The following link has some information on the SPO-256 chip including PDF's of the GI and Tandy spec sheets.

I'll chip in (!) here and mention that Radio Shack was selling these chipsets many years ago. I even went and bought one. I could never get it to work reliably over the serial interface because it did not generate XON/XOFF properly. I remember fiddling with it for long hours, and I found that it generated an XON character for every character you sent to it, until some internal buffer was full, then it stopped sending XON. Does anyone have a data sheet on these chips? I was following Radio Shack's experimenter's data sheet, which may have been abbreviated. I'd love to get this thing working. -- James Cameron mailto:quozl@us.netrek.org http://quozl.us.netrek.org/
