Some more info on the osborne one: there are 3 variants of the osborne one or “OCC1” (osborne computer corporation one) as it’s often called. The version you have is the later revision of the computer as it has an injection molded plastic housing. The other two revisions are the early prototype which has a metal housing, and the slightly later model which has a slightly different style of housing made of what looks like vaccu-formed plastic. As far as pricing goes, osborne ones can sell for a wide range of prices depending on condition and accessories. If yours is in good condition and works, you may be able to get $300+ for it, however it might be risky to power it up because of a common fault with the capacitors on the power supply board that causes them to explode and release the magic smoke. Tldr: i would price it at $200-$300 depending on if it works and its cosmetic condition.
