Today I ordered a Dallas clock chip replacement for use on a socket 7 board I have with a dead rtc battery.

Where did you source it from?

Some new HW that came in recently:
1. Radeon 9500 Pro and non-Pro moddable to 9700:

2. Pair of GeForce4 MX460s:

3. Pair of 1GHz slot-1 Coppermines and PIII-S 1.4:

Sold my one only a couple of months ago and regretted it a lot.

Was extremely excited to have an offer of £20 accepted on this one 😀

Nice find , but man that font really reminds me of that silly you wouldn't steal a car anti piracy commercial 😆

:edit damn that actually looks like an exact match
...or maybe not they look eerily similar though.

Likely from eBay, which there are sellers that sells "newer" Dallas RTC batteries. These still works on Socket 7 motherboards that uses the RTC chip.

Most would rather get the Glitch Works RTC replacement module instead so they could use a coin battery and making replacement easy in the long term.

Wow, that is quite a deal!

Just some seller on ebay.

I like that it has a replaceable battery.

Most would rather mod original Dallas chip retaining original motherboard look, as well choosing the most economical and ecological solution. 🤷

Well, the mod is quite the same thing for me in terms of functionality. 😜

I also tend to prefer the original look whenever possible as years ago I bought one of these Dallas RTC to replace a STMicroelectronics one that was DS12887-compatible and the RTC was socketed in my case, so I didn't have to worry about soldering.

I also prefer to mod the original Dallas, but in some instances a low profile replacement is very useful, especially when the motherboard manufacturer puts the RTC in very inconvenient locations where it ends up blocking longer expansion cards.

I learnt this the hard way, by having to order and mod a new module.

Just bought this neat baby AT system from a local seller with whom I've done business in the past for $50.

Pentium MMX 233MHz
Asus P5A-B
S3 Trio 3D 8MB

I had no real intention of doing an AT based project, however, it could be a fun challenge to restore and upgrade this computer. The first thing I'll have to look at is replacing the old PSU with a modern ATX one (the P5A-B fortunately has an ATX power connector).

Great price and solid looking system. (Just boards tend to go north of 100.)
Depending on the mbo revision, it could be upgradeable to K6-2+/3+.

Found this ASRock K8Upgrade-VM800 socket 754 board in a PC about to be stripped at the recycler and grabbed it, seemed a pity to let it get shredded.

Wow, I had to look that up to jog my memory, but according to their website that odd backward-AGP slot is for a card that would house a Socket 939 CPU...?

https://www.asrock.com/mb/VIA/K8Upgrade-VM800/index.asp

I remember those boards being a super weird item back in the day. The idea now seems completely absurd. Both of those sockets were SO short-lived... it's hard to imagine the quirks and complications of that setup being at worth it to keep on that particular platform. I mean, both 754 and 939 together were only relevant from late 2003 to mid 2005 (except for the FX60 which was January 2006), with AM2 being a substantial improvement and adding DDR2 support by mid 2006.

Anyway, that's an awesome find. If you ever wanted to confuse a PC enthusiast who wasn't around back in those days, this board would certainly do it.

EDIT: OH! I just realized that they actually made an AM2 card for that slot later on!
https://www.techpowerup.com/9287/asrock-futur … ort-am2-upgrade
So, even though the website simply says "Socket 939", it can be used for other things, including adding DDR2 support. Wow! Probably almost zero chance of ever finding one of those expansion boards sadly.

Very neat find indeed. 😀

There is also the 939Dual-SATA2 that can use this CPU addon board.
And it also features AGP and PCEe
But there is no "magic" in supporting both sockets, as there are **TONS** of jumper to move in order to support the addon board.
Basically, it disconnects the old CPU and route all the lines to the addon board

Edit : on the k8upgrade, you can see the jumpers just left of the chipset. (black jumpers blocks)

My deep dive to retro digital rabbit hole continues - bought few accessories for my 2000-ish PC setup.
That Topping DAC sports ESS sabre chip. I was positively surprised to see that ESS™ Technologies is still in business and going strong.

Nice find mate, just one silly comment make sure that if you install a modern ATX psu, it will be mounted upside down in these AT cases and the fan will point up to the chassis.

A good solution is to use a psu with the fan in the back (older psu) or mount a SFX psu with an adapter so you can correct its position 😀

Most modern ATX PSUs will let you install them upside down, not sure how well the screw holes will line up but you only need two to hold the PSU in place 😉

Bought this AGP card cheap from a local seller. I liked the way it looked. When I came home, I tested it and when VGA bios first booted up, it showed that it is a Diamon Viper V770. It seems like a good card.
