From what I understood, Sound cards usually are emulating a MPU-401 in UART mode (or "dumb" mode) which works with most MIDI modules but not all. There's some MIDI modules that require an "intelligent" MPU-401 interface, that's where the Midiman/MQ/Roland MPU-401 interface cards come into play.

Yeah - forgot to mention that. The EPROM needs to be blanked first (I dunno why I omitted this).

For the BIOS you should need a 27Cxxx [where "xxx" is the capacity of the EPROM, such as 27C256, 27C512...] EPROM (or equivalent, there should be a model number written on it), something to flash it (either a dedicated programmer [the safest option], a NIC with a EPROM socket, or the risky "hotswap …

I've bought this ASUS M2N Sli Deluxe. It came with AMD Athlon64 X2 5000+ and 4 sticks of 1GB DDR-2 PC2-6400. Paid $12. The motherboard is a bit dusty, but I'll take care of that. The nice touch is that it has I/O shield. I have the same board, beware that it can be a bit fussy sometimes, mine would …

Some folks on another forum had told me it's some kind of bait-and-switch scam, in which the seller baits a potential buyer with an item, only to trick the buyer into buying something more expensive. (or so that's how I understood it)

I belive there are two types of COM port headers, there's a chance that your COM port brackets are wired for one type while your motherboard has the 2nd type.

Ok thanks, I've ordered a plastic screw driver set. Could not find the cpu tool on ebay. And is Mr. Bios worth keeping? The motherboard has extensive battery corrosion, so I'm tossing it. Yes. There's a topic in the software section that has a list of all dumped MRBioses. There's a lot of MRBioses …

Since it's a trayloader it should have an internal DA-15 (Apple VGA) connector from which you can send a regular VGA signal (640x480 iirc) through a DE-15 to DA-15 dongle.

nec_test.exe should work under Windows to test monitors (for the VGA ones at least), I don't know if there's an alternative for the 5153. I think there was some dedicated TPG (test pattern generators) that you could hook up to a monitor that you wanted to test, though they are rather difficult to …

They'll work just fine but obviously you won't be able to boot from a SCSI HDD connected to this card.

IBM Ultrastar 9ES "Draco", I always called that one the "Typewriter" HDD as it makes a bunch of clickety-clacking (a la Seagate ST-251) when it spins up and initializes.
