Compaq, NOT the PC/AT. And, not even Compaq, although it comes the closest, as explained below. The PC/AT employed the Western Digital WD-1003 board level controller in an ISA slot and an MFM drive with its associated industry standard (Seagate ST-412) 20-pin differential data in/data out and 34-pin open collector control cables. The Compaq implemented a forerunner of the ATA physical interface, one which was pretty much compatible on a command level with the WD-1003 but incorporated the functional equivalent of the WD-1003 controller on the drive, although the Compaq drive's physical interface was specific to Compaq. Blame a consortium of other drive manufacturers for the ATA standard, not IBM (nor, in reality, Compaq). IBM had a somewhat similar concept for its higher level PS2s, ones which were roughly compatible with the ESDI standard. -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
