Thank you for your interest in my 2:3 Scale VT100 Terminal Reproduction project

Are you sure? yes | no

Your VT100 console is a very cool project, and beautifully realized! One of my projects is the inverse of yours, a bartop arcade cabinet which can be configured as a terminal with a control panel swap, and I found it interesting that both projects tread similar ground while coming at the problem from opposite directions.
