There's nothing "authentic" or even remotely elegant about 78xx

"Authentic"--yes. They were on almost all original S-100 boards.
Yes, that's why I quoted "authentic". There's nothing (IMO) about
the presence or absence of a 7805 that makes an S-100 board any more
or less authentic...that's the point I was trying to get across.
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.
Very true.
"Better" is subjective...Better for what application? If you're
designing a small system for, say, industrial automation, do you
really want the expense and extreme complexity of something like PCI
or VME?
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.
Also true. I'd bet, however, that the number of S-100 products is
twice that of Multibus and STD bus combined, even when taking into
account stuff like Multibus-based Cisco routers and related stuff. I
wonder why that is...is it just a matter of having been developed
sooner?
