it's a nice board, pity it's missing the YMF chip.

Wow, PC/104 video card, that's definitely rare.

PC104 stuff, especially useful PC104 stuff like audio or sound, is so tough to find I ended up making my own PC/104 to ISA adapter board. Nice DB50XG too 😀

I bought this TNT2 Ultra, Speedstar VLB, and a Daewoo socket 3 board from my e-waste guy.

I guess the Daewoo mobo is a CPC-2900, but I'm not finding much documentation on it.

No heatsink on the TNT2 Ultra unfortunately. Fan power header tells me that the fan is probably unique on this.

Put something like a Zalman NB 47J on it if you have enough airflow in your case.

that speedstar with the Trio64 chipset must be an awesome VLB card, kudos!

Nice. You must have paid a pretty price for that? I'm glad I never sold mine, although I've lost other hardware over the years (moving around). I have the exact same card. I think I got it in late '94 and it currently sits in my 486/100 build next to a CT1740.

My Gravis Ultrasound and 16 bit daughter board

In fact it came as a 'package deal' together with a Roland RA-50 and I paid a lot less for the bunch than the current lowest "buy now" price (edit: it's actually bidding) for a GUS on ebay (which is 125 euros starting price for a 256kb rev 2.4 version).
I am planning to have it sit next to my awe32 ct3900.

yeah, it's the first time I even found a "normal" PC/104 VGA board.

...and yes I've been listening to the DB50XG all day with the Tyrian2000 jukebox ^^ had to swap the sound card in my current 386 setup as the CT1740 was refusing to output sound through the wavetable... CT2910 was the quickest at hand without me having to change any settings and seems to work fine :3

Got 2 computers and 3 crts today.
Both computers are 486.
The desktop have dx33, Trident 9000 vga, full size AT psu, caddy CD rom and a SB 2 pro 😁
The baby AT tower have dx4-75 overdrive and CL 5428 VLB 2mb
The mainboard are damaged, anyone know what happened? There is no caps who look damaged in the area.

CRTs
Dell p992 19" trinitron (happy about this one 😁)
Hitachi CM 625 17"
Forefront vm-1400 monocrome

That corrosion you see is from a leaking bios battery. Your best bet is to cut the batteries off and give the boards a good once over with some white vinegar and a toothbrush and then a nice rinse in distilled water.

No it's not, the battery is a long way away and is a cr button type that is looking good.
I did clean it some with alcohol. But i guess i have to take it out and inspect the traces. Could those tantals leak and still look okay?
The board is a FIC 486-pvt

one of the fastest chips for dos AFAIK

Yes, pretty much the best VLB for DOS when you take into account both speed and compatibility, when matched against other "high-end" cards such as the ET4000/W32P. I dont't have an ARK1000 VLB (which is said to be the fastest) to compare, but my Trio64 VLB is a bit faster than an ARK2000 PCI when using the same 486-class CPUs.

It also has the best image quality of all my VLB cards, despite having an integrated DAC.

I've had this for three days now but only got around to actually testing it tonight...this is a most cursed PC indeed. Hardware wise it's just a Micron Pentium 66MHz desktop (albeit with a rather nice Diamond Stealth32 (Tseng ET4000) video card and a SoundBlaster 16 CT2910) but...someone along the line gave it this truly bizarre spatter paint job on almost all the plastic parts of the case. That and it has a messed up Windows 95 install with various things that are just straight up missing, like...all of Plus's desktop themes, for example. This thing is going to be a fun project.

Nice. Socket 4 or 5? Check if it has the FDIV bug. 😁

Socket 4! As for the FDIV bug, that will have to wait until after I wipe and reinstall 95 as the current install just is not usable with how...mangled it is.

Something I forgot to post earlier.
CL GD5424-80qc vlb

You can't see it, but the pcb has a metallic green sheen on it. Its a really spectacular looking card.

Got these two motherboards from a website called Alltronics (can't find the thread about them, did it get deleted/moved?)

Looks like it was deleted. Glad I saved the url 😀

Hi Debs, mind sharing the URL? PM ok? Thanks

What's the difference between these overdrive chips and regular DX2s?

The ODPR is practically identical. The ODP is meant to be installed in the overdrive socket. It has one extra pin (to avoid it being inserted incorrectly into the socket). It also has UP pin outputing low signal so that it can disable the other CPU if still present (such as when soldered on the motherboard). On standard DX2 this pin is input waiting for the signal from the overdrive CPU.
