Unidentified Apple Plus like computer

Hi, I just aquired this 1986 Apple Macintosh Like Plus Portable / Luggable Industrial Vintage Computer.

I don’t know much about this machine other than it’s based on a 1Mb Macintosh Plus machine, it’s completely custom made in around 1986 and it does not work.

The machine itself is really unusual as it’s built to a really high finish with injection moulded plastic and really finely cut steel and aluminium, but it doesn’t have a single label on it - nothing to be able to tell who made it and why.

Inside there is a Macintosh Plus motherboard and analog board, with a custom adapted SCSI hard drive, floppy drive and some controls such as reset and either volume or brightness. There is also a serial output on the back, which suggests this had some kind of industrial use.

Has anyone ever come across one of these?

Thx. Jsth42
