What's even more interesting, it survived the jump to electronic media quite well.
Up till recent versions one was in each copy of Microsoft Word, too...
No. In reality, you are pretty much ALWAYS using internal caching in the machine. Internal RAM on the MB is much faster an larger than anything the disk can do.
And, with long linear reads HD's head becomes bottleneck, so everything else has to wait for and having cache on disk or not becomes mooot point...
AFAIK Win NT's almost whole purpose is for network applications, and here Unix rules anyway...
Wine and FreeDOS are getting better by the day for API emulation for DOS/WIndows applications, so why is it so important to have this ?
O.K. There are some heavy weight applications that require Win2K or better, but those things are so expensive that a few extra bucks for OS shouldn't kill anyone...
Actually, you need field of certain strength to cancel residual magnetism. And after holding the ship with magnets so strong, the "degauser" would have to generate considerable field.
But all this seems moot, becuse degausing could be done with holding electromagnets themselves moment after releasing the ship. Just after release they would have to aply decaying, alternating filed-like degausing coil in your monitor...
Not quite true.
Based on the experience with similar problems inside familiar electronics (analog modems, inkjets), there is much room for improvement here.
One could use phase modulation (various time between droplets) in many forms and maybe even droplet size modulation.
I guess it could be made to look quite effective with bit rates around 50 bits/sec or even more...
You are underclocking your Z-80. It should be good up to at least 2.5 MHz, workong within specs.
Z-80B should go up to 6 MHz and z-80H should be fine up to 8 MHZ, without overclocking. So Moore's law can't touch you for at least four years;o)
Slashdot Mirror
power is inversely proportional to distance^3
Khm... Isn't that really distance^2 ?

So now they only have to outlaw using mirror finish on the shells...
