Episode 4 - 486 Vesa Local Bus computer parts review

[@dmitrys9852]

I like it. This video remembers me my first PC - Am486DX4/100, 8Mb RAM, with 1Mb Cirrus Logic VLB video. In mid-90s it was cool PC!

[@ComputerCaveman]

Indeed it was. The DX4/100 was a serious CPU in the 486 family!

[@brostenen]

It is funny. I think of 486-VLB boards, as the last proper AT class PC. When they began to put everything on the motherboard, hell just broke loose. Or to say it mildly. A real PC, need things to be on expansion cards. That way it is easier to seek the error or failure. Today we throw out the mainboard. Back then, we just changed one card.

Oh, I also like those old Creative cards. Quickly designed and thrown on the market to be QCed by the customers. Hot words: #5revisionsofSBPro, #hangingnotesbug, #SBProcompatibilityinmono, #lawsuits, #noisyashell Always liked (and still do) Aztech cards more

I built a bunch of these vesa machines.... But when our office upgraded operating systems the next version of windows wouldn't support vesa or at least most of the vesa cards... I'm not sure if it was the upgrade to Win 98 or to Win NT.... I also recall that the vesa cards didn't play well with plug and play cards and OS's... I likely still have a bucket of vesa cards somewhere in my basement....

[@DavidStarkers]

Lots of interesting info mate, thanks.. I've always wanted something with a VLB too lol.. jealous

[@ComputerCaveman]

Thanks, I need to polish video production and other stuff, but I am doing my best. Honestly I can't explain my love for VLB. It was mostly crappy ...still love it thou.

Good video. I certainly approve of your choosing the Cyrix processor for your 486 build here and I am also a fan of the quad speed drives as well, plenty fast enough and quiet. That green heatsink on those chips is just held on with double sided thermal tape, it's not too terribly hard to take the heat sink off of one, though there is not really any point to doing so. I quite like the case front also. Very proper for a 486 or Pentium build in my mind. I am curious though, why did you decide to go with an ISA controller card as opposed to a VLB controller?

[@ComputerCaveman]

Hey, great videos you've got. Ah, yes ...It would certainly improve disk subsystem performance with like 20%. I simply do not have one that is good enough, only faulty units that are beyond normal repair ... when I find one I will probably compare it with the current IO controller and a SCSI ISA one. It is tricky though because shipping charges to Bulgaria are often more than the price of the item itself.

[@MarkTheMorose]

Great video, lots of information.

Fantastic user name! I'm subscribed now.

[@ComputerCaveman]

Thanks, I appreciate it!

The worst most dangerous cards to put in a PC, they could break and needed so much force

[@HamburgerExplosion]

I've got this same motherboard (or very close to it, anyway). My cmos chip and controller chip are made by bioteq though and run off a 3.6v battery instead of the 2032 in your video. No solder-bridged pins. I'm guessing maybe yours is a later revision, and rather than re-print the circuit boards, they used solder above on the different cmos chip to fit its needs. (tie extra pins to ground so they don't interfere with anything probably...? you could confirm that by continuity testing from the solder blob to any ground) It would be nice of you to let me know what pin the positive lead of the cmos battery goes to, since I think my trace got eaten up by corrosion... I have to reset BIOS settings every boot... :-) (remove cmos battery, continuity test between positive lead and every pin on that chip...)

[@ComputerCaveman]

Hi, sorry for the delay. I may have soldered the CR2032 socket myself but I can't remember. I usually do that to prevent possible leaking especially if the board has its pins for CR2032 socket printed. My logic is ... if it has them printed it will probably work. Some CMOS logic thou, especially on old systems, do not tolerate the voltage drop from 3.6 to 3 volts and behave erratically, but mostly they work. Will probe soon and let you know :)

[@RuruFIN]

Always when I see a VLB graphics card, complaining about today's high-end graphics cards feels weird.

[@scalamasterelectros3204]

Dud you made me not want to get in to vlb it sounds like a masive headic
