You can take an old PC/AT/386 with a 'supported' sound card and write a
small program to read the samples and write them to the serial port.
Continuing on that theme, you can put the samples out an ethernet card
for more bandwidth.
It is worth mentioning that MOST old soundcards have 'anti-aliasing'
filters, whereas MANY motherboards and PCI sound cards do not!!
It is well worth the time, once you are up and running to take a signal
generator and 'sweep' your soundcard to make sure that out of band signals
