Exactly what it says on the tin, guys. I'm curious to see what sort of ancient hardware everybody's used in their time. I myself have used (at work) a terminal from the 60s that ran on tape memory. See the shot below:



Best part? It's a touchscreen. I didn't know touchscreens were that old. Or maybe they jerry-rigged a newer screen to work with the old hardware. Who knows? It's been there longer than anyone who WORKS at my job, so none of them have any idea. Anyway, you get the point. Share away!

Wow the oldest i've used was a Packard Bell Multimedia D135

How old is that?

The oldest system I know I've used is my good old IBM PS/2 Model 25, manufactured in March 1988.

my first computer ws a 16 megahetz 386 sx, 4 megabytes of system ram, 512 bytes of video ram,120 megabyte harddrive, running windows 3.10.

I used to have an old Maxar 286 with 4KB? RAM, a 40MB Western Digital hard drive and 3 1/2 and 5 1/4 inch floppy drives running MenuMatic 6.0 on top of MS-DOS 4.01. I still have the manuals somewhere.

MenuMatic? Never even heard of that. Was it a GUI program? Also, wow. I think the first PC I ever used was some off-brand tower with 8 MB of RAM, a 120 MB hard drive, running Windows 3.10. It was so old it didn't even have a phone jack. All I could do on it was play Math Blaster. Then my mother went and bought the worst possible combo: A cheap Dell tower with Windows ME on it.

Yeah, MenuMatic was a GUI (albeit a very primitive one). I may still have a copy of it on some floppies somewhere... Also, that 286 had a modem in it. 300 baud maybe?

I did still have those floppies!
I did a quick install in a DOS vm I had lying around.

Hard to say, it might have been the 8086 computer I once used for like 2 mins at a yard sale.

IDK! i don't know what year but IIRC i think from '94 so about 17 years old

IBM Model 80 and Model 60.
We still have the Model 60.

PC: DOS PC (Maybe 486, don't remember exactly).
Alike-PC: ZX Spectrum+ PC

Edit: Corrected Post Structure

The Oldest PC I have used is an AT&T (NCR) Globalyst 200S. Ran Windows 3.1 and I was able to get Windows 95 on it but not so successfully. So I put Windows 3.1 back on it. It has 4 MB of RAM and a 250 MB harddrive. Not sure aboout other specs though...

My grandfather's pc, 486DX @ 66Mhz, I think 8Mb RAM (but there were other modules so maybe it was only 4 and I put another 4 in it), 500MB hdd, Windows 3.11 for workgroups

I just realized that MOST of the computers at my job are from the 60s and 70s, not just the one I showed above. The most advanced ones are running MS-DOS 6.0 or Windows 3.10 with a custom GUI. Kinda scary given the massive machines these things run.

Massive machines? Stuff like CNC milling or other automated jobs? If that's the case, I can understand why such old computers are still in use... Upgrading to modern hardware means that your old software will not work, and upgrading to newer hardware/software will run into the hundreds of thousands of dollars.

Actually, high-pressure industrial plastic molding. But yeah, it WOULD be expensive. I love that even the maintenance guys think some of the old ones should be replaced, though. I imagine it's nigh-impossible to get, say, DOS apps to run on a newer Windows version without an emulator, and setting up a hardware/emulator interface would be...umm...well, a pain in the a**. So yeah, I know why they don't do it. It's just kind of funny to me.

The oldest machine was a damaged looking PET 2001B from trash.
Oldest working PCs were a PS/2 75 a 286 laptop a Siemens PC-D2 running win 1.03 and GEM on dos 3.x all from 1988.
Oldest console a Darth Vader 2600.
Oldest handheld a Casio PB 100,sold it recently.
Oldest smartphone Nokia communicator 9210i from 2003.

486 at a friend.

Does my ZX Spectrum 48k count?

Pretty sure it does, yeah.

I went into an old Hebel plant that was automated by a bunch of proprietary software running on Windows 98, all the systems were networked via serial communications and some kind of specially-built hardware. I'm sure it would have cost enormous amounts of money to replace all of it.

I was so young when I was around computers I probably couldn't even tell you the oldest I've used. I remember EGA being around. I remember having old Wang computers that only had 5.25" floppies and 5.25" HDDs. Even a few that didn't have onboard IDE, serial mice, DIN keyboards, etc. Nothing any older than that.

It WAS Wang! I thought that was the brand on the old one my mom had, but I couldn't remember for sure.

oldest one i have ever used is my mac plus, 1987 model upgraded with whopping 4mb of ram and a 250mb ext HDD, runs 7.5 atm, has run 6 & 4 in the past.

Wish my Mac Plus worked, I loved it until the display board went out in it I mean them. I've got 2 of them and both have bad display boards to the point where the one just has a high pitched squeel and the other just has the click if it turning on but nothing else. Those happen to be the oldest computers I own.
