IEC Port Expander - Back

I picked up this beauty at ECCC. This is a port expander for the IEC Bus - it has one input for a Commodore computer and can control up to four other IEC devices (such as disk drives, printer, uIEC, etc.). The first switch turns on/off burst mode and controls the input reset. You can turn on / off the ATN/RST of any of the four devices with the other four switches. The push button resets the devices which are on. See the next picture for the front.
