster dive finds like this are great and all, but being reminded of just how much treasure that's trash to other people makes it to the landfill saddens me.
