SPORTident printer serial cable

This cable connects the BS7-P printer control with the red SPORTident printer.  If you still have a BS7-P printer control, this cable allows you to continue using it.  Note that printer control must be reprogrammed to use a slightly smaller font.  See Eric's blog at http://sportident.ca and specifically http://sportident.ca/archive/2025/05/09/setting-up-bs7-p-for-the-red-sportident-printer.aspx
