[comp.sys.handhelds] HP48 Serial Interface

stoppani@rust.zso.dec.com (Pete Stoppani) (09/14/90)

Could someone please send me the technical details of the HP48
serial interface/cable?  I need to know what wire does what and
the voltage levels used.  A friend is going to build an RS232
interface for my ICOM R70 receiver so we need the HP48 interface
data.

Thanks in advance,

Pete Stoppani
