The thing is that it has long been known that the black tarnish
that forms on silver is silver sulfide. I have noticed that most
of the unwashed masses think that anything that corrodes, or discolors
a metal is a rust, or oxide... even when it isn't.
Silver oxide is not formed easily. It

It just so happen I have a never used USB-printer port adapter (with the

Dear Joe,
Be aware, the parallel printer ports are not a substitute for the LPT port!
My experience is that only two things work:
1. A PCI card in your PC to add a LPT port (cost around 15 Euro)
2. Homebrew LPT ports. If my memory serves me well there was a design in
the June or July/August

As mentioned the real answer is no unfortunately. I used to use raw printer
bits for all kinds of stuff. Not anymore.

I have looked into this at length without success. It appears that the
parallel port was orphaned in the USB definition and an emulation can
only support printers. Scanners, software key dongles and other
parallel port devices are not and apparently cannot be supported. An

Those should be real ports. They probably connect through the PCI buss
as a PCMCIA card would.
For those looking to PCMCIA/Card Bus, be careful. There ARE cheap cards
that connect through USB rather than PCI. The true PCI cards DO work.

Hi
There are Atom based motherboards that still have true parallel ports on
them. They come out to a DB-25, but are otherwise just like the old ones.

Yes it exists, and does exactly what you want:
your applications see a 'real' LPT port that you
can write/read at low level like it was a real hardware port.
It has a DB25 connector on the end.
I have two of them, they work great.
I tried old prom programmers and lots of small PLL loaders etc
My solution was similar. I have a few old systems that work fine and
have serial and parallel ports. For my more recent workstations, I
add a PCI or PCIe serial/parallel port adapter if needed.

It's single shot resolution would still be from the interpolator, even
if you measure on the same signal.

No problem, and it's much better anyway to hear from someone who's used

A couple of years ago I bought an Intel Atom Dual Core board. It's

Hi
I think the answer to the Atom puzzle is that the standard Southbridge chip has
an LPT port in it. More or less they get it for the price of the connector or
