[Coco] Introducing the next generation of Color Computer, the CoCo-X

[Aaron Wolfe]

USB on servers is rarely the same concern that it is on desktops
because servers are (or should be!) physically secured against
tampering whereas it is impractical to physically secure a desktop.
Instead, usb is disabled using bios settings or via the operating
system (in windows environments using group policy or a third party
add on).  Some security products can allow usb HID devices without
allowing mass storage or other devices that should not be permitted on
a desktop, but it's easier to simply disable USB altogether and use
PS/2.  That's why you will find PS/2 ports on most "business class"
desktops today.  Servers also usually have ps/2 but that is more
because KVM switches tend to work better with PS/2 than with USB, not
so much for security.

The important point is that PS/2 keyboards are still easy to obtain
and will continue to be produced and sold for the foreseeable future.
New models are available from all the typical peripheral manufactures.
