Same Zilog 8530 (8350??), same mini-din 8, same RS-422 signals... I think using the serial port would be the way to go, since using the Ensoniq would really defeat the purpose... Anyways, how would you go about doing this? The Cedar digitizer outputs serial info, and it would be weird, although probably not impossible to use the Ensoniq to digitize that serial data!??! The sound connector has 3 pins that determine the output channel, 1 ground, 1 analog input, 1 pin analog output and 1 that says when the channel number on the 3 pins is valid, I think. There's no serial input, so it would be strange to hook the digitzer up to the Ensoniq... Anyways, the Ensoniq is subject to all the noise inside, while a external shielded box would be immune to this. > The software will obviously have to be re-written, but that would >be the case whether or not it used the serial port. Yeah... does anyone know how to get the SCC to go faster than 19.2Kbps? I know you have to write to the registers somehow... >-- > -- David Huang | Internet: daveh@ccwf.cc.utexas.edu | "Slight accidents with funny rays UUCP: ...!ut-emx!ccwf.cc.utexas.edu!daveh | can have serious consequences" America Online: DrWho29 |
