Some enormous laptop that ran DOS 2x...

Apple //c

A Seequa Chameleon i got from a neighbor of mine.

• Has both a 8088 and a Zilog z80, making it able to run both MS-DOS and CP/M.
• 128kb RAM.
• Two floppy drives.
• Can't seem to get it to boot up anymore -- perhaps there's a cap leaking or the Bubble Memory carts have failed...

As a funfact, i helped SmartAlex61 on youtube identify a certain mystery computer that turned out to be a Cham with no case.

IBM PC/XT 5160 with PC-DOS 2.1

I remember using an OLD Dec terminal at a friends place, but the exact model alludes me.

The oldest one I ever used that I can name is a TI-99/4A from 1979.
Surprisingly, it has a 16-bit CPU!

The oldest computer I bought new was a Pentium 2 350
The oldest computer I now own is a 486

Acer Extensa 367t.
My dad has a IBM PS/2 Model 60 laying around.
But he won't let me plug it in. Probably because it is huge and surrounded by all of our "spare" monitors.
And to give you a hint how many monitors? I have three spares. One from my early childhood.
Multiply that a few times.

Some old [censored] computer with Windows 95. I remember it couldn't play Charlie II without a lot of lag.

I believe it was on old Pentium 1 with Win95 installed on it. It was old, broken down and slow, but I really miss that computer

Well, some what old thread and old news, but I used an IBM 140x setup, consisting of an IBM 1401 processor, IBM 1402 Punch Card Sorter, IBM 1403 high speed printer (and I mean faster than the high end laser printers I've seen) and a IBM 1406, although nothing was done with the 1406. Also had 2 IBM 729 tape "decks" that were just running test sequence. Also originally punched the punch cards with a terminal that I can't remember the model number of, I want to say IBM 29 but not 100% sure.

*TRUE STORY* Back in school (Around 2005) everyone would fight over the "New" Windows XP Machine they had, it was a HP Pavillion multimedia PC with a 30GB and 512MB Ram. However there was another machine that ran Windows 98SE, had a 8GB Hard drive and 128MB of RAM, it was fully loaded with Office 97.. eventually the school got a second HP Pavillion so the fighting stopped. However I still used the trusty Windows 98SE machine. In 2010 when I finished primary school my old teacher that I had in 2005 said that "the school were going to get rid of this, but I want you to keep it as a reminder of your old school" And to this very day, I still have the HP Pavilion, still running Windows 98 SE and still has all of my saved schoolwork on the hard drive!

Update: Used on a VM ms dos 3.

You really need to try out a real DOS system, VMs just don't cut it for me . A Pentium or later is best.

I've never tried a real DOS system, but once I saw a computer with Windows 95 (which runs off DOS) but the mouse driver was broken so I couden't use it...

But the keyboard still worked, right? You could just press F8 on Starting Windows 95 message and select Command prompt only...

Title: "Oldest computer you have used???"

MS-DOS... "MS-DOS [...] is an operating system for x86-based personal computers." ~Wikipedia

MS-DOS is not a computer. It is an operating system.

Kids these days... *sigh*

Hi, I am dedicated for over 15 years to fix PCs no matter how old they are. I get more satisfaction back to life a pre Pentium PC, the older the better I feel, because it is like watching history live and interact with it.

In these years the oldest I've ever used and repaired are the IBM PC-XT. I have also used Commodore 64, TI-99 Texas, etc.

I once used some kind of Amstrad.. but didn't have the OS disks..

Ok, in that case probably oldest (that I can remember) computer I have ever used is a old Compaq laptop.

Well, my oldest computer had Windows 98 installed on it... Sadly I don't remembr the brand.

When I was 4 I used a Median PC
I remember the specs xD
256mb ram
40gb Hard Drive
1.6ghz Intel Pentium(forgot the rest)

The oldest computer I OWN is a 2007/2006 MacBook Pro with Mac OS X 10.5.8. (it came with with 10.5.4) Still use it, in fact I'm typing this on it!

It has a 2.4 Ghz (yes, you read that right) Intel Core 2 Duo CPU, 2 GB 667 Mhz DDR2 SDRAM, and a 298GB HDD. (I don't know what GPU)

320 GB, not 298.
The graphics can be either Nvidia GeForce 9xxxM or Intel something.
