Some stuff from the Bay and Mr. Bezos arrived today.

I bought a used ASUS XP55T2P4 Rev.3.x mainboard with 256KB cache onboard and an empty slot for a COAST module. In the package was a, apparently NOS, ASUS P55T2P4 Rev.3.10 mainboard with 512KB cache onboard. I’m trying to contact the seller to sort it out, now.

Why do you need to sort something out? I guess you are after the 512MB cachable area. If that is the case, the board you posted is just fine. It has the low tag bits in the small Winbond chip that is soldered to the board, and you have a socket to add a 16Kx8 or 32Kx8 chip (only 16Kx3 is actually used) to upgrade to the full cachable area. With the extra tag RAM and 512KB cache onboard, the 430HX is maxed out, so I don't see any need to get a different board for better performance.

because the XP55T2P4 is an ATX and the P55T2P4 a baby-AT board :p quite a difference.

trying to clear up my package backlog x3

CH Throttle, for all I can tell this has never been used, just a few more CH Products missing ^^

Terratec Aureon Sky with envy24

this intruigingly good looking C-Media CMI8738 card... "Nightingale PRO 6" ^^

two Morse KP800 cards, CL-GD510/520 32 and 40Mhz, one definitely in better shape than the other

and another ISA SBC, the edge contacts are heavily corroded for some reason (came from the same lot as the worse condition KP800 above), also some damage to the IDE but I hope it'll still work.

That right one seems to have been rather common with OEMs, I've had multiple machines with it (specifically very late 486/early Pentium stuff). Have yet to have one fail on me, which is more than can be said for the awful Apple CD-ROM drives from the mid-90s.

Do you know if it works on IDE or it needs proprietary connector? Maybe a sound card with Panasonic/Matsushita connector?

I finally find an exact case like the one I had back in the 90s in my first PC! It's missing few details (ie. 3,5" bay bracket) but nevermind...

I have all the parts now to make almost exact replica of my first PC!

It also came with this intersting 386SX 40Mhz motherboard with MR BIOS. PSU in this PC was shot, so I wonder if the motherboard still works... I will test it this weekend.

Yesterday I bought a desktop and it has the exact same sound card... coicidence...😀

That's some ESS based card... not the best, not the worst either... I'm not a big ESS fan unless it's Maestro-1

What is it about Maestro-1 that you like so much? That card doesn't even have proper ESFM..

There might have been different models but the last two I had were both IDE drives, fitted to OEM machines (an IBM Aptiva and a Compaq Presario).

It's an IDE, just tested it and it works... but I forgot how slooow this thing is... 😀

Yes, ES1868F, it has a wavetable and an IDE header. It's not a Sound Blaster, but still it's an interesting card

Was it common that these large AT cases came with baby AT boards?
I thought baby AT boards were mostly used in mini towers and full size AT boards were used in these.

The "Baby AT" form factor allows boards that can almost reach the front of the case, basically covering the entire tray of either a desktop or mini tower case. Full AT is larger, and extends up beyond the keyboard connector, those are not as common as Baby AT ones, and are usually seen in full towers as they don't fit in the regular smaller cases (AT (form factor)).

The board posted by Han Jammer would be a "teeny tiny baby AT".

You are right, I have tons of these, they are 6,5 x 8,5" (17 x 22 cm) instead of the baby AT 13 x 8,5".
I'm still wondering if it was common to use these tiny boards in large cases like that.

I haven't purchased this but I don't think it deserves it's own thread.

Does anyone know what this board is? Looks like some kind of industrial 386, but what's with the extra long ISA slots? Something proprietary or just a very uncommon interface? Also, there doesn't appear to be a keyboard port.

These are the best pictures I could get of it from a lot I found online.

Pretty sure that those extra long slots were for 32-bit memory and other upgrade boards.

I'm actually wondering if that is a dual socket 386 board. Certainly looks like it to me.

Could be that it is from a Compaq SytemPro server or similar system:

Thanks for the info. That's the best lead I've seen. I probably won't be able to buy it, but I've at least asked the seller about it. We'll see. 😀

As I've stated in my original post, the one I ordered is a XP... not a P... with a coin cell, ATX form factor and 256kb onboard cache and a COAST slot.

Nothing in particular. I had (and still have) it back in the 90s and I like how the PCB looks. Also one of the first PCI sound cards and not as common as Yamahas, Live!, Ensoniqs, Aureals...

Yes, very common. For late 386s especially.

Here's about 20% of my $25 scrap lot that finally came in today. I'm extremely surprised everything came in good physical condition despite the box being ruined by FedEx. One board is for sure dead (EVGA X58 SLI), but the others look promising. Very little to no bent pins on anything, including the CPU's. It is going to take me some time to go through the rest. I have about 15 more motherboards and 30 add-in cards to go, plus a dozen or so CD/DVD-ROMs and Floppy drives. It looks like someone just gutted a bunch of PC's and sold off the parts. There's definitely more than $25 worth of stuff here. 🤣

Wow that is quite the haul. I'd definitely say you got way more than your money's worth.
