VT420, only toasted

I bought two of them despite the nasty burnin today. Took them home and plugged my LK401 I wanted to test into it and turned on the power. Wow, the burnin looks very nasty with the old library screen easy to read WITH THE POWER OFF, with the power on I don't even notice it except during the power up when it does the big checker board tests, and then its marginal, not nasty. What do I need to do to put the VT420 into local mode? It powers up, does some obvious testing like the checkerboard screens (big than little), and finally says something like VT420 OK, no printer connected. Nothing seems to make a difference until I hit Return, then I get a prompt at the top left and a line at the bottom. So how do I get to setup mode to set it to local echo? Does this change interest in them? When powered on they have what appears to me so far very usable, if not "nice" amber screens. They don't "seem" very heavy either, but I haven't packed one and put it on a scale. Keyboards are doubtfull, when I left another guy was trying to buy all of them, but I will know for sure on Thursday. Assuming I can't get keyboards I am willing to buy a VT420 and pack it for $12 plus whatever the actual shipping is. No variation on a normal box is going to hold a VT420 and a keyboard anyway, so might as well keep them separate with a LK401 keyboard at $10 plus $7 shipping IF I can get some. Some of the units have a velcro attached glare screen, most have a short dongle with a weird RJ11 socket. There were also a few VT320 displays, but I haven't looked that closely at them (same burnin look though). This Thursday will likely be my last chance at them, as a big load is coming in that day, and I will be in Silly Con Valley (yes really) next week (8/1 to 8/3).
