RoC equals Rules of Comduct. And you should care because those are the codes to which you are bound to by participating on Pilots of America.
I will have to decline thank you. You are low balling me on that offer I would like it if you please erased the post you wrote as to not taint the potential buying field with your offer. I have seen it and will gracefully decline thank you
My offer for your item is $15.00 including shipping to my Texas address (money via PayPay) for the calculator including the case and instructions as shown in your first photograph. If the case and booklet are missing or in poor condition, I will return the items and cancel the PayPal.
And I'll add comments about my offer: This unit is from the mid to late 1980's and does have a small amount of historical interest from me and I would like to have it as part of my aviation collection. But I am not willing to pay a price that exceeds today's electronic flight computers.
