Since it was a reference design, the more OT examples
would probably be:
Tandy CoCo 1 / Tato Dragon (both based on 6809 reference design)
WD8003 and NE1000 Ethernet boards (The relevant NSC chip has
reference designs for both a memory-mapped and a port-mapped
implementation. The 8003 is essentially the former and
the NE1000 is essentiall the latter.)
<<<John>>>
The idea of a reference design becoming an industry standard's
got me wondering.
I know the NEx000 and WD8003 were cases of that.
The only other case I know like this was the WD1001/WD1002
which became the industry standard for hard disk controllers
in the ST506 days.
The WD datasheets pretty much gave you everything you needed for
the controller.
I can't think of anything else like this in the PC area. (Intel
didn't give you a reference design for the 80386 to build a clone --
although they made a large number of the chips available).
