Hi All. I've become curious about the different DECTalk devices. There seems to have been a number of variants. The stand alone DTC01, a UNIBUS version and a PCI card version (DTC07). Do all these sound the same? Or are newer ones more advanced? The number (07) on the PCI version indicate that there has been at least seven versions, what are the others? And finally, does anyone have system over and would consider selling it? (DTC01 seems to be the simplest and is thus preferred) Regards, Pontus.
