Instek Oscilloscope Training Board

[gfmucci]

Is anyone familiar with or used this board from Instek?  Decription says it is for 2000 and 3000 series Instek scopes.  I'm wondering how useful it would be for Insteck 1000 series, or for any other brand scope.  I've concurrently sent this inquiry to Instek.
