We had a version that was both DOS and Win95. It had a very cool joystick (with a hat) included. We think it was $100 at the time. We also loved the original Warcraft game. WC2 was pretty good, too. 2021-10-27, 20:56 #24 RetroGamer Oct 2021 Houston, TX 3×5 Posts Quote:  Originally Posted by ixfd64 DOSBox works pretty well in my experience. Yes - DOSBox is excellent!

What happens if the computer discovers a new prime number? Is that even possible? Also, what happens if the CPU is actually failing? Prime95 stops with an error? BSOD? Windows reboots? I confess, I’ve just run the thing like an ignoramous without really knowing what it’s doing (aside from math problems to find prime numbers).  2021-10-28, 01:53 #26 Uncwilly 6809 > 6502 """"""""""""""""""" Aug 2003 101×103 Posts 1012410 Posts "Torture tests" don't test numbers for primality. But, if you did find a new prime your machine should beep like the old ^G sound. 2 days is nowhere near enough time test a single number. Old machines would have to run months to test one of our double checks. If Prime95 finds problems it will say so on the screen. If the machine fails bad enough, it may BSOD from heat. 2021-10-29, 06:29 #27 henryzz Just call me Henry "David" Sep 2007 Cambridge (GMT/BST) 5,939 Posts Quote:  Originally Posted by RetroGamer Yes - DOSBox is excellent!

Have you tried running any of these on Linux? Wine can sometimes run old windows programs better than windows itself. 2021-10-31, 06:16 #28 RetroGamer Oct 2021 Houston, TX 3·5 Posts Quote:  Originally Posted by Uncwilly "Torture tests" don't test numbers for primality.

Thanks for the quick reply and info. If torture tests don’t test numbers for primarily, what is the CPU doing when we run a torture test? After all this time using the torture tests, I have to admit, I don’t know. 2021-10-31, 06:20 #29 RetroGamer Oct 2021 Houston, TX 3×5 Posts Quote:  Originally Posted by henryzz Have you tried running any of these on Linux?

What would wine do, run an emulated version of Win98 or can one install and run an old 3dfx game directly somehow? Just wondering too - the old desktop I’m using - I doubt that would run anything but a 20 year old version of Linux. So - you’re talking about Linux on a modern machine with glide wrappers and such, right? 2021-10-31, 07:00 #30 RetroGamer Oct 2021 Houston, TX 3×5 Posts Quote:  Originally Posted by Xyzzy We had a version that was both DOS and Win95.

Yes, that’s what I’m talking about! The days when a comparatively complex game (compared to todays FPS games) was sold in stores bundled with a joystick with a hat switch!!!!

Or a copy of a game included with a high-end graphics card that’s specifically written to work with that card.

I really do miss the late ‘90s. That’s why I want to keep a few of those classic desktops around and running well. That’s also why I want to use Prime95 - to make sure they’re healthy.

It is going through the motions, but it is not getting any assignments from the server (if you are using the "torture test" option from the menu.) It do all the things and run through all the different FFT sizes to test the machine without doing productive work. Yes, it will work on a number(s). But, that number(s) IIRC is already is known not to be prime.

Yes Linux on a modern machine. Wine emulates a Windows environment for progrmas on Linux. While they do update it for modern programs it runs old programs very well as that is when it was developed. You might also try win 98 on modern hardware or under a virtual machine.

Win98 will not profit much by modern hardware : a lot of the functions of the CPU, the PCI slots will not be supported. Even some storage devices will not be recognised. You will not find drivers for the GPU, the network, audio, ...
Taking Windows 7 as example, it does not support AVX512, NVMe drives need special manipulations during install to be used as boot disk... This will impact virtual machines as well.
I suppose that part of the fun is keeping that old hardware and OS running :-)
