That's not what's gonna limit slotket price though, more the differential between slot one and 370 BXes. The limit is socket 370 board price, not really the differential. Many people will buy a slot 1 440BX board with a cheap PII 333-400 as there are plenty of those around and find out they can …

@AlexZ Many prices are ridiculous imo. Last week I spotted an AA370P for $117. What is the point of spending money on just a slotket when you can buy an entire motherboard for a tiny bit more ? Ordinary slotket is definitely not worth it. The price cap of slotkets is price of socket 370 …

I think higher slotket prices are not a major problem as long as the seller describes exactly what kind of CPUs are supported and does stability testing to ensure you will get a working hardware. There are too many unscrupulous sellers who sell untested items for high price without any warranty.

All slotkets seem to have become pricey lately - some of the most ordinary Mendocino slotkets are Ebay listed with asking prices of between 15 and 50 dollars and I would hesitate to pay even 5 for any of them. You are sitting on a goldmine with your 11 :-). The Intel list is not complete but the …

Those brand name slotkets which passed Intel's test are going to be pricey though. I have 11 slotkets in total and not a single brand name. Not all budget slotkets are listed in that document.

At 112MHz fsb it is stable. Oddly, at 100MHz it isnt. The fun I have with this stuff is just seeing if I can push it. The easiest approach would be to buy a P3 133MHz capable socket 370 board. But then I'd want to see how far that could go... Something is definitely wrong with that board then. All …

MSI MS-6119 seems to officially support only 100Mhz FSB. I would first get a system stable at that frequency before going higher. Keep in mind we are dealing with worn out components thus usually less stable than new. 10% extra speed due to OC may not be worth potential instability. I would do that …

These projects suffer from very low number of contributors. I'm surprised PCem even lasted that long.

I would sell everything and keep just PIII as it can cover all those rigs when FSB is set to 66Mhz or L1 cache is disabled. If I had free space and time I would build a late 486 rig (5x86 133Mhz).

I think that if you ask mplayer authors you may get a better answer as to what DJGPP version is supported. Perhaps some additional libraries are missing or some small tweaks are needed. Maybe you're the first one trying to compile it for DOS for many years.

It should be fine for games even from 1994, but just not the most popular ones and not running in protected mode. Games for faster computers got released more frequently and authors stopped caring about slower computers like 286-386 at that point. An excellent comparison would be Prehistorik 2 vs …

Windows 3.x could run some protected mode games with 2MB of physical RAM when 4MB was required in DOS. Unfortunately max swap file size was dependent on physical memory size.

I would recommend to clear CMOS (I assume you added battery to the board). That capacitor is also a possible culprit however I would unsolder it only after ruling out other causes. I would try to hard reset it a few times when it hangs. Is CPU voltage set correctly? I'm afraid if you want a vintage …

Right, I missed one offset. (Sorry, I don't have the board at hand to test the modifications.) There's a new version attached to the post above; hopefully, that one works. I confirm the latest version looks ok. Menu items are displayed correctly and voltage is applied as well (verified in Hwinfo). …

Exactly. One bad comment won't scuttle their business. If they are a reputable seller they will agree to a refund. Don't buy expensive old electronics. There is no guarantee it will work even if they claim it does. I always buy just very cheap stuff. 98% of it is really working. It if doesn't, I'm …

Mendocino Celerons can be clocked up to 550Mhz. I just tested 3 of them. Celeron 366 - boots at 550Mhz. Celeron 400 boots at 600Mhz. Another Celeron 400 boots at 500Mhz. All stock voltage. At 83Mhz FSB they aren't too bad either. Back in the day I switched from K6-2 to Mendocino Celerons because …

Mendocino Celeron is the best CPU for 66FSB boards as it performs quite well at 83Mhz FSB and works up to 550Mhz. PII 450 is very rare and expensive. Celeron at 100Mhz FSB is basically the same thing but can reach higher clock speeds. It also costs a small fraction of PII as nobody wants it.

BIOS support for specific PIII frequencies is often overrated. As long as at least one Coppermine model is supported the rest should work as well. I have Enpc KB21P board and in BIOS there is max 5.5 multiplier but it boots fine with faster Coppermines as the BIOS multiplier setting is ignored. Fast …
