Trying to get info on very old portable computer

[DudeMiester]

I've searched and searched, and this is the only online reference to this old (1984) portable computer I have at my house:

If anyone know anything more about this thing, mind giving me some hints? Like is it worth anything? I have all the manuals, software and everything.

a lot of old portables have some value, i'm not sure if this thing will rank up there with the Apple Lisa 1, got any collectables shops around?
