mdorantes,

Those extra 12 floppies and OS were intended for the SD1 and not the SD1 Plus. The 12 floppies are the New Sounds (already found in the SD1Plus) needed to convert a SD1 into a SD1Plus.

Send me an email to ketron_tech@yahoo.com so I send you the correct OS for your board (which is actually an SD1Plus). However, you have to be carefull as you have a SD1 Plus CPU baord but might still have an SD1 Sound board which is why the SD1 is not booting up!

Again, we can continue this discussion of-line.

Thanks,

AJ
