I am currently operating a VT1000 terminal with the ROM update kit provided by DEC. Just recently the monitor for the system which is DEC product number VR262 was smashed at a computer show. DEC informed me that they will not replace the picture tube and suggested that we purchase a new one. Several third party services explained to me that they will replace a picture tube, but cannot obtain a the correct part for a VR262. What our comapny did have available is a couple of VR260 monitors that where not being used. The only problem now is that the VT1000 is not 100% compatable with the VR260. The picture is a little warped and slightly twisted. Does anybody know where a cheap picture tube for a VR262 can be obtained? Is there an adjustment that can be made to the system which will straighten out the picture? Any response will be greatly appreciated Rich Wernick wernick@venus.clearpoint.com

Does anybody know where a cheap picture tube for a VR262 can be All 5 of our VR262 monitors show "warped and slightly twisted" pictures. We convinced DEC to try replacing one of them (twice) to no avail. If anyone knows how to get these things looking good on *any* setup (VS3100, VT1000), please let us sufferers know! (Yes, we've removed them from any nearby RF sources and placed aluminum/copper shielding with no appreciable effect).

Access could be gained by taking the cover off the monitor (four hex screws in the back) and then sticking a long thin screwdriver down the appropriate holes along the top of the monitor (they are labeled). I've got to believe that something along these lines has been provided on the VR262, although a quick look through the plastic case on mine shows that the access holes are not in the same place. Using this method we've been able to reduce the distortion on the tubes, although it never goes away completely. I'm surprised your DEC rep didn't do this before replacing the monitor. ============================================================================== Jon Geld | geld@mail.physics.lsa.umich.edu Sys Mgr, Physics !
