Cool topic, feipoa. First one is for industrial automation?

That second board is certainly "SMD for you and me" - a far cry from early-mid 90s 486s

I wonder if the "ESA" on the second one refers to an extended ISA bus, or to the European ESA space agency? Either way an intriguing board, with not just an ALi chipet from 2005/6, but also a BIOS datecode from 2000 and a bona fide (and standard) 3-pin CPU fan header, a PC speaker, not to mention the SMD all over the place and of course the IDE flash disk. Very surprising to see a Dallas RTC in the middle of all this modernity 😉

ESA is a brand for industrial motherboards: Electronic Solutions Associates. The point of the thread is to see how late the datecodes went with these 486 chipsets. This information could be of interest when ordering replacement chipsets, that is, you can specify a certain datecode range when ordering.

I have one of those boards with the single PCI slot. VIA with 9848 datecode

What are the model numbers of that VIA chipset?

Just noticed this is a different model to the one posted earlier in the thread. Interesting. :p This thing has a problem. Ultima 6 misses notes when an OPL3 is used. My other 486 PCI board has the same issue.

To confirm, you have a VIA VT82C496 and VT82C505 chipset with a datecode of week 48, 1998?

I'm all ears...
486 seems like to be the Jason Voorhees of the computer industry.

The VT82C496G has 9848 and 82C505 has 9705. Sorry this took so long. Got busy this week. Those the industrial 486 MOBOs were made into the early 2000s. Check around on Ebay and looks at the datecodes.

Sorry to revive such an old thread, but I figured I'd contribute this oddity.

Recently, I purchased this American Predator Corporation Predator 747. It has a Chips & Technologies F84041 chipset, and a date code of 9944.

Corvalent, which appears to be American Predatorpost-rebrand, sells this same board here. I have no clue if this listing is current, but seeing as it's meant for industrial applications, it may very well be. I wonder just how late the date codes on the chipsets they're using these days are; I can't imagine that Intel is still producing these under the Chips & Technologies name.

When I have some more time, I want to make a real post about this thing. It's pretty fast and yielded the highest scores I've ever seen on a VLB S3 864 paired with a DX4-100WB.

Wild, design of board looks more like 93 or 94 maybe.

Has now an UR page with bios/manual available:
