Maybe I'm misunderstanding something, but why not apply a layer of tape immediately on top of the conductors - since a thickness of .X of a mm (through) will insulate 22KV, Y mm (across - where Y is the distance between the conductors) definitely ought to do it. Although there is the glue that holds it down - I wasn't sure if that was the glue you were referring to, or if you meant some other glue - that might not be as insulating (or maybe it is, just don't know). But, anyway, if the glue might be an issue, you'd have to apply the tape non-glue side down (and stick something like regular electrical tape to it, glue-glue, to nullify its glue on the now-up-facing side - unless you want to use that to join the two layers of the original together). As to how to get it to adhere: if you can figure out what the insulating glue was that they used originally, or some modern facsimile thereof, you could use that. Noel

Those 2 statements partially contradict each other IMHO.

Provided my next-of-kin gets to hear about it in time there is no problem, in that he will know what is worth saving. So my problem is to ensure that he is notified in the event of my death, and I am wondering how to do this. -tony

Even the simplest Dumpster-tossing > cleanup person / relative understands a dollar sign. I think that means we all need to own Leicas to start with. How many would make me greedy? My biggest worry is that my will will not be found and/or my next of kin will not get contacted. He isn't a relative of mine, just a very close friend. He is the beneficiary of my will and the exector, but if this is not realised he might not get what he should. I am wondering if there is some way of ensuring he gets told if anything should happen to me (not that I am planning anything like that, but...) -tony

oddball (XT PC-era?) keyboard - "dejag" etc controls

by jules.richardson99＠gmail.com

Rescued a keyboard from the dump earlier which is about the same style/size as an IBM model F, only a darker grey color (and not a buckling spring mech). Layout-wise, there are no F-keys at all, but keys on the numeric keypad are labeled things such as 'pan', 'curs', 'local', 'dejag', 'vern', and then there are eight status LEDs above the keyboard area (on-line, local, interp, busy, pan, cursor, dejag, 2nd). Does this critter sound familiar to anyone? I didn't see anything at the dump that it obviously belonged with, but I may return tomorrow and double-check, and knowing what I was looking for might be helpful. Of course it's possible that whatever it hooked up to is long-gone, or even had already been hauled off from the drop-off area for processing. cheers Jules
