I don't normally boast of my buys, but this is by far one of my better one's recently. Really surprized nobody else bid on this but me, initial and winning bid... $4.99! Diamond Stealth Trio 64 VLB, boxed w/ drivers & manuals and has already been upgraded to 2MB fast 50ns DRAM.

Zup, Yes I have a feeling it will take some time before I can duplicate EPROM bios chips successfully, but will be rewarding nonetheless should I be able to revive a couple of non-functional cards I currently have or revive one's in future that fail on me. Will look to figure out which EPROMs are …

Guys thanks for the posts! Yea the EPROMs can be removed, all of them seem to be 28-pin DIPs. Willem is ideal... there's quite a few different ones to choose from too. Can anyone recommend on which would be the best / compatible, blank EEPROMs for writing to? There seems to be a few... winbond, …

Hello, We're not getting any younger... and neither is our hardware unfortunately. Over time it can only be expected that things will secumb to gradual wear and use... however, i'm finding it's good to make ROM backups etc and do what we can to prolong the life of components. Regards to old (near …

Fantastic find... a really nice case too! It pains me to think that there are folk out there that are willing to dump their old retro hardware only to be taken and filled somewhere in Africa... so it's always good to see another 386 survived and revived. Good job!

Interesting system, and nice case! I also have this very motherboard... have not tested it extensively for measuring performance but it runs well enough, I do like the additional 2 SIMM bank feature... being able to upgrade the DRAM content to 64MB.

I still have in mind that the Matrox cards had a pretty nifty RAMDAC and were therefore advanced in the picturequality but they never had enough power for gaming. That's why later on Matrox specialized on medical picture stuff. Yes but toss a Voodoo in next to the Matrox and you have a force to be …

Thanks for all the advice... yea I was wondering if the ISA could utilise all 4MB, save for VESA. I manged to find a Tseng 32i thankfully... though I was under the impression that the Hercules/Stealth were all higher end cards more suited to windows/GUI and even though they could do well under Dos, …

If the board has... use the ext batt connection, if not... how good are your soldering skills? The Opti495 board you have... how many VLB slots does it have?

Hi, Could I ask about your Opti495 board? I have two of these boards which i'm still trying to identify. I can't comment on the DataExpert motherboard VLB functionality... but with an S3 graphics VLB chipset, you generally can't go wrong. For a CPU, compatibilty wise... anything that runs off a FSB …

Just took a better look at your collection... very interesting! You have an ATI ISA card which is 4MB!!!? I never knew this was possible... and you have a 25MHz harris! Whilst doing my Tseng 32i research... the phantom came up in a forum with someone giving it good praise. The only two manufacturers …

AWE32's with real OPL3 are the later versions if my memory serves... like the CT3900? Yea that would be great... a 32p or i, not sure if there's much difference? btw, do you have any opinion on the Genoa Phantom 32i? Trade wise that's interesting... thats open to interpretation, what would be …

Will need to look into this a bit more... and it sounds like you have a nice collection of boards. Begining to like more and more this interleaving business.

Interesting... i've never really thought about 486 motherboards interleaving before... was that (at the time) IBM specific? I've certainly heard of graphics card chipsets that interleave memory, such as 'The Tseng'... not sure if (in Dos) there are many other (VLB) chipsets that can match an …

I forgot. I still have one more hybrid board left, but it's an IBM 486SLC2-66 with VLB, so the VLB slots are gimped even further with a 16-bit data and 24-bit addressing restrictions. 32-bit slots on a board that only has a 16-bit 486!? This kind of things puts me off proprietary vendors like IBM. …
