Vintage Corvus 411 Calculator Slide Rule Functions Perfectly + Adapter, Minty!

Description

Thanks for checking out my Corvus 411Slide Rule Calculator.  I am the original owner! I used it for a couple years and it has spent most of its life in storage.
This unit is in really nice condition.  The screen is clear, bright and contrasty.  There are no defective pixels or dead spots.  It produces a nice, clean display.
All the buttons are functional as they were designed to be with no stickiness or hangups.
Cosmetically the case is in nice shape with no broken parts or scratches.
The rechargeable battery pack is no longer functional, this unit works fine with the included original power supply.  It also comes with the user manual, Case and original packaging box.
Please check out the pictures and feel free to ask me any questions.  Please buy with confidence.  I will gladly accept a return, if you ultimately feel it isn't going to work out for you.
Thanks,
Johnny
