ATI VGA Wonder XL24 with Brooktree RAMDAC. Sadly, the card does not work. I would like to find a way to make this functional, as it claims to support dual monitors.

Why did card manufacturer combine to cards on one slot card? I think this card was quite expensive in those days.

..even ATI designed such a card: ATI VGA Stereo F/X

Thanks for all the comments. Is it possible to switch of VGA with the ATI VGA Stereo F/X? What about using a second VGA? Which is going to work?

Or just using this website..

It's worth a shot. BIOS version on the XL24 is newer than the one provided here, but it may still work.

Scratch that, the dump that MikeS provided is for the 28800-5 chipset, whereas I have the 28800-6 from the the later XL's and 24's. I will just holdout until I find a proper dump.

Great, I am collecting ROM-Binaries
I already ask vlask at legacy vgamuseum if it is possible to upload special bios binaries.
He says it takes much effort to coorinate the uploads.
Any other hint how to buit a real database for old BIOS files. Vogons drivers maybe?
I think over time it might be necessary to reflash old hardware!

Bought a Roland DV-7 with the controller, very cheap, for an obvious reason: no hdd included!

May be we both wrong.
I've done some other tests in hddspeed - dos utility specially for benchmarking hhd.

14+-------------------+-------+-------+-------+---+-------+-------+--------+

Result - ide dc680 works 2-3 times faster, than dc880 scsi version.
And dc680 cache works close to ram speed (on amd dx4-100 i've got about 30 mb/s ram speed)
May be the reason in time difference between them, scsi is from 1993 and ide from 1995.
Or may be onboard cpu is bottleneck, scsi uses 80186-16mhz, while ide is 80286-16mhz.
(all test performed with modern ide and scsi disks, that can do linear transfer 10-20mb/s)

Cache speed for IDE vs SCSI
. - .

I know that I had great results with Tekram DC-300B. It even ran an hard disk drive at 25MB/s in a K6 system.

Found a socket 4 overdrive on eBay. http://www.ebay.com/itm/151736583044

I woke up 5 minutes late to rebid on it, and lost. I sure hope someone here got it. I know I will be kicking my own ass for the next few days over this.

No, you can't. For DC-300 you limited to drive and to cache by 16-bit ISA speed, that cant be faster, than about 8 MB/s.
https://en.wikipedia.org/wiki/List_of_device_ … ates#Main_buses
So if you get a 25 MB/s, that mean that you measure cache in ram.

I am pretty sure it was 25MBs. It was the fastest Windows 95 ever installed on my computer.
I tested the hard disk, IBM UltraStar 4GB, with MHDD and it worked at least 4x faster than with other controllers (AMD SCSI in Vectra).

Most IDE VLB controllers have software drivers you can load (TSR) during autoexec.bat or config.sys that enable the cards to use VLB 32-bit for hard drive I/O, I have a generic yellow VLB controller I forget who made it in my second (backup) 486 that doesn't even have caching with it, and with a 7200 rpm 10GB drive in there it gets 18-20 MB/s with the drivers loaded. Which, using VLB for hard drives, is the entire reason for using those cards compared to the normal straight-ISA ones.

But DC-300 is an isa16 only scsi controller. They can't work faster, that isa itself.

I went back and saw your photos for the post from a few days ago... they both look like VLB to me? Unless I'm missing something there?

Well.. now I look like an idiot. I thought y'all were discussing the scsi and VLB cards you posted a few days back.. those were the recent tekram stuff on here. I did think it awful weird how a VLB card would work in a K6 system.... I should of googled the part # to see it was ISA before commenting. Oh well.

Bought an Cirrus logic VG1000 with CL GD-520 chip (made by diamond Flower INC), which is the most compatible cga card.. Its going be used in my v-tech laser XT /3 8086 10mhz system..

I really like the card because of the size of the letters.. Which is a same kind v-tech used with their own cards..

Something like this.. I think it is really rare 8-bit version..

Every thing only $10 😀

Nothing tested yet, a cap of the creative graphics blaster blown away and need to be repaired.

The lanparty has bad cap and the chipset corners looks bad :'(

Hey wait a minute. I know that machine. In fact, I know who also owns that Sun and half built Beige box behind it.

You live in Vancouver, don't you? 😉

Nice haul! Honestly I think the chances of that DFI board working are pretty good, I had a 939 Asus board untested for $1 from Goodwill w/o a heatsink or fan knocked around with huge scratches on the pcb knock around in a box for a year before being tested turn out to be 100% functional 😊
