Hmm...that could be it!

I spent quite a while trying to determine exactly what kind of computer keyboard the Wookiees are using for the family terminal that looks a bit like a TRS-80. In the end, it didn't resemble anything exactly that I found, so I think it was either something amazingly obscure (and I looked at some pretty obscure ones) or it was some kind of composite cobbled together from various things.

I actually have one that I just removed the label from and it has the same covering over the reels as the prop.

I'd really like to figure out what Lumpy's viewer was made from. It looks like it could be a modified portable 8 track player, but I don't know what brand it could be.
