There Wren't many that didn't work and I am not sure why they - maybe from storage. Since I had no way to test them just ended the listings at time. It is expected that at least one will work but I am making no guarantees. Most of these machines were dismantled for mechanical issues and at the end their lifetime.
This Listing is for a set of 2 Modules, used but untested.They were removed from machines which decommissioned and dismantled. I have no way to test these modules and could find nobody who them for me. I have 7 of these modules left. They would basically be $20 for each module.
Purchaser takes full risk when purchasing this listing. If you would like more than 2 modules, ask me and I can make a special listing for.
