If you get stuck you might try athana.com. They have lots of hard/floppy disks, including some alignment media. I've used them to rebuild RK05 media. A few years back I asked the owner how he stays in business. Two words: Federal Government. Marc On Wed, Apr 11, 2018 at 9:10 AM, Bill Degnan v

Re: Speed now & then

It might break the rules since it only goes back to 1999, but here's Moore's law for integer speed, floating point speed, number of processors, memory sizes and disk sizes for the machines connected to SETI@home. Plots are averages and medians, unfiltered for errors. At least one of the paramete

5.25- inch alignment disk needed

I find myself in need of a 5.25-inch alignment disk. A few years ago someone mentioned a source for those, but I can't seem to find it. Is there still a source, or does anyone have one they'd be willing to sell? I could use an 8-inch alignment disk also, but don't need that as urgently.
