No luck on any number.
I talked to someone on June 13, 2020 around 3-something p.m. I ended up disconnecting about 10 minutes in, when he thought I had taken off the computer’s front cover and was going to tell him what the operating system was. At least he did not spend 10 minutes taking advantage of an elderly person, They normally hang up early-on, when I say I am using a Radio Tandy computer, my browser is Netscape, and I cannot see a “Windows” button.
