A couple of weeks ago, I acquired a "Jonathan" computer built by Akkord Technology in 1989. Complete with mouse, keyboard, display - and fully working. It's a Mac Plus clone (reverse-engineered) with some improvements. It's quite a bit faster than a Plus (about 15 to 30%), has two dedicated LocalTalk ports, and a Centronics printer port with real-time protocol conversion using a Zilog Z8. Apart from that, it has 4 MB of RAM and an internal HDD with 32 MB. Really a nice little machine.
Very few of these units exist, as Apple sued Akkord for copyright infringement resulting in the system never getting sold. Unlike other clones, this one seems to be completely forgotten over time. The unit I got was bought by the first owner directly from the booth of Akkord at CeBIT 1989. The second owner used it as a typewriter up to the year 2007! Since then, it was in storage.
I'm still in the process of restoring the system, so no pictures of the complete setup yet (keyboard and display still need cleaning). I'm posting more infos and pictures as soon as there's more to show.
