      Think of it this way.   Remember "wash boards"?   I don't know if you
have a different term for them in Sweden, but they are how we washed
clothes a century ago, before automated washing machines.   It's a rough
metal plate in a wooden frame that sticks out of a bucket of soapy
water, and you rub the clothes on it to flush out the dirt.   If the wash
board is patented, and someone still owns that patent, it's very
unlikely that anyone in the business world would consider that patent to
be worth anything, for the obvious reason.

Analogies are always problematic.

Consider this - a piece of software used in embedded applications is a
piece of software you will probably never hear of. Might not even be
possible to buy if you tried.

    Well yes, I understand that.   I am an embedded systems developer.   But
see below.

Does that mean it is dead, or have no value?

This is the state of TOPS-20 at the moment. It is being used as embedded
software, that you'll never see, or hear of. But it's still alive.

    I'm aware of the use of the XKL chipset's application in the network
switches, but I was unaware of their use of TOPS-20.   I thought they
were running a bare-metal firmware load written for that purpose.   Is
this not the case, are they actually running TOPS-20, or at least some
part(s) of it, on those embedded processors?

    If so, I need to pull a few strings and get my hands on one.   Or several.

Yes, they are running TOPS-20. But exactly how much of it, I can't tell. I'm no expert on TOPS-20, and mostly go on what I can recall Rich Alderson telling me.
