 Posted: Fri Jan 18, 2008 10:36 am Post subject: MOBO and stuff for ST 486 |
 |
|
I want to build a PC based on my ST 486DX2-66 CPU. What MOBO with all the necessary stuff like graphics card etc. will support it? How much will it cost?
I really want to see a 486 in action  never seen it before
Thx in advance |

It should be supported by just about any 486 MoBo.
Until you know what MoBo you have, nobody can fully advise on what add-on cards. It's necessary to know whether you need VLB, PCI or ISA (all boards will have ISA, but the could also have VLB, PCI or both).
I can sell you a working 486 board. I'll have to dig it out, and it will cost 5 EUR plus shipping (and be tested and working before leaving me).
Please PM if you are interested and want details.

Most 486 motherboards will work. You will have to set the jumpers to the right speed. These jumpers are usually located near the cpu or near the simm sockets.
You'll need some ram, depends on the motherboad, but most likely 30pin simms. Some support the 72 pin simms.
Power supply,
Heatsink fan for the cpu. Pretty much anythign will do. Some double sided sticky thermal tape should hold a small heatsink well if you cant find one ot fit the mobo.
Graphics: any AGP ( if the motherboard has it) or PCI ( again, if the motherboard has it). Last resort is an ISA type.
Floppy drive
Maybe a small hard disk. (40MB HD's were about standard around 1991) Older motherboard BIOS's cant handle large drives of today. A HDD to CF memory might be useful if it will work.
You'll need a boot floppy, you can make on in WinXP. That will get you to a basic DOS prompt. From there youc an run CPUID programs or even Win95/98/ME should run, but you will need a HD for that and time to get it all working.
You can play older DOS games, some of them are better than you might think, but other than that the novelty of running an old system might wear off. It's hard to imagine the days of command prompt only computing if you never experienced it I guess. But you are not missing out on much, I spent countless hours trying to get drivers to install, setting up config.sys and autoexec.bat files, assigning IRQ's etc.. |

Around 1992 I remember going from a 486 sx33 to a DX 33 to use with POVRAY ( drawing program) The speed difference was amazing.
To use the program you would specify the shapes you wanted where, the colours, textures, light sources etc all in a command file. Then the CPU would render the image. It used to take many hours to render a single simple image on a SX, but a fraction of that time on a full power 486.
edit: its still there..

AGP? Was that around in the days of the 486? I thought that it was difficult even to get PCI back then, which is why most of the boards will be either ISA or ISA/VLB. Naturally, I agree that whatever bus type it has, using something other than ISA will always be the best option for speed and functionality
One thing I will add to that - if you have to buy an ISA card, try to get a 16-bit ISA card, not an 8-bit one

oops.. I meant VLB. I have a couple Cirrus Logic ones in VLB somewhere. |

Well, when I found my 486, I took out the MOBO but left the expansion cards. I doubt it works cuz I didn't take it out with care, but who knows? And I still got some RAM from the MOBO.
Now I regret I didn't take the whole compy, cuz for me, it's a rare find...

What type of PSU do I need? I guess the MoBo is AT or something like that. I can post a picture if you want

If the power connector has 12 connections in a straight line, it is an AT board. If it has a block of 10 * 2 connections, it is ATX.
