I did see that and for people that need that specific functionality it seemed like a good solution. My goal was more "What if DOS hadn't ended and but kept up support for modern hardware" along with emulation of common things

Correct, there is a difference between MS-DOS and IBM-PC compatible and a DOS (ex: all the DOSes that existed for Amiga/Apple II/Commodore etc). There are many DOSes (and even MSDOSes, because yay early PC era incompatibilities!),

It's a complicated space. There are attacks on both maintained and unmaintained stacks. There are definitely attacks against windows 95/98 too because people have things like mills or other industrial automation that are powered b

You attack the networking stacks for it, those are still actively developed (mTCP was last updated Jan 2025) as businesses use networked DOS for quite a few things. A DOS networking stack consists of a packet driver, a NIC driver, and a pro

So Epictronics recently looked at the 386SX, the version with the 16bit external bus, which was slower than the 286 at the same clock. What changed between that and this? Was the major difference the double clock hit on fetch? Or did it hav

Not just that. Most operating systems lie about when an IO transaction completes for performance reasons. So if you lose power or the IO device dies you still think it succeeded. A mainframe doesn't do that... it also multiplexes the I

I'm apparently off by a factor of ten, but then again I'm including the fuse... which probably does cost the other 18k. I've updated my post to include that to make the distinction.

IMHO: Yes, subs are great when you need people to constantly be looking over their shoulder and spending tons of money on ASW. They are great at interdicting logistical shipping too. But, they are really really bad at being seen (that'

Yeah I realized that was the worst way to go about testing that anyway right after I went to bed last night. If (big stress on if) that was the issue a ferrite bead would be a better way to test it. Based on what you're saying my SWAGs

I'm curious, if there are any high level electrical engineers reading this please respond. I wonder if that vertical (as far as the PCB goes) power connector will always ensure that this sort of imbalance will always occur. While we li

Honestly with 50A of current we should be using connectors that screw into place firmly and have a single wipe or a single solid conductor pin style. Multi-pin connectors will always inherently have issues with imbalance of power delivery.

I think a lot of very accurate reasons have been covered by others. These are my key points: * COL in most areas has skyrocketed, housing and healthcare have both ballooned in cost massively. This has meant I'm much less likely to take

At least where I am, I would attribute it to code requirements. A livable attic requires much more work to meet code than a vented attic space. Not to mention the energy cost of having a livable attic can be higher because there is no venti

Sucker's bet. They almost certainly do. The question is more would the homeowners have actually been better off if the homes were more damaged requiring being rebuilt? Based on anecdotes from the Hawaii fires... the answer is: Maybe. C
