Heya, Just in case someone has one they want to get rid of... Looking for a logitech 3 button C7 mouse. IT looks like this: https://www.retrogamingmuseum.com/the-collection/logitech-c7 I also am in need of a ISA Serial card. Single port is best, or one where I can disable the 2nd port + disable parallel. Going into a Tandy 1000SX. Note, the Bus mouse version of the C7 along with the BUS ISA card would also work fine. Could pay cash, or you can pick from my stash that I will bring. - Ethan
