"Authentic"--yes.  They were on almost all original S-100 boards.  
Which was my point.  There are lots of great regulators now--
particularly the buck/boost models, but they wouldn't be "authentic" 
to the S-100 era.

At the time of the S-100 bus, there was already a better bus--
Multibus.  It outlived S-100 by a very long time.

If you want simple, try STD bus.  But then, even ISA/PC-104 will do 
just fine for S-100 speeds.
