It is well known that PCChips is a shady company and that they've faked many things in their history.
For example, in the pentium era they rebranded chipsets with many strange aliases that are documented here :
https://www.hardwaresecrets.com/chipset-alias … -vx-pro-and-co/
For the 486 era they often used UMC chipsets which they erased an added stickers ontop of them.
But I noticed something ...
There is nothing about the 386 era boards they've made !
Take the M396F.
here's mine
Sometimes they come with a sticker above the chipset just like with 486 era boards.
Sometimes they come with a different alias
And of course the M396F isn't the only board impacted by this. Take this M326 :
As you can see they sometimes have a "Sarc" chipset ... But what is "sarc" ? They're only seen on pcchips boards it seems. I highly suspect "SARC" to be yet another pcchips owned brand which doesn't really exist and was used to rename chipsets.
When you compare the M326's chipset with this one, they look quite similar !
But I don't own this boards, neither I own most 386 era pcchips boards. I need your help to properly identify these chipsets which are very likely to be well known chipsets with just a different name written on them.
IDENTIFIED CHIPSETS
- SARC RC4018A4 + SARC RC4019A4 -> UMC UM82C491 + UMC UM 82C493F
- PCChips M321's chipset : Opti 82C391 (proof here Chipset datasheet for M321 (PC Chips) [Found chipset! OPTi 82C391])
