Hello. We have several DEC VT241 Color Terminals. I want to use the color monitor that comes with the terminal in a separate application. I need technical information on the monitor itself, primarily: 1) Vertical Scan Frequency (MHz) 2) Vertical Retrace Period (milli/micro Sec) 3) Horizontal Scan Frequency (MHz) 4) Horizontal Retrace Period (milli/micro Sec) 5) Is the monitor interlaced? (# frames) 6) Is the monitor TTL or ANALOG RGB? 7) Any other info needed to set up an MC6845 CRTC to work with it. DEC's name for the monitor itself is VR241 and they want $165.00 for the technical documentation for it. If anyone can tell me the above specs it would save me lots of money and will be very helpful.

They will work at the normal NTSC scan rates, and I suspect that they may have some "multi-sync" capability for the 132 column mode, but I'm not sure. It is an analog RGB monitor with composite sync and will work directly with an Amiga. It also has a Japanese manufacturer's label on it which might relate back to a specific generic monitor family. >DEC's name for the monitor itself is VR241 and they want $165.00 for the >technical documentation for it.

Re: VT241 Monitor The DEC color monitor and the Japanese Amdek Color-II monitor are VERY similar inside; the connectors on the back are different. Schematics are available from Amdek, and possibly Sams Photofacts. Frank Reid reid@gold.bacs.indiana.edu
