I guess I'm not the only person who also collect vintage computer and Intel microprocessor as well

I still have the original IBM PC

I also have a few IBM PS/2 (Model 60, 70, 80, 56, 77, 90 and 95) in my collection as well.

I have some old clone computers as well.

I have posted a few CPU's pictures at www.cpu-world.com as well.

Oh wow Robert, you've got an amazing collection! The PS/2 model 95 is on my bucket list of vintage computers to get.

I like vintage microprocessors as well, namely Pentium and older. I have an AMD Am486DX-40, an AMD Am5x86-133, an IBM-branded Cyrix Cx5x86-100 with the blue heat sink, and a Cyrix 6x86-120.

And you never had to heat your Alaska home ever again.  (At 130W TDP, the Pentium D is among the hottest-running x86 processors ever.)

The thing had a pretty impressive heat sink on it, and a noisy fan, but it did the job.  Worst was a laptop my mom had, which used a Pentium 4.  3 screaming fans and the computer would slow down as it heated up and the CPU throttled down to try to control temperature.

Not all of them were 130W. Few were 95W same as P4 Prescotts (the Pentium D is 2 Prescott cores together, but the P4 had Hyper Threading, in the D each of the cores had Hyper Threading disabled, so that helped keep the power relatively down)

The cooling is not a biggie, any decent sized massive cooler can handle them (noise is another question though)

The big problem is the mainboard VRM's

Many mainboards - nearly all the "cheap" ones, but even better known companies like MSI and ASUS - They make a board that does support the Pentium D on BIOS/software/clocks level, and state that the board supports a Pentium D. A year later the user finds out that the VRMs in that board were never built to handle 95W, let alone 130W... a hit of "that electronics smell" and the baord is to never power up again. Closer inspection shows darkened areas from heat around the VRM mosfets, and sometimes a hole in one of them

Unless a board really appears to have solidly built VRM (in the hardware of that days, physical sizes and amount of components do represent capability fair enough), dont put a Pentium D in there. In some boards i'd avoid even a Pentium 4..

And there is the 4 pin 12V connector. The pins in that thing are rated officially at ~8A/pin, so that 4 pin plug (2 pins / pole) would, in theory, support 192W CPU, right ? Nop. I dont see how those pins can handle more than 4A..5A without the plastic melting around them... I would not use 130W CPU in a board without 8 pin connector

Neat glad I am not the one who likes older computers

With CPU sockets and the LGA just because it fits does not mean it will work

The first LGA 775 sockets were specifically for the Celeron and Pentium IV of that time frame and would not boot with a Core 2 (Duo/Quad/Pentium Dual Core) not to be confused with the Netburst based Pentium D) based CPU


Is any one on this site into the art of Hackintoshing? Ex: running OSX on a Intel PC Core 2 based or newer Core i series

This particular P4 was a 95 watt Presler.  The fan was throttled by the motherboard, but was fairly loud at full speed.

When evaluating what a 775 bord can handle, if nothing else, look at the RAM slots. Most Core capable boards are DDR2, most non capable are DDR1. There are exceptions though

What i was about is, you connect it and it will work, but overload and eventually burn the board VRMs

Worst was a laptop my mom had, which used a Pentium 4.  3 screaming fans and the computer would slow down as it heated up and the CPU throttled down to try to control temperature.

Yeah, Pentium 4 laptops were the worst. The earlier ones, up to about 2.6 GHz, were manageable, with a TDP of 25 to 35W, but the later ones were up to an unreasonable 88W. The Pentium M which replaced it was a godsend.

my first laptop was a Dell inspiron 5160 with a Pentium 4 at 3.2ghz that was the 88w TDP unit.  it was a better heater than a computer (yes I kept the heatsink clean).  you could cook on the bottom under the heat sink area.  fan running on high constantly.  this model was known to ruin the USB controller inside because it was right next to the heatsink.  worst computer ive ever used.  tore it to pieces when the power jack broke loose from the board and junked it because it wasn't worth fixing.  I use mostly desktops now but I still have a newer (2013) dell notebook if I need to be portable.

When my 6 year old K62-366 based laptop was finally done, it got replaced with a Pentium M based laptop.  Thing was like an ultrabook compared to my mom's P4 laptop.  Ran cool and quiet too.

That was my dream computer I wanted to get when they first came out.  Boy, they were very expensive such about USD $10,000 a pop back in 1990s.

I have fair amount of 90s hardware - Mostly Pentium and Pentium MMX Socket 7 based hardware (full sets sufficient to build more than a few PCs), and a fair share of Pentium II/III hardware too. I even got 3 dual Pentium III servers + 1 more dual Pentium III server board

Found this in the station today. 8-inch floppy disk. Date of 1983 printed on the label.

Neat I knew they (8" floppy disks) existed but I have never seen one in use before
Can you do a compairsion of a 5.25" and a 3.5" disk (If you can get one if not don't worry)

I've seen only 5.25" and 3.5" floppy disks. Bad sectors were most common in this type of media, compared to other types of storage media.
