Creamware designed the first Scope PCI cards, they were smart enough to
allow for the DSP power of multiple cards to be combined into a total pool
for use by the Scope environment. Not everyone could afford a Scope
pro card with 14 or 15 DSPs first up, but they could maybe afford a
Pulsar2 one year then another the following year to give a total of 12 DSP.
Now, since it's not practical for two Scope cards to share the PCI bus in
order to be combined, Creamware added edge connectors to the top of their
cards, called 'STDM'. With this connector, the PCI Cards could be
connected together with a ribbon cable to form a single powerhouse.
Even today, the STDM cables are available from Sonic Core. This
article is for those that may be in an emergency situation where an STDM
cable may be required quicker than can be ordered / delivered around the
world by post, and so decide to make their own. There are also other
project situations that require non-standard cable lengths so this will also
