AST

Release Date: 1/1/1993
Manufacturer: AST
 
Donated By: Don Archi
 
AST Research started out as a computer board manufacturer and became a Fortune 500 company in 1991. It just goes to show how powerful companies can become with computers and how quickly and hard they can also fall. This machine is nothing remarkable although it still works well and has been upgraded to include 16MB of memory which is more than enough to run Windows 3.1. This machine is the first in an upcoming series to not only showcase the computer but also the operating system that is running on it as future computers tend to be all based on similar hardware technologies.

This machine is also capabale of using both 5.25" and 3.5" disks.

I had a Commodore 64 before it, but the 486sx25 was the computer of my high school years. Upgraded it to 12mb of RAM, and added a new hard drive (120 MB, maybe?). Also got a CD drive/sound card for Christmas one year. Getting that to work was a mission. I remember having bootable floppies for every game I owned. It played quite a few that it didn't meet the minimum requirements for, too. Man, I kind of miss those days.

Also my first. It kicked my TI 994a with 8 bit memory expansion box's... Don't remember when I got it, but at the same time bought a shareware version of DOOM. Those were the days, bought the full version on line, took 4 days to download at 9400 baud rate. My AST was a 486 sx 25, meaning it had no math co-processor. So it did crash a lot.

Got my AST Advantage 486sx33 desktop in June 1994. Used it for a couple years and built a new system. I still have that PC stored. Not sure the shape its in now. It was a real beast and able to play anything for its day even when it should not have been able to. Love it.

This was my first PC in 1994. Before that I was a Commodore user only. Don't have this PC anymore but still run my Commodore.

My first computer. I have the 1994 version of it and it was bought in Late 1999 when I was a toddler. My Dad (probably) upgraded my computer to a Pentium processor and Windows 95 OSR2 during that time. This is the computer that I mostly played Tonka Construction during my whole childhood life! Great Memories!

I have an AST Computer - UP8810A V10 V3.6 I bought myself Dec. 1996. I turned it on when it started to boot up, I got a message that the system battery is dead. Where do I get the battery and what is the battery No. I cannot find it in the computer information I got with the computer. I would like to get one.

Yeah, I remember this, this was my 1st computer, I bought a doubler chip for it, so it would go 40mhz. It was awesome! Ran 3.1 and played tons of Kings Quest, Quest for Glory, and Aces over... what ever flying games on it.

This was my 2nd computer. (my first being a C64) I have fond memories of this machine. My parents bought it for me when I was 12 years old. I played a LOT of games on it. My favorites being Chuck Yeager's Advanced Flight Trainer 2, Wolfenstein 3D, and Microsoft Flight Simulator 5.1. Fun times.

This was my first computer as well. A lot of games I recall at that time required EMS/XMS which happened to have a lot of editing of the autoexec.bat and such. One of the best experiences came from Wolfenstein 3d. I think the biggest limitation of it was the memory and the fact that less than a few years after getting the computer, bigger games and applications required more memory and better processors. The computer stopped working post Y2K and I never bothered fixing it unless you set the clock to like 1991 or so. That was the biggest fault here. Not sure if they even had a bios update or not and never bothered looking for one. Sadly had to throw this thing away a long time ago.

my first computer, learned a lot on it. upgraded with "multimedia kit" cd rom and sound card, added another 4mb of ram so i could play doom without a boot disk :) always wished i had of got the dx33. have been looking for one to put modern motherboard/cpu in.. wonder if they have all been recycled.

This was my first serious computer back in a time when it cost real money. I remember paying about $500 for just a SB16 and a Creative CD drive (not burner). I gave it away a few years ago and it was still running perfectly.

Good all-around computer for its day but it sure had its quirks! 25 MHz CPU, 4 Mb RAM, 170 Mb HDD (if I remember correctly). Came standard on our machine with a 5.25" and 3.5" floppy disk drives (displayed in the picture - no CD-ROM though). At one point I tried to install a CD-ROM drive (24x!) and attached the IDE cable to the secondary port on the motherboard. Turned on the computer and the cable promptly melted! Eventually daisy-chained the HDD to the CD-ROM, which worked fine. Oh, the memories!
