On my win7 pro 64 bit systems, there was nothing to download. It is already in the OS. Use windows explorer, right click on executable, select properties, then comparability. Options go as far back as win95. The feature never really seemed to be essential. The 32 bit emulator always worked.

Yeah, it's a bit of a pain - it's basically intended for people running old XP apps that they don't want to (or can't) port to the newer versions of Windows. The other thing to watch out for is that as far as I'm aware all the hardware is emulated with a little hack to allow USB passthough - so

Hmmm. 99% of the time I just plug things in and see what happens. That's what they were designed to do. If something pops I fix it from there. If a fuse keeps blowing I use the light bulb in series trick. On older tube gear I do softly bring it up with the variable autotransformer

Hi My experience with several VM's has been unrewarding in terms of drivers. The driver lives on the main OS and may or may not pass through to the VM. You seem to get a sub-set of the main OS devices in the VM... Not a good thing for hardware hacking. Bob -Original Message- From:

If I recall, the firmware in the RFTGm collects about an hours worth of position info and does an average to establish a self-survey. The next time you cycle power, it will check the new position against the stored one and if within 50 feet or so, it will use the stored position. That's

Incandescent light bulbs are very useful. They are a high dissipation resistor with a lot of uses. I have one in series with a bathroom ceiling fan, just kept plugging smaller watt values in until the fan was quiet enough but still fully functional. I have one in series with a micro drill

Incandescent lamps also have the property of a cold resistance very much lower than that at design voltage. Used in series with drills and bathroom fans this gives a useful current surge at switch-on. And the [time-nuts] connection? I use a torch bulb in series with the drive to a dry cell

There is one angle that was not covered, but which is relevant (at least to those of us using any LF or HF time receivers). Over the weekend I bought my first LED bulb. It was on sale and I wanted to see how it worked. On the package it gave a warning that it could interfere with HF

Sorry Tom, (again!), Just as significant is the radiation from compact fluorescent lamps, many radiate strongly in the 50-60KHz region from their SMPSs. This has been the reason for failure of several clocks I am aware of that are tuned to radiocode transmissions on 60KHz. John H. On 12 Oct

Another connection from Time Nuts to incandescent light bulbs is the early HP Wien bridge oscillators. They used the light bulb for amplitude stabilization. This light bulb stabilized oscillator is what put the HP company on the map. There was a time when these oscillators where the best
