Nope, I bought my board from Germany. http://www.ebay.de/itm/Mainboard-ASUS-P-I-XP5 … =item566859e270. The P55T2P4 (AT version) I found in the US: http://www.ebay.com/itm/Asus-P-I-P55T2P4-Moth … =item233f12655f

btw, the XP55T2P4 was bundled with ASUS I-A16C sound card (Vibra16C). I have the card but not the board.
It's a kickass motherboard. It was actually THE motherboard to get in 1997 as reviews was going crazy for it. The AT version is the latest revision and full 512kb L2 cache. I already have a TAG RAM DIP ready to place in it.
The XP55T2P4 is revision 1.3, and is from early 1996. It does not support higher FSBs than 66mhz and it does not even officially support the MMX CPUs. It is missing a voltage regulator for 2.8V. Also it is the only ATX board I've seen with a Dallas RTC chip and not a coin battery. I choose to go for this board because of these quirks, but also since it had an ATX power supply connector (other boards, even later revisions I've seen has only AT connector).

Great stuff, love the atx version.
They are no that uncommon as they were very popular back in 1996/1997, so you might be in luck someday 😀
@gramcon, I think that the third power connector on the 486 board is for PCI cards that need 3.3V.
You're correct. Not necessary to connect unless you have PCI cards that need it.
How many programs/games could use Roland MPU-401 (MIDI) on MCA systems?
Not known, but a few. Raymangold have a thread about it here on Vogons. I plan on using it in another system than his, so hopefully I'll get more working.
