[comp.sys.amiga] A3000 genlock trouble

jheald@hydra.unm.edu (Jerry Heald ) (09/08/90)

I hope someone at Commodore will contemplate a compatability problem with the
Amiga A3000 and the Scanlock genlock. Hardware specifics are A3000/25/100 with
KS2.0 ver 36.141 & WB2.0 ver 36.68 and the A1950 monitor with the display
enhancer on. The Scanlock is the model VSL-1. The Scanlock depends on the
A3000 for power.

The problem is the entire display shifts left to right about 1/16" several times
a second, but not at a uniform frequency. I am talking about both the A1950
display and the Amiga graphics on the destination VCR and video monitor. This
happens regardless if the source sync signal is live TV or a black striped
S-VHS tape.If the external sync source is shut down and dependance is on the
Scanlock for sync then the Amiga graphics on the destination video monitor is
stable but the A1950 display is trash.

This left to right shift may not start for the first 5 minutes of operation,
perhaps as long as 20 minutes. Once it starts, it seems to continue
indefinately. A power down and restart may yield a stable display again for
a few minutes.

The Scanlock produces a stable display with my A1000 and my A2000. What is
going sour with the A3000? This shifting of the Amiga graphics from side to
side is not acceptable! Please investigate. I can supply a tape of the display
if that would help. This problem is negating what is supposed to be one of the
outstanding capabilities of the Amiga.
