D I am absolutely amazed at what the new display enhancer does to standard Amiga graphics screens. Even though Shadow of the Beast does not work with my A3000, I get some of the initial screens (check out the screen that looks like the box cover w/ and w/out the disp. enh.. WOW!!). Now, I own a CMI VI-500 RF converter and have used it with an A2000 to dump Amiga graphics to video tape. I know that the A3000 has a 23 pin connector to which I could hook my encoder AND I also have 2 connectors which came with my A3000 which will convert from the connector for the 31 KHz out to a 23 pin connector. So I have a couple of questions. One, does the display enhancer affect the data output on the standard 15.?? KHz 23-pin connector on the A3000? If not, is there ANY reason (such as "the CMI cannot handle 31 KHz") why I cannot use the 31 KHz to 23-pin converter to hook up my encoder to the 31 KHz out so that I can dump these display-enhanced images to video tape?? This would be a MAJOR Boon for the Amiga video market, since the images NOW look much better. Are the images processed with the display enhancer NOT NTSC compatible??? Any information on what can and cannot be done w.r.t. this stuff would be appreciated. I am sure that a lot of potential and current A3000 owners would be interested in this information. Thanks, Scott Sutherland sutherla@qtp.ufl.edu

The A3000 Display Enhancer's output is 31.5Khz and is NOT recordable on any VCR since the VCRs must have 15.734Khz video. Sorry but it is a no go. Hope you enjoy your new A3000!

No, you have an adapter that allows the 15-pin VGA cable from the A1950 monitor to plug into the 23-pin connector. The adaptor does not create at 31 KHz signal - it buffers and passes the 15 KHz signal to the monitor, which is capable of displaying an image at that low frequency. >One, does the display enhancer affect the data output on the standard >15.?? KHz 23-pin connector on the A3000? No, it does not. >If not, is there ANY reason why I cannot use the 31 KHz to 23-pin converter >to hook up my encoder to the 31 KHz out so that I can dump these >display-enhanced images to video tape?? The adapter only passes signals from the 23-pin end to the 15-pin end. It can't be used backwards. >Are the images processed with the display enhancer NOT NTSC compatible??? You got it. NTSC runs at a horizontal frequency of 15.750 KHz and a frame rate of 30 Hz. The display enhancer puts out a signal running at 31.500 KHz and a frame rate of 60 Hz. That is very definately out-of-spec for any NTSC compliant device, such as your CMI Encoder, your VCR, or your TV. -- Joe Smith (408)922-6220 | SMTP: jms@tardis.tymnet.com or jms@gemini.tymnet.com BT Tymnet Tech Services | UUCP: ...!{ames,pyramid}!oliveb!tymix!tardis!jms PO Box 49019, MS-C41 | BIX: smithjoe | 12 PDP-10s still running!
