I went mad with a Magic eraser earlier, and brought my 3.5 and 5.25 Apple II drives in to looking as good as the main computer. I also used a friend's floppy emu to make sure the system was working beyond the self-testing.

Out of curiosity does anyone here have experience with Ark Logic Video cards >?

I've been offered a pair of them an Ark 1000PV and a Ark 2000MI, I dont know much if anything about where the Ark based cards sit in regards to DOS or what other cards perform on a similar level.

Oh noes, the cap let the shmooo out 😁

If you look them up around here they seem to be great for DOS but absolute garbage for Windows Acceleration

hmm

Garbage Windows acceleration isn't an issue if their DOS performance is solid, always nice to have a few good DOS video cards to use.

Seems the 1000PV is a great DOS card and the 2000MT is just as good, might give them both a whirl in my DOS rig.

I spent a bit of time today doing some programming on my 486DX4-100 using Borland C++ 4.5 under Windows 3.11. This would be my second ever DOS program (in C) - the previous one being something to output my current IP address as DHCP flashes by too fast during startup to easily catch the output.

This program figures out if NZ Daylight Savings Time is currently in effect - this because the DOS SNTP client I use doesn't do daylight savings time; you've got to pass in the UTC offset on the command line. And I don't want to edit my autoexec.bat twice a year. So now the right thing should just happen automatically on startup - something I'll get to test on the 3rd of April.

Lately still optimizing my netbook oriented mini-itx dual Atom SoC to work as fast as it can on Win 8.1. The GUI reduced to the lightest possible configuration and using most of its DIrectx9.0c integrated smartphone oriented SGX545 GPU to "accelerate" gui and games. Not as bad as might be expected. Testing games like Far Cry with 800x600 at medium level details is almost playable and similar would be on Doom3. Considering this iGPU basically has almost no power impact at the plug when stressed (maybe a couple of watts) it's interesting. An external video card on PCI can increase the compatibility and final speed as tested with the Geforce 210 or GT610 (on PCI only) but I wanted to keep the compact mini-itx case.
Interesting to see ATi tech demos for 9700/9800 cards running on this hw almost smooth. Generally I'd say that beside the very weak CPU it's still GPU limited monitoring the cpu usage. But as GPU-Z reports, it has 4 Unified Shaders and 2 ROPs and 4 TMUs on a 400Mhz clock and using shared 1066Mhz DDR3 memory.

Swapped out the tired stock cooler on my Slot-1 Pentium 1000 100/256 CPU with a nice new shiny thin finned one with copper heatspreader. Used Arctic MX-5 for the paste.

It seems like it is going to run just fine at 1.12Ghz in the GA-6BXC motherboard I put it in though I will most likely try one of the modded BIOSes as they are supposed to fix some stuff with the OEM BIOSes.

Also put that motherboard into an old Dell Dimension XPS case in preparation for building a system to test out PCI sound cards. It will also end up being a full build.

Don't feel lost.

There's so much you can do in Workbech.

You can enjoy the pre-emptive multitasking, by running multiple things at once, the speech reader, the bouncy ball thing, a notepad editor.
You can use WHDLoad to launch games and demos from Workbench.
You can make your own icons for things; check out the icon for launching Monkey Island for example.
And look at Workbech through the ages on YouTube up to the present day. It's done well.

I am trying to remove the HSF from a PII-350 I own so that I can mount it on a PII-400 I recently purchased. However, there is a problem: I can't seem to figure out how to remove this bolts/screws that have it tied down. Are these small allen key screws? Are they torx screws? Anyone have experience with removing and remounting these?

Check out this thread about said type of cooler.

Re: Pentium 2 SECC heat sink removal

As a side note, one of my allen keys are now permanently twisted 🤣 it's that tight they are ...

Please use the "quote" option if asking questions to what I write - it will really up the chances of me noticing 😀

Yeah, I tried oil as well as WD40 to break the rust and that inhuman grip, but it only worked on two of the screws. That thing is bolted onto there by Thor himself.

Don't do it. Just find one with SECC2 cooler.

I actually just found a Pentium II 450 which worked out even better for me; now my 1998 build has the best CPU that was available that year. (I only had a PII-300 😀 )

Great find 😀. Easily serviceable with massive Foxconn heatsink. Have 2 just like yours, Compaq branded.
You can attach regular, slow moving 80mm fan there with no problem:

Huge project weekend, couple more mobos for testing dozens of video cards for DOS. Became kind of a technical nightmare with trying to use a CF/IDE adapter, which I gave up on after about three hours. It seemed to be actively sabotaging, no matter what changes I made to the configuration, it would try to boot to CF if it was plugged in, so I couldn't reformat it or copy files. UBCD could see it but nothing worked. My Conner 1gb drive seems to have died in the process as well.

The Gateway P2 233 is kind of amazing, perfect balance of old and new features for a late non-speed-sensitive DOS machine. USB as well.

Finally used a Fujitsu drive and got the 486 running, after a lot of config headaches, though after testing a few cards I got a memory parity error and packed it in for the day.

I went to Goodwill and got a C64 modem for $2.50 though, and a few other things. They never have computers anymore, anything interesting just happens to have slipped by the sorters.

*Too* *many* *things*!

Downgraded my Cx5x86 PC from Win95C to DOS/WfWG. Feels so much more right. Also installed mTCP and now I can transfer files to/from it easily. Also played a bit of Dune II. One of the few games I know where the FM Synthesis soundtrack is far superior to the MT-32/General MIDI ones.

I don't know what the issue is exactly, but I have problems with trying to use CF cards as IDE drives if they have ever been formatted in Windows. Even Partition Magic for DOS reports and error with the partition table and won't allow any actions to be performed on it.

I am always able to fix these issues by booting to a floppy, deleting the partition using fdisk, and formatting it there. Then it will recognize properly in Partition Magic, DOS, 9x, and boot properly from the BIOS. It's also recommended to use "fdisk /mbr" to ensure that the master boot record is written properly, just to be certain. This procedure has always worked for me, even on the most stubborn of CF and SD cards.

Hehe great tip, "don't feel lost". Why didn't I think of that! 😁

Thing is, I only had an a500 and I was 7 😀

Well, this CF is brand new (though a small 256Mb) and fdisk won't detect it, though the BIOS does. Actually I tried several partition utilities, drive scanners, etc... The CF could be defective but I haven't had time to put *another* system to check it. I tried 3 adapters.

Fdisk says "invalid drive designation."

Smells like you need to use that util for changing it from removable drive.

I reflowed the memory chips on a Radeon X850XT (AGP) with my hotair station. The card was giving me issues with black squares randomly popping up on the image.

The previous owner had covered almost all of the memory chips with small heatsinks. Except two of them - why this decision was made, I don't know. Maybe he ran out of them...

Reflowed them both, put brand new thermal tape and heatsinks on them and...all the issues are gone! I'm happy I did not have to go the full reball route.

Another card saved from the trash. 🥰 This will make for a killer 98SE build. I just need a quiet and powerful fan now. My Zalman OP1 is driving me crazy at 12V and running it on 5V barely keeps this card cool.
