That was definitely a bargain and you would have been crazy to refuse that. It is going to be a very nice machine.
Are you using TurboCAD????? Are you serious? I thought I was the only one using that 16 years old software. Works nice under W10 and I am very happy with it. The installer stopped working already when XP Pro was released, but that's not an issue, just makes installing a bit more tricky.
