This week I received a voodoo 1 and a voodoo 2 card. Seller had it stored away for years and couldn't test them any more. The voodoo 2 turned out to be working fine (yay!) But the voodoo 1 didn't. It seems there were two problems. 1. One leg of the 500-0004-02 chip was bent and touched the leg next …

My opinion: if you've got any PCI voodoo already: just put it in. It won't harm. If you have to buy: think about it, are the current prices worth it? It's your call :) Open GLand direct 3D are handled by the Geforce better any way, so you just want glide support. I guess you could just try soft …

Well, have there been any btx boards with ISA made ? The PCI part can't be reverted so it doesn't matter ^^ [PCI 5v and PCI 3.3v Walking into the room] (Sorry couldn't resist) These are mirrored on the board, notch front or back. The idea of orientation of components is pretty viable. I'd say there …

It's been a while since the last post, but the story continues. As with all fairytales it starts with someone bad and ends with a happily ever after. I had to take another look at the card once again and noticed there were three connectors loose (rubbing then gently with some tweezers) Two of them …

One of my completed is a Philips P3105. NEC V30 8mhz 768kB ram (!), Both 3,5dd and 5,25dd fdd and a Miniscribe 8425X 21MB hdd. The hard disk is connected too the onboard xta controller. Worked fine until recently. The number of bad sectors is increasing fast and damaging all kind of files. So I …

A bit of a long shot: These old boards do have a lot of thru hole solder joints. Maybe there are some joints bent and shooting something? Even longer shot: might there be a trace or joint damaged that is supposed to pull down a reset signal?

If you insist to leave the drives in place, there is always the primitive null modem and faster laplink cable. Just look them up on Wikipedia. Considering you can work with floppy disks, I guess you have a computer that will run a Windows 98 boot disk. Both computers need to run DOS for my …

MB-4duvc is the perfect example of Jumper Paradise. Miss one jumper and all may fail... Nott sure what the board does internally, but it just won't post on some settings. I had this once on my board when testing stuff and it wouldn't post any more. I ripped off all jumpers for speed and type setting …

That's great! I know it can be a hassle to get things out of the pin count is over four... Better tools would be the answer but that's a little investment that you could consider. My soldering iron is ok-ish for thru hole but for smd almost worthless. And of course getting more and more experience …

Cool, I had the same dilemma some time back. I had to choose between the 408, the ET4000ax and V7 5424. I actually tested all three with Phills bench series and all cards seem to be limited by the ISA bus. My 486 DX50 (not a DX2) makes them perform equally fast, with about 1% difference max. The …

I'm currently upgrading my VLB system. It is based on the Aquarius MB-4DUV motherboard, currently runs a Cyrix 5x86-100, has 32MB 60ns RAM and a Paradise 4030 cache controller. Few days ago I got a nice Cirrus Logic GD5428 VLB in the mailbox, it had 1MB and I upgraded to 2MB. This works fine and …

Just an idea I think of for a bit of time now: use some piece of PCB to fit. Cut them out of some dead motherboard or have them baked. There are some really cheap bakers that could provide some more or less ok-ish PCBs, which make it look cool. It's like looking into a case stacked full with PCBs. …

Upgradable to 2MB for higher resolutiond or more colours. Makes me wonder: the 5428 should be quite a bit faster …

Most baby at boards will fit in a P3 time full ATX case, as the ISA/PCI slots will be on the right position. Above the board will be done empty space. Just make sure there are enough screw holes to put the spacers in place. You could create your own backplate from a blank one or just some aluminium …

The slot on that board is not for a cache board as far as I am aware. It is to add extra RAM via a full length ISA plus the special 32-bit slot. Waterbee told me that it has no cache. Pentiumspeed told me it has cache. Now I'm confused too. Looking at the boards pictures I didn't find any dip chips …

Full AT megasized!!! Just count the number of components on there! This is a very early board, clearly. The lack of cache is made up more than twice by the coolness factor :D This is not a McLaren, but more like a Mercedes. Not too fast, but clearly beautifully designed and build with care. Ok, back …

I managed to set all settings to lowest timings in the bios setup and it …
