DIY_EFI Digest V5 #74 Re datalogger

[Pat Ford]

 I'm looking at making a datalogger myself, does anyone have
a circuit laying around? I'd like 8 ch ADC 4 eca ( counter timmers)
and 8 digital inputs. The output would ideally be to a serial port.

 So before I reinvent the wheel anyone seen a kit or schematic for
such a beast??
