Radio Shack TRS-80 parts/hardware

Description

Radio Shack TRS-80 parts/hardware.
This is my grandfather’s leftover spare parts and hardware from his TRS-80 collection. As far as I can tell everything on the label for the box is here but I’m not 100% positive as I know very little about these machines. If there is an item listed that you aren’t seeing please let me know! The list includes:
1)UPI 2-3-4 (which I believe is the blue box with the power supply for the printer interface)
2) 3 knobs which I assume go to a dot matrix printer,
3)spare CTR 80 cable,
4)RS 232 connector cable brace,
5)crayon printer interface cable (which appears to have a small hole in the ribbon. See pics.),
6)old 4K ram from original computer
7)Jade 16k ram expansion kit. Blister is open (see pic) but I don’t know if it was cut open or just broke open after 40 years of storage.
8)LA38 Lever (not sure if that’s still here)
9)LA34 Knob (not sure if that’s still here)
10)Percom doubler II
11)alpha parallel printer switch (not sure if that’s here)
12)standard parallel printer cable
13)Gold plug connectors pkg of 6 still sealed
There are also several receipts and installation instructions and notes that my grandpa took regarding installation and modifications. Again, I’m not knowledgeable about these older computers and I have no way of knowing if these items work so everything is being sold as-is. Everything appears to be in very good condition for the most part and some items appear to be in their original packaging. I don’t want to sell these items individually so it will all be sold as a lot. I am also selling in a separate listing a TRS-80 multi-pak interface still in the box. Please contact me if you have questions or need more pictures.
