Intel i486 DX2

I was not aware there was Intel 486 Dual Core CPU. »en.wikipedia.org/wiki/In ··· 80486DX2 I have always thought that Dual Core CPU did not come out till late 2000's.

I wasn't aware that it was dual core either, because it isn't.

I had one in my first PC back in '92 or so....I remember cracking it open years later and finding that it was an AMD clone. Local computer stores could be pretty shady back then but there wasn't really anywhere else to turn (that I knew of anyways).

I had an Intel 486 DX2 66 based system as my first computer as well. It was purchased at a local shop as well but after that I went to Dell for my second and third systems. After that I started building my own.

When I bought the first system I was concerned so I made sure I got exactly what I paid for.

It had a turbo button on the case which toggled between 33Hz and 66Hz. I always kept it at 66 or at least I did for the most part.

The guy I bought from after that first store was this sketchy old dude who would show up at your house with the parts and do your build/upgrade.

Sketchy part was that he would take cash, offered to load up the computer with pirated software and porn (even though I was like 14) and asked for a beer (my dad loved that one). Apparently the business was under his wife's name because he'd already been busted for tax evasion. But damned if they weren't the cheapest computer parts in town.

After that I learned places like Canada Computers had shipping so I started building my own.

My first PC I built had a 386DX/40 AMD CPU with 4meg ram and a mono SoundBlaster card and a 1200baud modem that I used to connect to Compuserve. I think it also had a 512k video card.

DX2 doesn't mean dual core. It means clock doubled. It had a clock multiplier that ran a "standard" 486 clocked at, say, 33 MHz at 66 MHz instead. There was still only one CPU core.

I bought a 486 DX2/66 with 16 MB of RAM in 1993 that was my primary gaming box for some time. Doom, Wolfenstein, Duke Nukem 3D and that ilk all ran great on it. Quake spelled its end.

If I remember correctly, the "2" in the "DX2" stood for "clock doubled". I think the 486DX2's were the first processors that ran at a multiple faster than the system bus speed.

My first machine that was close to the state-of-the-art at the time was a 33 MHz 486DX. I got it back in early 1992 to get me through college since my 8088 XT clone wasn't quite cutting it. I had to take out a loan to pay for that 486DX box .

I remember the DX2's had just come out a few months after I got my 486DX.

Nowadays, processors run (or can run) at several times the system bus speed, as many an overclocker can attest to .

I had a DX4 100 MHz. No it wasn't quad core lol but thanks for the funny post i486 processors were SX or DX. DX had a math coprocessor while SX did not. The number after referred to the maximum multiplier speed. The good old days....

You guys all make me feel old.
My third computer was an 8088 XT at 4.77 mhz.
I later moved to a 286 at a whopping 20mhz!!

Technically my first computer was a Commodore 64 bought with money from my paper route (boy am I old), then a Commodore 128. I went with Commodore for gaming, 64,000 colors and three sound voices beat the tar out the the IBM offerings of 8 colors and a beeping speaker.

I got into IBM compatible PCs in the 90s and build a 486SX25 as part of a correspondence course that was covered by my GI Bill. The SX stood for S*CKS. My first bought IBM compatible PC was bought from a local shop with the parts I selected and was a 486DX66. I've been moving up and onward from there with a combination of bought and self built machines. I build about every five years with a video card update or two along the way.

I am about to make everyone look like kids. Granted, I did not get this computer right when it came out, but this one was my first »en.wikipedia.org/wiki/TR ··· Computer I upgraded to an Apple II from that.

I had a dx4 120 that had a clock crystal on its board from a pentium mmx 13. The starting mhz was higher than the 486s. So while it should have started at 33 mhz it started at 66mhz. I was able to take the dx4 120 up to 198mhz. I did kick it down to a bit slower though with a 2.5 multi for 165mhz so for a few short months i had the fastest pc out there in raw mhz obviously not in over all performance. But it was allot of fun to see peoples reaction to the 486dx4 @ 165mhz and 64xxxx for ram on post heh.

Buhahah i had one i also had the tsr80 color computer 2 and tsr 100 portable :0

As for 486 any thing i think i had the most fun building tweaking and just fooling around with those old comps. They could have so many things done to them that you just can not do today.

In reply to inssomniak

As for 20mhz it was such a huge leap in speed from the previously top of the line that it would be akin to moving from a 86 20mhz to a p3 500mhz or athlon clasic 700. It was a major leap in tech.

hmmm, if you think about it. With the 386 you could also buy a separate math coprocessor. The 486DX came with a built in math coprocessor, so I guess it was kinda sorta like dual core....

For me it was a Sinclair Spectrum with a whopping 48k RAM! Those were the days, ah man!!!!

As for PC, a 286/10 with 1 MB of RAM and a 20 MB ST225 HD.

Ah, a stroll memory lane (bad pun intended)!

My first pc was a 386sx/20 from NEC. I think it had 2MB RAM?

What I do remember was using QEMM-386 which had far superior (true) multitasking to anything Windows could offer at the time.

EDIT: Oops, forgot to include mention of DESQview, also from Quarterdeck. That was the multitasking environment when used with QEMM.

Ah... the Intel 486SX CPU or sometimes referred to as the 486Sux or 486Sucks. It was missing the math co-processor so it couldn't do floating point operations. You could install a math co-processor on your motherboard but it essentially replaced the main 486 chip for most operations.

Amazingly those could address up to 4GB of RAM. I think mine had 32, possibly 64MB of RAM toward the end of it's life.

Sure is. 4GB of RAM back in the 90's would run anything under the sun.

And 64MB cost a pretty penny back then. Sticks were not that big either. While the CPU could theoretically address 4GB, chances are neither your mobo or wallet could handle it.

I used to have a Cyrix 486 DX2/80. Good times. It was my second or third machine.. depending on if you count the C64, which didn't actually belong to me.

My 286 could be toggled between three speeds: slow, slower, and oh god why? But I still rocked me some Gunship and F-15 Strike Eagle on it.

The slow modes where necessary for some old games that where locked to the CPU speed, like the old DOS Megaman game, the faster the CPU was the faster the game played, a 286sx at 16Mhz would be normal speed, 25Mhz was fast and 33Mhz and beyond was ludicrously fast to the point of instadeath from enemies you can't even see coming.

What was commonly done, if you could afford the RAM, was to use the extra as a RAM drive. You'd boot the machine and copy your data from the hard drive to the RAM drive and get blazing fast performance.
