Are you this old? 486DX2-80 processor

in #blog • yesterday

The photo shows a Texas Instruments 486DX2-80 processor resting on a square of pink foam. Its black surface bears the Texas Instruments logo, a 3.45 V marking, and a small “Microsoft Windows Compatible” badge with the classic four-colour Windows flag.

The 486DX2-80 ran at 80 MHz internally, doubling the speed of its 40 MHz external bus. The Windows badge and “For OEM Use Only” marking give the chip a distinctly 1990s PC look.

Now that is a genuine hit of mid-90s PC nostalgia! The classic clock-doubled 486DX2-80 was an absolute workhorse back in the day especially those Texas Instruments clones running on that 40 MHz bus. Seeing that iconic pink anti-static foam alongside the classic four-color "Microsoft Windows Compatible" badge takes you right back to the golden era of socket 3 upgrades, manually setting motherboard jumpers, and editing CONFIG.SYS just to free up conventional memory for DOS games.

Thanks for sharing this retro tech gem it's awesome to see classic hardware like this still so well preserved!

This is my 486 DX-33 — and I have other processors too (a small collection).
I used to dream so much about having my own PC, at least a 386, because a 486 cost even more... such nostalgia...

That brings back so many memories! The 486 era was truly a magical time for PC gaming and technology.

Thanks for sharing!

En mi experiencia esos 486DX2-80 eran el salto que todos queríamos dar, aunque el badge de Windows y ese "For OEM Use Only" en la foto me devuelven directo a las máquinas armadas a mano. Lo que aprendí es que ese bus externo de 40 MHz con el doble interno fue el primer paso de la carrera por los MHz. ¿Todavía lo tenés guardado o es solo la foto?

Ese 486DX2-80 con el badge de Windows compatible es una reliquia total, me acuerdo del detalle del bus a 40 MHz con el multiplicador x2. La diferencia se nota cuando pensás que hoy un smartwatch tiene más potencia que esa máquina entera.

El 3.45 V y el badge de Windows en el DX2-80 lo delatan como una pieza de OEM pura de los 90. Esa placa es soporte histórico de la era pre-Pentium, cuando el bus a 40 MHz era el cuello de botella real. ¿La conservás funcional o es solo reliquia de colección?

Our first computer was a 486 DX4 that ran at 133Mhz I believe. Had about a 420mb hard drive and ran Windows 3.1 and eventually we upgraded to Windows 95. Yeah I have been into computers for a long time. Technically before that we had an Apple IIe but that was already older hardware when we got that.

that windows compatible badge on the chip brings back memories of massive beige towers under the desk
