Does anyone here know someone or someplace I could obtain a socket 4 motherboard and/or a Pentium 1 66mhz processor? These two pieces have alluded me for quite some time. How rare are these parts of this era these days? They rarely show up on EBay and other sites. Any help or leads would be appreciated. Thanks!
Apparently they're rare enough that I see Socket 4 Overdrives more than I've seen Socket 4 motherboards.
Unless this is something that you SPECIFICALLY NEED, you probably are better off getting a Socket 5 or Socket 3 system. PODs for the 486 are about as fast CPU and FPU wise, and if you go for a AMD 5x86 with really nice cooling and a stiff overclock, then you can go even faster than a Socket 4.
Well I'm not really looking into speed. Ive started a project where I'm trying to make a seperate build that each has whichever the fastest pentium of the year was throughout the 90s. I have every single processor and motherboard I need except that combination.
Here are 3 places you can get the Pentium 1 66Mhz CPU from.
Not cheap, but it is available.

And here is a really expensive socket 4 motherboard:

A bit of info to help you with your search:

I too would like to know where to procure an inexpensive socket 4 motherboard so that I can add the results to the 686 benchmarks. I almost had a decent one for $30, but it slipped away. If you are looking for just the socket 4 P66 CPU, CPUShack on the CPUWorld forum had a few extra as of about 8 weeks ago. They usually sell in the $20-$30 range.
A socket 4 with Pentium overdrive would make for a very expensive system. I think they run at 125 MHz, but I may get corrected.

The Socket 4 overdrive CPUs run at either 120 or 133Mhz depending on whether you replaced a 60 or a 66Mhz Pentium.
Here is another Socket 4 motherboard with the Pentium 60Mhz (without FDIV bug)

And some more part number info for the 66Mhz Pentium

If you want a Socket4 system, you are WAY more likely to find them in OEM PCs like Dell, Micron, AST, Gateway 2000 etc.
I disagree that socket4 overdrives are more common than the boards. I think a lot of the auctions just don't properly list what is being sold. Socket4 boards can easily be mistaken for 486 boards.

Whelp, you convinced me to buy a POPD5V overdrive for socket 4. Now I just need a socket 4 board to test it.
Weren't many socket 4 boards notoriously slow and buggy? If so, finding top quality boards may prove challenging.

The most common Socket 4 boards were in Packard Bell Legend 300cd machines. They used just a large heatsink and a fan attacked to the case blowing over it (which eventually stopped spinning and the machine died).
I have one of those machines and a Gateway2000 model with a P66 in it.
No way to mistake a socket 4 (very large CPU) for a 486 board. A fast 486/133 or 160 would run circles around the P60/P66 but I never bothered to upgrade the CPU I like then as is.

You're forgetting that Socket3 has an extra row of pins only used by the Pentium overdrive. Socket3 is just slightly smaller than socket4.
If the CPU is inserted, then I agree that it would stand out. However, if the board is being sold bare it's really not obvious at all.
The Intel based boards are easier to spot since the Mercury chipset has 4 chips, but not so much with SiS, OPTi, UMC, Forex etc.
For somebody familiar with Socket4, it's easier to spot them, but to the untrained eye they don't look like anything special.

The most common socket 4 board that anyone is going to spot is going to be the Batman board and it will usually be the oem version from Gateway with ps2 ports. Got two working boards ready to go and still haven't built a rig around them yet.
On a far away planet reading your posts in the year 10,191.
The Batman and Batman Revenge / Hendrix boards are ok - not the fastest but not as slow as the OPTi Premium boards (which are cool nontheless, there are VLB and PCI / VLB boards available from various brands).
The best boards, without a doubt are SiS based. Abit and ECS made decent ones.
My absolute favourite is the ECS SI5PI AIO: http://www.amoretro.de/2012/03/si5pi-aio-rev- … otherboard.html
I have this board with a 66MHz CPU and 1MB of cache. Lovely board.

Thanks for all the good info guys! From what I've gathered getting these boards and especially with a 66 pentium may just be better left to chance unless your wallet is thick. I will just keep my eye out in the wild unless a good deal comes along otherwise.
There's just something I really like about the idea of having 1MB cache on a classic Pentium.

Little bit on the exotic side but seems high quality(IBM server). You might have to ask the seller if he has all components to get the thing running unless you're familiar with that specific setup.

Here in The Netherlands it seemed s4 is about as rare as s5 and Slot A (it was all Slot 1 over here) and s423 is a bit more common compared to s4 and Slot A.
The only ones I ever seen are the already mentioned Batman Intel boards. The funny thing is that both s4 boards I found were from AT systems badged as Commodore. These boards do not have the PS/2 plugs iirc. One of my boards seemed to have some sort of damage though and I can't remember if I ever got around to test the other board (possibly I did test it at one time though).
s4 had a very short production run, but that Batman board was still produced in not too rare numbers I think, it's mostly the age that makes them harder to find.
I do not have any of the s4 POD chips and all but one of my s4 Pentiums for sure do not have that FDIV bug.
When not carefully looking, it's easy to miss that one s4 board amongst all those s3 and s5/s7 boards out there, so I can understand it being easy to miss for someone who isn't paying attention to the socket detail all the time.
