Does anyone know of a small, and hopefully inexpensive piece of hardware for converting NTSC video to Analog RGB? What I am hoping to do is to utilize this expensive Apple RGB monitor for more than just my computer graphics. With the right converter I should be able to use it as a TV when hooked to the NTSC output on a VCR. Could someone please send me the address of a company which makes a converter of this sort. Thanks in advance. ---- Joel Duerksen UUCP: <backbones>!{iuvax,pur-ee}!bsu-cs!duerksen -- ---- Joel Duerksen UUCP: <backbones>!{iuvax,pur-ee}!bsu-cs!duerksen

Thanks in advance. There are several ICs intended for the consumer electronics industry which do exactly this; the Motorola TDA3330 in their Linear and Interface Databook comes to mind as one example. However, you must realize that "NTSC" video also implies a certain timing - that used by standard television, which is basically 60 Hz interlaced vertical, 15.734 kHz horizontal. If your RGB monitor cannot accept this timing, and I suspect that it will not, then simply converting the NTSC video to RGB signals won't buy you anything. Bob Myers KC0EW HP Graphics Tech.
