Itanium's problem is that there are simply very few people out there interested in them, not anything intrinsic in their performance or compatibility.

Also, generally Itanics, like many highend stuff, goes almost directly to the scrap factory via e-recycle contracts and stuff. As you already know, in many countries is illegal to get anything from these centers. Nekochan guys have been able to save some of that stuff with some luck, contacts and black magic, but even they can't save all it.

I think there're nowdays even more shades of "rare" definitions considering even most common ones are "rare" too. For example cpu like the Athlon 1000 on Slot is not that easy to find or the K62+@570 and the K63+@550 actually I've never seen these and I doubt I'll ever see them. Only found a K63-400@2,4v and a K62+@550 that already are not that common in the middle of most K6-2@400 or 450Mhz.
I found a 486 Overdrive DX4 100Mhz with write-through cache in a computer fair years ago. It's still nice to have with the heatsink and the voltage regulator already on the top of the cpu even if using it without a fan on it is almost scary.. heatsink temperatures goes up incredibly high.

I just saw a K6-III+ 550 on Ebay sell for $460.00! I wonder if the buyer will actually put it in a motherboard and fire it up?

We tried a group buy for 50 of them on CPU-World. A member saw it and outbid us, then set up a new eBay account to sell them. I advise against buying off that seller until lack of interest pushes the price down.

Why|? Your lose, his gain. That's how biding works.

Does anyone have a datasheet for 8086/87 before intel started using the -1,-2, -3 naming scheme?
Many years ago I owned an IBM branded 8087-6. It outperformed the 8087-3 at the same clock speed in both synthetic and real world tests (both were tested in IBM 5160 at 4.77MHz). I could never find a datasheet that mentioned the -6.

From what I can tell anything
Intel 808X-6 is very old made before 1982 and 6mhz

If you can let me know what age the piece of equipment was the 8087-6/8088-6 came out of?

My 5150 with an 8088-6 is a very early 64k model

The 8086-6 I received from the legendary Jack Allen computers bought for pennies soldered to a piece of s100 board scrap. At the time he would let me scrounge through the scrapped boards, got a real ibm ega card from there.

I was a kid at the time and when the 1980 dated board didn’t sell on eBay for $5, I scrapped it again in 1999. I never figured an 8086-6 was of any historical significance, just a failed attempt by Intel to sell a faster speed grade than the 4/5 MHz chips they otherwise were hocking.

In terms of an IBM Branded 808X being faster it doesn’t surprise me, IBM had the rights to Intels designs through the 286 and likely overbuilt them in typical IBM fashion

Ah well

I am pretty sure I bought my 8087-6 from a computer surplus in the 90s. I asked the shop owner if they had any 8087s, and they pulled out a tray with a bunch of loose chips rattling around. As it had IBM stamped onto it, it's probably pretty safe to assume they pulled it from one of the many 5150s or 5160s on their shelves. I recall, they had quite a few 64k 5150s, because they had the two screw covers and black power supplies (I had to really dig to find a 640k XT).

According to CPU-World, IBM did not make 8087s for Intel. They just stamped 'IBM' into the Intel chips and sold them in their kits.

i have a Ceramic Pentium MMX 233Mhz, brown like the non MMX Pentium, is it rare? is the only 233 i seen like this

Could be fake.

Definitely fake. Genuine MMX 233 are plastic/fibre. All genuine Q140 are the same as the retail chips.

yep, its fake, look at the voltage too, 3.2 instead of 2.8

and the SL27X its an 166 MMX

It's still cool though, because it's an unlocked 166MMX.

And will overheat due to the layer of paint, if that is not cleaned off. Might not even be a 166, the sSpec and part number don't match, so it may not even be an MMX (unless it has been tested as one)

OMG! I think my fake drinking ID in the 1980's might have been better quality than that chip.

The surface has several chipped spots that's overlaid over original surface and remarked. Fake.

I have one was 120MHz but remarked for 133MHz, fake.

Cheers,

I have a nexgen P133-D/J now. That's pretty rare. still looking for the silk screened 110 & 120 though, only 2 I still need. I'd pay good money for them, but I think a 120 popped up on ebay like one time in the past like 10 years, but all the pins were bent on it. I've gotten no leads since then. I found one collector but they wouldn't part with it. Who would right?

I have P120 but doesn't boot 😒

What was purpose of these cpus (120/133)? NxVL has jumpers for max P110?

I think only the PCI version of Alaris Nexgen mobo supports P120. I can test it for you 😀

Right, I solved various doubts about VLB/PCI cpus compatibility...

I have this one. The smaller lower writing on the top is laser etch on. Not painted.

I have a ceramic 166MMX also, no glamour shot as it's larded up with white thermal paste still. Think they were common as a 166 though.

I've got gizillions of the later 166s and 200s. They swarm like wasps...

I ran across an IDT Winchip C6 240Mhz and it is on the way now. The 200 and 225Mhz seem not that rare, but I hadn't run across the 240 before ,and from what I could find, very few were supposed to have ever been sold.

I've had one for a few years, pretty sure I've seen a few on CPU-World. They're definitely not common though
