operating system <<<

That's fightin' talk around here, so keep yer head down, laddie...

"Real-time" means simply "having a fast response from the point of view of the
process being controlled or examined".  A relay-based controller for a canal
lock can be considered real-time if it operates quickly relative to the traffic
using the lock and the flow of water.  It doesn't have to track incoming SCUD
missiles.

The CDI-605 development player makes a fair OS-9 engine and a good CD-I
development system.  Apart from the rather meagre processing power, the feature
list is pretty exceptional for a small computer.  Where else do you get a CD,
SCSI, EtherNet, digital audio, VHS quality video, support for run-length
animation and so on?
