<DIV>The request for a machine to play both PAL and NTSC has led to an
interesting discussion.</DIV>
<DIV> </DIV>
<DIV>I did some research and found that the universal Colortec works in both Pal
and NTSC. This solves the TBC problem. </DIV>
<DIV> </DIV>
<DIV>The VR-1200 is a more difficult machine but has advantages.</DIV>
<DIV> </DIV>
<DIV>The AVR-2 is a beautiful machine. It does not do multi
standards.</DIV>
<DIV> </DIV>
<DIV>To change an AVR-2 between NTSC and PAL requires a lot of
board changes. </DIV>
<DIV> </DIV>
<DIV>Board 2 Capstan Servo</DIV>
<DIV> </DIV>
<DIV>Board 3 Control Track Processor</DIV>
<DIV> </DIV>
<DIV>Board 12 Modulator</DIV>
<DIV> </DIV>
<DIV>Board 15 Switcher and Equalizer</DIV>
<DIV> </DIV>
<DIV>Board 16 Demodulator</DIV>
<DIV> </DIV>
<DIV>Board 17 TBC Video Input</DIV>
<DIV> </DIV>
<DIV>Board 20 Clock Generator</DIV>
<DIV> </DIV>
<DIV>Board 22 Memory</DIV>
<DIV> </DIV>
<DIV>Board 23 Two line delay</DIV>
<DIV> </DIV>
<DIV>Board 28 Logic</DIV>
<DIV> </DIV>
<DIV>Board 29 Sync Gen Logic for PAL only</DIV>
<DIV> </DIV>
<DIV>Board 30 Sync Gen</DIV>
<DIV> </DIV>
<DIV>As you can see there is not an easy solution to use the AVR-2. It is
the easiest machine to use, and you can get very good pictures. I would go
for it is all one is doing is a single standard and High Band only. If
not, then you are stuck with a VR-1200 series. </DIV>
<DIV> </DIV>
<DIV>Hope this spreads some light.</DIV>
