There's nothing "authentic" or even remotely elegant about 78xx
regulators in my opinion. They're a current product, have been for
decades, and probably will be for another two decades.

"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? Having done PCI interfacing with an FPGA, I can say that
getting something working on an S-100 bus involves a whole lot less
