What is the one best test to perform to throughly test the performance of the Motherboard and not just the CPU ?
Is ther one test that can test
Motherboard
CPU
RAM
Cache
Bus speed
Etc....

I guess a all made in USA 486 is not possible, all those Taiwanese chips inside 😁

Well, according to the “Buy America act”
To be labeled “Made in USA” a product needs to have at least %50 parts made in USA.
These computers are also assembled in USA.

So while you can’t have a totally “Made in USA” 486 computer they are close.
Only the floppy drive I can not find Made in USA.
Everything else you can.

So I am testing computer that have the “Made in USA” label printed on them.

What I am testing is mainly the motherboard setup.
CPU, RAM, Cache, Video, Bus speed, etc.

I am looking for just 1 test that can test all these features and provide 1 combined score.

Nobody here gives a rat fat about the "Made in USA" Act

There's a glitch in the matrix.

What “Made in USA” components would you guys like to see put into this Ultimate Made in USA build ?
You can choose from the motherboards and cards I have posted.

Hey guys,

I have another “Made in USA” VLB socket-3 486 motherboard.

What Made in USA CPU do you suggest or I could go German with and AMD CPU ?

66 or 100mhz.

I think it supports 100mhz CPUs

I think I've found your motherboard's documentation : http://www.win3x.org/uh19/motherboard/show/5487
Could you please take a clearer shot so I can add it to the page and also make a BIOS dump using this http://cd.textfiles.com/microhaus/mhblackbox3 … MORY/GETROM.ZIP ?

According to the documentation your motherboard offcially supports a 66MHz chip at most.

There are two versions of that board 4GPV3 and 4GPV3.1 afaik. 4GPV3 uses SIS 82c206 and 4GPV3.1 uses HMC 82c206 (or is on my 4GLX3 [4GPV3.1]
Re: 80486 BIOS image collection

added: found this update to jumper settings while searching for info in December, never found the full manual.
Was tagged for the Atrend Galaxy 3 [4GPV3]... You may find it useful.

Not change the BIOS but save the BIOS to a file 😀

Merged the "USA machine" posts over to this topic, seemed a bit cleaner that way. Thanks folks for the head's up!

I guess the WINNERS are going to be the ones that are durable enough to still be working.
Currently the VLB motherboards are in the lead with best performance.
So I will have to benchmark these 3 with the same ram and CPU to get a WINNER.

Candidates
1) Mecer/Galaxy/Atrend - German Contaq chipset motherboard
2) Young Micro - Symphony chipset motherboard
3) Mylex - with Opti chipset motherboard.

I want to run just one benchmark test to test the performance of the motherboard.
What is the best one test to run ?
Topbench ?
Speedsys ?
Dsrystone ?
Other ?

Pick one for goodness sake. Wouldn't take long to test those three anyway.

I am going to take into consideration more than just performance.

Things I am going to consider:
1) Specs
2) Max capacity limits
3) versatility of bios config
4) Ease of config in bios
5) CPU - performance and bottle necks
6) Motherboard - BUS speed and customization, slots, battery, jumpers, quality.
7) Cache - capacity , Speed, and customization.
8) RAM - speed, capacity, banks, and preformance
9) Graphics - speed, megabytes, and customization
10) Hard drive - capacity limit, speed, and performance, Quietness.
11) PSU - Watts, and Quietness
12) Case - design, customization, and ease of repair
13) Drives - Default drives that shipped with computer.

I am going to make an excel spreadsheet to rate everything “1 thru 10”.

Currently the “IBM PS/1 Consultant computer” ( model #2155 ) with 486dx2-33 is blowing away the competition.
As for a prebuilt in 1993 it has the best motherboard with bios support for up to 64mb ram and at least a 710mb hard drive.
A nice compact low profile metal case with Non-IBM proprietary parts for easy repair and upgrade path.
It can support an “Intel overdrive 486dx4-100” or “AMD 5x86-133 PowerStacker CPU”.
The Bios even supports the “IBM 486dx2-66 Blue Lighting CPU” ( Cyrix ).
The Multimedia edition came with a Sound Blaster 16 or Pro 2.0 with Panasonic 2x CDROM drive which still work today.
Unlike the Sony 2x CDROM drives which were plagued with bad capacitors the Panasonic drives are still working today.
Its fairly quiet and fast for a 486 computer. Bios boots quickly.
But most importantly what really sets these IBM PS/1 computers apart from the rest is the software and recovery features and menu systems.
This computer was loaded with software and menu systems for ease of use and recovery.
It has batch files for many types of recovery and restore options to keep your computer running like new.
This is what set IBM computers apart from everyone else.
The menu system and batch files are very helpful and made this computer as easy to use as a Mac.
Also this computer has energy savings modes, sleep, and hibernation.
Not common in a 486 computer.
The onboard video was not bad with the Cirrus Logic 5428 graphic chip.
1mb. of video DRAM and Support for 256kb. Of motherboard cache.
In 1993/94 this was a solid performing 486 computer.
