What was your first CPU ?

[CMBURNS]

😳 oops, it had 640K of memory not 8 meg

 

[SK711G]

286 8MHz (12MHz Turbo baby!!)
1MB ram
40M HD

the coolest thing was it could format low-density 720kb 3.5" floppys to 1.44MB High-density, but only it could read those disk, but it was way cool

 

[1Tanker]

Nice thread. 😀 😀

 

[fazers_on_stun]

Got you beat!! I went from my 8086 10Mhz all the way upto a 486 DX33 I didn't go the cheaper SX route because I wanted a Math Co-Pro so I could continue to use Autocad!!

:lol: Yeah, that would be something like 20x speed increase I guess. I used to have some utility (MIPS or some such) that would count NOPs I think to "measure" speed. As I recall, my 4.77MHz 8088 Tandy 1K posted about 370K NOPs per second, the 12 MHz 286 around 1.2M and the 486-33 around 8M. That's a whole lotta nuttin's per second 😀

A friend with an Atari ST 1040 once ran MIPS using a DOS emulator - I think he hit about 30K, which was about 3x the estimated speed of ENIAC or some such

 

[monkeymanuk]

386 SX 40 (not sure which brand)
2 MB Ram
20Meg HD LMFOA:
256K Trident Video Card (That can't be right can it?)
B&W Monitor/soon upgraded to full color
Windows on floppy disk!!!!!! 😳

Man, Doom scared the living sh!t out of me

Got it home and immediately opened it up!

First ever proper computer was Atari 800XL, I loved it.

Mapping the Atari was my favourite book.

Coded in 6502 Assembler.

Poking had a whole different meaning back then.

 

[BaldEagle]

The first computer I bought in 1981 was the ATARI 800 "Loaded" with 48K RAM and a 5.25 floppy.

 

[cal7]

if i dont count the Z80A...and some Motorola 68xxx in Amiga mine was a Cyrix P133 (got rid of it and bought a P200 MMX to play Quake )

 

[chuckshissle]

I had the Pentium. Got my first pc back in 1996, I payed on my own hard work. It was an HP as far as I can remember. It had 64Mb ram and 15Gb hard drive with 533 cpu. That was the best home pc when I bought it.

 

[cal7]

Note to the OP ...... I never saw a pentium133mmx ..... If I remember correctly the first intel cpu to have mmx were the 166.

i think you are right about that

 

[Guest]

A p166 authentic a 2 gig harddrive 32 MB of RAM and I think either 2 or 4 meg of vram with a 8x(or 4X?) CD Rom. Hard to beleive it costed $3500.

 

[powerbaselx]

Feeling all nostalgic now so now let us post, what was your first cpu/rig 😛

First cpu was a Zilog Z80 on a ZX Spectrum 48K (48KB ram) in the mid-eighties (1984 or close).

After several ZX Spectrum (mostly substituted due malfunction and _refrigerator_ abuse...), i bought a ZX Spectrum 128K (the last Spectrum which still works nowadays!).

Then i moved to my first PC in 1990, a Hyunday equipped with a 386SX-16MHz, 2MB ram and a 40MB hard drive (which all still works nowadays at my ex-girlfriend mother house, with Windows 3.11 and 8MB ram!). This has a 32-bit cpu on a 16-bit bus and no math coprocessor (the famous 387sx!) 🙂

After that...
- 486DX-50, 16MB ram
(i refused to buy a DX/2-66 because the bus only worked at 33MHz...!)
-- (in the meantime, i bought a AMD 386DX-40 -- great cpu)
- IBM/Cyrix P166+, 64MB ram -- too hot, too unstable!
- Pentium 200MHz, 128MB ram -- pretty much stable cpu
-- (at work i bought a AMD-K5 233MHz -- lots of blue screens...)
- Pentium III 550MHz, 384MB ram -- another stable cpu
- Pentium 4 3.0GHz, 1GB ram -- working at 3.60GHz most of time!

The videocards also have some history...
- 386SX-16: Trident SVGA 512KB ISA
- 486DX-50 and IBM/Cyrix: S3 805(?) 2MB VESA
- Pentium 200: ATI 3D Rage Pro 4MB PCI
- Pentium III: NVidia Riva TNT2 M64 32MB AGP 4x
- Pentium 4 (v1): NVidia GF6600GT 128MB PCI-e
- Pentium 4 (v2): NVidia GF7950GT 512MB PCI-e

[halbhh]

MOS Technology 6502 cpu in an Apple II+ with 48K ram.

Sweet machine!

Was able to squeeze a huge AI program to play Monopoly into that 48K, written in Applesoft (BASIC). Lot of fun.

More fun details: disk drives were expensive back then, so I used a cassett tape (!) to load programs for a year. (really!)

 

[Rhinofart]

It would have been 12 Mhz. My buddy was all like I have 2 Mhz more then you. Plus I have an Intel 80286 and you only have an 8086. Bastard. But who's got the systems now bizatch!!!

Oh sorry for the outburst there. LOL

 

[CompTIA_Rep]

The first computer I "owned" was a Mark I which I believe ran at 100khz (no not mhz).

Anyway, the 4kw power requirements were a bit tough back then, but now adays, thats nothing.

[danielcoles1989]

lol my first CPU was a P3 450MHz, 256MB RAM, 15GB HDD, DVD-ROM! state of the art....bout 6 years ago 🙁 oh wait it must be even longer cause i had windows 98 pretty soon after it was out

 

[kukito]

MC68000

 

[Parge]

P75! The first ever Pentium!

8mb of RAM

545mb HD!

God, i remember installing a mechwarrior demo that took up 220mb of hard disk, that is the equivalent of a 125gb demo today lol!

 

[ethel]

486 DX2/50 with 4MB RAM

Bought it for college, but was really happy to find out it played Doom very nicely

 

[Rhinofart]

You are indeed correct. Also the 166 came in both the MMX and non MMX version.

 

[Rhinofart]

LOL I had that utility too!! I would put the CPU in normal mode (4.77 Mhz), and then again at Turbo speed. 9.4 Mhz rounded up to 10 and boy did the mips go through the roof.

 

[nachogod]

The P60 and P66 predate the P75 and where actually built on a different die. It had simular pin spacing like a 486, but was bigger. I think it was the biggest CPU I've ever seen.

 

[Rhinofart]

Actually there was the Pentium 60 and Pentium 66. You don't remember the whole Pentium 60 Math calculations fiasco??

 

[4745454b]

You are indeed correct. Also the 166 came in both the MMX and non MMX version.

You guys sure about that? I remember my parents buying a P120, and I was trying to talk them out of it because the P133s with MMX were coming out like next month. My mom said "if you wait for the latest and greatest, you'd wait forever." I replied with "not forever, next month", which she didn't buy into. I'm 90% certain based on this memory that there were some P133s with mmx. I could be wrong and maybe they were delayed/pushed back. Anyone with linkage?

 

[Rhinofart]

Yes. 100% sure. I had a P-133 as well. They came out with the P-150 and P-166 and then a month or so later they had the P-166MMX which were incompatable with non MMX mobo's as the CPU had 2 different power requirements for each portion of the CPU core.

I just can't remember what the 2 different voltage requirements for the core were. 3.3 and something else though.
