That is a really nice 486 😀

I have one of my 486 systems in the minitower version of that case. That one is more or less untouched since 1995 when it got a multimedia upgrade.

Thanks!! Is it Tangent branded? Im sure allot of companies used this case though 🤣

PS, Mods, I just realized I posted this in the wrong forum. Should really be in system specs, feel free to move, thanks!

It's always nice to see another Super EISA in action.
I used to have my Super EISA in a slightly older version of that case. The main difference was the control panel, which had industrial style buttons and a very nice green power switch with a light bulb inside. I wonder if they changed anything else. The one I had was very heavy and made of good quality steel.

The DS1488 contains some RAM that stores EISA CFG settings. The DS1287 won't work. As far as I know you can mod it to take a coin cell battery like the DS1287 though.
The 1MB cache helps a little, but it's still a pretty quick board with only 256k.
If you really want to see this sytem fly, pop in an am5x86 on a voltage regular and overclock to 160.

I like the HDD. When it dies you can use it to anchor your yacht.

isnt 4MB/s slow for VLB?

Almost 5MB/sec, but yeah that seems off.
On the other hand, speedsys is not at all a reliable measure of anything really.

While I agree its not the best measurement of graphics performance, it usually shows >10MB/s for VLB graphics. 4 is suspiciously slow.
FinalJenemba can you run VIDSPEED? hmm maybe 805 is that slow after all https://retronn.de/imports/hwgal/hw_graphics_ … _VLB_front.html

Sure I can run VIDSPEED. But it's true that most 805 VLB cards are not known for being fast. I didn't get it for its speed. I got it for its DOS compatibility and standard VGA performance. I also have a Orchid Weitek 9000 that I could have used that has MUCH faster gui acceleration and windows performance. But its legacy VGA performance is absolutely awful, and it had lots of bugs and issues in games. The S3 is over twice as fast in VGA DOS games and has no bugs, I expect its windows performance to be much worse but I don't plan on running windows much if it all on this build.

I generally agree. But there are definitely times when Speedsys is totally wrong. For example, it reports 486DLC-40 as 13MHz. And I think we're all aware of the crazy CPU score inflation when the FPU is absent.
For the record, with ARK1000 I get about 26,000KB/sec with the same motherboard.
There are some jumpers on the board that add VLB wait states. I believe they are not well documented. They should be near the VLB slots. I would compare a photo of your board to another one and set the jumpers accordingly. They also could be jumpers on the VGA card itself.

The one I have is branded Tekno Pro from a small local company called Teknorama. They seem to be around even 30 years later 😀

I wounder if the warrenty is still valid 😀

I have the original invoice for it somewhere. It was delivered as a DX40 but it was upgraded to a DX4 100 about a year later. 16mb ram and two harddrives for a total of about 1.5gb. Cirrus Logic 5428 and SB16 with a Creative CD-ROM.

Oh wow I love that! Certainly a much more practically sized tower than this oversized beast 🤣.

Ok guys I have some benchmarks for ya. Ran VIDSPEED with the L tag for VGA and it got a pretty solid score, up into the list with PCI cards. Pic below. Also ran the standard Doom shareware benchmark, default screen size, no sound, and got 31FPS. 31 seems pretty quick for a 486 so no complaints there, I should have run it before the ram upgrade to compare but I don't want to pull it all back apart now 🤣.

I remember seeing this monitor in an early 1993 issue of PC World. I was always pretty jealous of that glowing LCD screen.
