this 486 motherboard has ISA, VLB, and PCI slots!
(also a Dallas RTC module which probably has a dead battery)

@tubetime Awesome find! Would love one of these. Loaded with Cache and everything. ❤️

the old battery is now disconnected.

@tubetime You are trying to connect a new battery to it? Nice 🙂

@tubetime Looks like somebody was poking around already?

@drscriptt not really, it should be pretty well sealed

@tubetime good to know.

Thank you.

I’m now less worried about similar systems that I have.

@tubetime I'm still kinda weirded out that this is a 486. I keep thinking this is a SPARCstation 10 and typing out forth commands to redo the checksum in my mind.

Because seriously a 486 shipped with an SGS/Thomson TimeKeeper? This is the most expensive 486 motherboard.

@tubetime seems like the kind of thing you would find build instructions on hackaday for. Nice work

@tubetime My god it's the millennium falcon!

@tubetime that unpopulated space on the motherboard with a circle that says «batt», what’s that for?

@oven alternative way to assemble the board using an RTC chip that has no built in battery. the chip footprint is under the socket where you can't see it. the external battery socket goes on the footprint you noticed.

@tubetime The first computer my family owned was a 486 DX2 66 MHz. Man we got a lot of use out of that.

I think dead batteries are normally the ones that don't shock. /s

@tubetime I believe I had this board back in 1996. We used to refer to boards like these as VIP-motherboards, short for Vesa/ISA/PCI.
