[Drake] Readout for twins?

[TJRachwal]

Hello,
	Many years ago I had the T$x and R4B setup with a "neat" black 
digital readout ...red numbers I believe.  It was really slick and 
simple to install (made commercially) but I can't remember who or 
what the name/model was.  I have a friend who is looking for 
something to give his R4C a digital readout.  Can anyone remember the 
name of my old unit or suggest a newer readout  (external) for the 
twins?  Help would sure be appreciated.
