The ones I've had, and still have one of on my coco3, are a tech I don't identify, but it has the same 9600 baud interface as an older crt model we used on the weather gfx terminal 15 years ago at the tv station. On a db9 connector. If I had more serial ports, I'd be tempted to see if I could adapt my "joystick" driver that runs with a serial mouse to it. But its ex P.O.S. from a grocery chain and might be 14" diagonally, a bit small for good control of LCNC. $64 from fleabay 3 or 4 years ago. I have a scan doubler between the coco3 and this monitor. The old, must have been 75 lbs, 15" crt model has been recycled long ago. > > -- > > Cheers, Gene Heskett > > -- > > "There are four boxes to be used in defense of liberty: > > soap, ballot, jury, and ammo.
