[sdiy] DR-110 trigger outs

[Dave Magnuson]

Hi List,

I'm adding trigger outs to a DR-110.  I'll be converting the negative-going
triggers from the CPU to positive triggers with a CMOS 4049 inverting buffer.

The DR-110 trigger pulses are 1ms long... should I use pull-down resistors
at the input of the inverters?

Thanks in advance
