Add another $675 for a 25mhz 128k cache 486 motherboard, OPTI chipset, AMI BIOS, 16Meg on board, two 8 bit slots, 5 16 bit slots, I calculate $1125, plus tax. The system scores 41 on Norton SI. Runs 25000 dhrystones on my benchmark using MSC 5.1. Same benchmark on a Sun 4/330 (16 mip SPARC) gets 23000. The 486 is probably faster because the who dhrystone benchmark fits in the cache. Where do you get prices like this? At the Los Angeles Area Computer Swap meets. All parts are new and warranteed. You do have to be brave to lay down $700 to one guy, and $450 to another, and take two pieces home to plug them together. Bring cash or check, cause they don't take American Express, and they don't take VISA either for these kinds of prices. It does pay to shop around.

What is the risk of buying an old version? $450 is too low for any Intel part, a 387 alone can cost more than that.

If memory serves me correctly, the B5 (that the original poster bought) has some rather serious NPX bugs (Numeric Processor eXtention) that only show up running under UNIX. Therefore, it is safe to run the B5 for DOS but not otherwise. These bugs were fixed in the B6. The errata dated 05/02/90 lists bugs in the C0 step. So, B6 has long been gone. The ICE-486 on my desk is based on a C0, or C1 -- as component ID information is 402. So, no the B6 isn't the current version of the 486. C0 has been out for around 6 months. -- "Worship the Lord your God, and serve him only." Mat. 4:10 Robert Collins UUCP: ...!sun!altos86!rcollins HOME: (408) 225-8002 WORK: (408) 432-6200 x4356

I haven't seen too many 486s quoting SI, but I thought a 25mhz 486 would score about 80. They normally score 110-120 on Landmark and a 33Mhz 386 scores about 55 on this. The 33Mhz 386 scores about 45 or so on SI. -Tom

If there anyone there think, thay can get a 486-25 motherboard fore $1100 thay think wrong. (A 486-25 motherboard cost about 2200-2500 US$ in Taiwan). So if Kaleb Keithley can deliver 486-25 board to 1100 US$, ok, I think I know about 100 person that will like to ordre on!!!

Always nice to hear from someone who knows better what I did than I do. I paid US$675 for a 128K cache 486 motherboard, OPTI chip set, AMI bios 2 8-bit slots, 5 16-bit slots, *NO* cpu. I paid US$450 for a B5 486. Yes, I know that there are B6 and C0 revs available. I'll let you add up the prices, but if you can't, it's US$1125. I'm not in the business, I'm not interested in being in the business, so I'm not offering to deliver anything, at any price. Well, maybe if you want to offer $1500 cash, up front, I could probably be tempted to go buy some more and ship them to you. However, you can go to the same place I did, and do the same thing I did. Here in Southern California they have Computer Swap Meets, basically an open air marketplace where different vendors congregate to sell their merchandise. The one I went to, on the CSU Northridge Campus is *right* next to the LAPD Devonshire Division Police Station, and is patrolled by State University Police. All vendors are legit, they must have business licenses posted, they write receipts on printed invoices, they have printed business cards that have their business addresses. All merchandise is warranteed. While some stuff might be "hot", I believe the probability of the stuff I bought being stolen is very, very low. I post the prices I paid, as any good capitalist should, to provide feedback to the marketplace. Would you pay Compaq, Dell, or anyone else for that matter, $5000 to $10000 when you could build it yourself for $2000? >Norton Si 5.0 fore 486 motherboard >486-25 about 54 >486-33 about 72 Really, whose 486 is that on. The numbers I quoted were "out of the box." I haven't begun to tweak the various chipset parameters yet to see if I could squeeze higher numbers out. Anyone got the Landmark test that's willing to uuencode it and mail it to me, or point me to an archive that's got it? I'm already pleased that my dhrystone benchmark gets 26000 dhrystones out of my 486, which is a lot better than the 23000 dhrystones that the same benchmark gets on my Sun 4/330 at work. -- Kaleb Keithley Jet Propulsion Labs kaleb@thyme.jpl.nasa.gov causing trouble again.
