NatSemi Simple Switcher regulator board. Can be stuffed with different parts to get different output voltages and current ratings. The point is to efficiently power 5V/6V/9V devices from a 12 V lead-acid battery.

SEPIC DC-DC converter. Takes an input of 8-16 volts and puts out 12 VDC at up to 2A – so it’s useful for powering small 12 V devices from a lead-acid battery, whether it’s at full charge or close to dead.

DLV11J DB25 adapter. Works instead of a DEC cab kit on a DLV11J or anything else (like some PDP-11 CPUs and CMD SCSI controllers) that uses the same 9/10-pin Berg pinout for the serial port.

DLV11J to USB serial port. Same as the DLVDB25 except that it includes an MCP2200-based USB serial port, so it works with new PCs (which probably don’t even have DE9 COM ports any more and certainly don’t have DB25s).
