Speaking of the Signetics 2650, does anyone have
anything about the Signetics
TWIN (e.g. manuals, schematics)? We have a bare system without floppy drive,
but with a bunch of hard-sectored floppies that I have just dumped. They
containt mostly SDOS related stuff, e.g. system sources, Pascal compiler etc.
Is there really nothing? I'm especially interested in the floppy
interface. I suppose that the external drive box contained the controller
that attaches to the master CPU board. Since I don't have the drive box
(nothing except the base system) I can't revive the system at the moment.
