STEBus




STEBus Description

STEBus defines a bus with a 8 bit data bus running at TBD MBps, with 20 address lines.
The connector used by IEEE Std 1000 Bus boards is a 64-pin male connector utilizing the outside two rows (designated a and c rows).
The connectors are specified in IEC 60603-2, and the mating female connector is used on IEEE Std 1000 Bus backplanes.
The recommended size for IEEE Std 1000 Bus boards is 100 mm x 160 mm (3,937 in x 6,299 in), single height standard depth Eurocard.
Double Eurocard Boards and Modules are also used.

This bus went obsolete in the 80's and early 90's.




STEbus Standards Information

IEEE Std 1000-1987: IEEE Standard for an 8-bit backplane interface, STEbus
IEEE Std 1101-1987: IEEE standard for mechanical core specifications for microcomputers
ISO/IEC 10859: Information technology, 8-bit backplane interface: STEbus and mechanical core specifications for microcomputers
ANSI/EIA RS-310, Racks, Panels, and Associated Equipment. [Rack Manufacturers]

Note that the STEBus standard was last updated in 1987.
Normally a standard is updated every 5 years, when the standard is active and work is on going.



STEBus Interface IC Vendors

STEBus uses normal [+5 volt] standard TTL switching levels VIH = 2v, VOH = 2.4v.
