Indeed, the black portable must have been DynaMac for sure. I can't believe similar would have been done locally, but who knows. I'll keep digging about this as well the Apple Macintosh "plus" built on Convergent Technologies-box. Seems that none of the old-timer mac-heads have even heard about this, so it should be rare.

The Bookcase SE is really cool no matter how it's been made or for.
