RAIR microcomputer
Black Box

RAIR was a very early UK manufacturer of 8085-based systems and eventually licensed its designs to ICL.

This obscure system was sold with a hard-disk and a 5"1/4 disk-drive built-in. It was conceived to be used as a multi-user system.

The following languages were available : Basic, Cobol, Fortran, Pascal, PL/1.

More information about Black Box internal hardware in the ICL Personal computer page.

Pictured here is a model 3/30.


Douro says:
This machine uses a Seagate st506 hard drive; I am quite certain that it could use many different drives through the interface.

John Pettitt adds:
Later black boxes were 8088 based and used hard disks up to 15MB.
RAIR was the first company in Europe to ship a 5.25 HD and the second world wide.

Mark Sharples reports:
The boards on this model would sometimes come free from the mother board during transit. The engineer would arrive from Rair, wait for the client to leave the room, and then simply drop the computer from about two inches off the desk to re-install the system.
