I ordered a Dual opto from Digikey: MOCD207-MQT-ND which looks like it might
work but the backorder time is to 8-21-2000. It is manufactured by QT
Optoelectronics. The remaining duals were either not available or
backordered even farther down the line.
I guess I could string in 2 singles which would be ugly.
