[QuadList] High and Low band on AVR-2 via new board set (was Multi Standa...

[Ted Langdell]

Given the differences between an AVR-2 running NTSC and one running  
PAL, one machine for each line standard seems to be the simple way to  
go.

Fortunately, Shai's not likely to run into 405 or 819 line tapes in  
Israel.
