Refer to my previous message. > Please clarify if such is true! Clarify a source. Allan Bairstow. Can't be more clear than that. Clarifyingly yours, Robert Bernardo Fresno Commodore User Group http://videocam.net.au/fcug P.S. Do you have Allan's phone number? I can give it to you, and you can talk to him on the phone.

If the C=VGA works Works on my aussie gear, the monitor is a 1084SP1AU. He should also try the VIC experience side - it messes with VIC timings and palette.... But yeh, if he could get Risen from Oblivion working 100% on this thing Ill be interested. I just bought a flyback to fix my spare 1084S tho :)
