Industrial PC motherboard with ISA, PCI, DMA support and Compact flash slot (6x USB 2.0, 6x COM, FDD support with 5.25’ and 3.5’ floppies 360Kb - 2.88Mb). Brand NEW.

i850 based ASUS P4T-E

This arrived today - Canopus Pure 3D IILX

It came with original cables, including an internal pass through cable to the Spectra 2500 TNT card.

I would guess it's a memory expansion card, as it has 8 RAM chips on it. Possibly for a specific motherboard.

I only see 4 RAM chips.

Is there anything on the other side of the card?

I was looking for a KT333 motherboard, but instead this listing turned out to be a Super Socket 7 board - the 1st one I have owned since 1998. A loose 256K async cache module was also included. I thought the fan was bare, but attached was a bill for building a 486, heh!

Can someone identify this ISA card? I do not want to plug it to a PC before i know what it is.

Delay line in upper left corner, thats how some people designed dram controllers back in the day. AST six pack plus uses same method. 4x MB81464 64kbitx4bit rams, 128KB in total.

This controller came in a box with this memory card. May Be they somehow related.
And no, there is nothing on a back side.

this is same thing, delay line in center of the card and also 128KB 😀

Stupid question did you use a new bios battery? I've had a large number of motherboards old and new either not power on/post or just behave and strange unpredictable ways with missing or dead/low bios batteries.

I did not try a new CMOS battery. I've never had a board not boot with a dead or missing battery, they just don't retain settings or date/time, so that would be news to me. Worth a shot I guess. I'm going to try a few more things before throwing in the towel though. I really want it to work.

I was totally dumbfounded the first time I figured that out. So I went back through my container of non-working motherboards and trying new batteries had 15 suddenly spring to life. I did as a control pull the battery and try again and sure enough they all played dead. So it's one of my go-to troubleshooting steps. My sons socket A system with a Abit KT7a-raid gets weird blue screens or hangs at post when it's battery gets low and my EVGA 680i based XP system will not post with a dead battery.

I think I was angry for a week 🤣 ... be another week getting over it if I find dallas boards doing it.

It's a thing, I had it happen to me more than once.

that's interesting, i really thought that without the battery the board would just forget settings and start up as for the first time

have others experienced that too?

Dell Pentium 4 era machines were known to do this as well. Dead battery and you get no POST at all.

@ATi_Loyalist You'll probably love this.

Scored these from another forum (which me and @Robert B usually frequent). ABIT IS7-E v1.2 + HIS Radeon X1950 Pro 256MB w/ Sapphire HSF.

The X1950 just needed a slight reflow of the bridge chip and it's now back in business, I'll be also pasting a heatsink over that bridge bugger so it won't die again, now that I also added a thermal pad from a dead X1650 Pro.

Fan on the IS7 NB isn't original btw, it's from a dead ASUS K8N4-E northbridge cooler.

Oooooh yeah! Always wanted an IS7, they were excellent overclocking boards but didn't sell the volume that Asus did, not easy to find these days!

I have a couple AGP X1950s I need to test, @PcBytes how did you reflow the bridge chip?

Interesting! Did it come with ram?

No. It's mine.
It was saved from recycling. Had to purchase 28 kilos of scrap. But it was worth it.

I wonder how many 'dead' mainboard this conversation revives 😁 I didn't know that, too

Doh! My bad, guess I'm not the mathemagician I once was 😀

Took a chance on a listing for an i810 board that mentioned a Tualatin was already installed. Amazingly I got it without any other bidders, and surprisingly the seller didn't go in a huff and cancel the listing for not clearing an unstated reserve price. So that's the second PIII-S 1.4 I've obtained this much cheaper way.

The CPU is bound for a Compaq server board (hope the differing S-Specs don't matter), while the GA-6IWFL isn't entirely junk as The Retro Web says it supports VIA C3. I like to see if I can put these old i810 boards back to use in low-power roles. i386 Pi-hole, baby!

Didn't buy this retro stuff today, spotted at Value Village, Fennel Ave, Hamilton if anyone interested. Was there 3 hours ago as of this post. Rage II+ DVD PCI, BrookTree AMC riser Tuner card for that (analog, ISA mechanical support and power), two PCI wifi "G" cards. External HDD unknown capacity was probably a PATA 3.5 inside I think, not 100% though. Those were all on the small electrical shelves, then there was also a system unit on the larger items top shelf, HP something or other, mATX case I think, C2D 4200 or something like that, not sure if it was worth sticking a quad in but $9.99 and you get a case and spare junk.
