How about using a PC and the sound card. Yes, it is analog, but you might b=
e =

able to produce an output that looks digital by creating an appropriate WAV =

file. Run this through an appropriate amplifier and a digital buffer that w=

give you the right digital levels.

If you don't find an appropriate software that does what you want, perhaps =

rolling your own using the parallel port instead of the sound card might be =

easier. The digital output train could be configured with a textfile.
