Sometimes it's the drive that starts the process of eroding the disk. I've polished and buffed the heads in one of my drives with automotive wax and retensioned the spring for less head pressure when working with really old disks or rare disks that aren't likely to survive a 2nd read pass.

Unfortunately I see several traces that need complete repair. As many as 7 or 8. Probably find more under the parts.

What chips might be good for exploring VGA and earlier, like the Hercules monochrome and CGA modes? I heard the WD90C30 is good for this. Anything else?

Does anyone have or know where to get the original installation videos for these types of upgrades? Not that I need them or anything. Nostalgia, you know..

I bought two of these recently from gfsi and they seem to work. I gave one of them a more thorough test by playing some games and stuff. The other one I just POST-tested. I really wish I had known about these back in the day. But I had my head buried in anything and everything "pentium" at that …

Defragging a compressed volume was a two step process. You had to defrag the host drive to make sure the compressed volume was contiguous. Then you had to defrag within the compressed volume to make sure it was internally contiguous too, and in order. Only then did head movement decrease and access …

I was comparing the blue disk icon in Doom against my real hardware. A mid-range 386 and 486DX2. I rarely see it in DOSBox, but see it frequently and longer on real hardware. There's also startup status I want to see.

Well I tried a few copy and xcopy replacement commands. Also tried a few small command-line backup tools. I don't recall the exact names, but they were generic freeware. I don't recall exactly what I tried, but they weren't full suites. Zipping with PKzip, LHA, LZH, ARJ, ARC, work to some extent in …

I'm looking for a file manager or utility/tool that I can use to move bulk and single files and folders from one drive to another. But it has to work in MS-DOS 5 or 6 and also preserve the time and date stamps. I tried a good number of copy tools and no luck. Ideas and suggestions are welcome.

Anyone ever use DoubleSpace or DriveSpace back in the day? Back then they were near godsends. Realtime disk compression seemed to work well and provided tangible benefits. Both then and now I was impressed with how transparent it all was despite the amount of convoluted shenanigans that went on " …

Is there any way to slow down the speed of data transfers from disk-to-memory in DOSBox? Got a few games and things that blast through their startup screens instantly and would like to slow disk access down to vintage speeds.

Who is the seller? And exactly what CPU does this refer to? The PNY PowerStacker? I bought one and did a quick POST, it worked, I used the default switch settings.
