Something different. I have been slowly setting up a clean 1994 486 VLB system, but had some doubts about the casing. Never owned branded PCs. Custom builds all the way, tuned for maximum performance. All bells and whistles removed - only the essentials left. The standard metal cases were always a …

Hi Tetrium, i keep posting info from time to time here: https://www.vogons.org/viewtopic.php?f=25&t=65395 It is not structured as a proper "research document", so some of the points may not be obvious, but if you skim through it, you will notice the pattern. Long ago i noticed some of that stuff …

On 486 class machines vlb adapters are for sure faster at dos graphics than pci counterparts, considering more or less similar time period - to say 1993 - 1996 and even early 1997. For windows graphics is the opposite: pci > vlb. If you test this on pci/vlb mobo - numbers will be somewhat lower than …

I have the same motherboard with the same problem. Also, there are at least two more reports out there about similar mobos and chipset. All these early, wide format, 386 mobos are slow and clunky.

Octek Fox-286 with Headland chipset. Octek had couple of hits with their hardware back then. 286 Headland chipsets were very common ... and just as much unexciting. So, i was not sure what to expect here. The board is of good quality. Had to solder a crystal oscillator socket. Takes up to 4 Mb of …

@Firage Is your L1 running in WB or WT mode ? Wonder if the EIDE controller is potentially able to work around WB L1. Thanks.

I had com, or was it lpt tablet back then. It was super cheap, but did the job. In fact i remember buying 10 of them and selling them to friends at no profit. Was there ever an argument about wolf and doom with or without mouse ? That question does not make sense. Also there was (is) a better …

DTK PTM-1632C is an interesting 286 motherboard. It allows to combine SIMMs along with on-board memory for maximum amount of 5 Mb RAM. Cannot remember seeing this in other boards. BIOS is custom DTK software that was super advanced for 1990 - menus and stuff. It is very similar to the one of the 386 …

Some background for context, before asking the questions: In general i have been more into graphics and programming than audio, but always cared to have good PC audio hardware. This translates to my retro hobby as well. So, i have plethora of SoundBlasters, ESSs, other sound cards, Sound Canvas, etc …

@firage This is some great IDE perfomance for sure. Better than VLB SCSI controllers in 10mb/s mode. Can you expand on your experience with EIDE2300Plus ? It has a bios -check, needs a driver - check. What options it provides for its configuration ? Thanks.

Really cool rig. Great job Firage ! @CoffeeOne In my opinion caching controllers won't have much, if any, effect with CF storage. From all 486 class motherboards and controllers that i messed with, Asus PVI seems to be the only one doing the PIO4 mode with real 10Mb/s transfer rates, which is at …

Tried early today few things. - Shortened that line - removed the other inductors and shortened the other line. - swapped the existing inductors between the lines. Win95 refuses to recognize the Voodo. I am hesitant to take components from other boards to get two of these inductors in place. It …

Sharing info about two more 386 motherboards. Biostar MB-1333/40AEA-Q Neither good or bad board - from the middle of the pack. Does not overclock at all. Pretty stable. Does what is supposed to do. Trying to think of anything unique about it but - nothing comes to mind. https://www.petershipkov.com/ …
