This is the Executive, or OCC2, which has a bigger screen and could take a hard drive in place of one of the half-height floppies. I was given this machine by Alan Hanks and his daughter Vikki several years ago, and with it came a box full of technical documentation, bundled software and even a 'beginners guide to the Osborne' which you could have standing next to you as you took your first faltering steps with this new little powerhouse of CP/M goodness! Thanks Alan!
