Thus, in mainstream machines, you'll see things like ISA slots or floppy drives still. Heck; the whole x86 architecture is basically just bolt-on instructions to the previous architecture, with a lineage going all the way back to the Intel 4004. And while some of the backward-compatibility feats they've pulled are nothing short of miraculous, our blind insistence on backward-compatibility is at the point where it's holding back the state of the art more than advancing it.

      OK. Ignore the x86 architecture bit completely, and just look at the add-ons you're addressing - ISA slots, floppy drives, RS232 ports, parallel ports, PS/2 keyboard/mouse adapters.

      For instance, RS232 ports: What exactly is wrong with an RS232 port? Why is it "worse" than a USB port? There's no difficulty in actually using an RS232 port - UARTs are cheap, they're brain-dead easy to interface to, and they support rather modern interface methods (DMA, etc.). They are, however, low speed - but of course, for low speed operations that's all you need. You will never need high-speed data transfer to your keyboard or mouse - they're inherently low data transfer devices, since humans are slow.

      Same goes for ISA slots and parallel ports. They don't hold back the state of the art. They're add-ons. If you don't use them, they don't do anything. It's just a memory space that doesn't get accessed. If you're complaining about their implementation on current PCs (the fact that they sit in I/O space, take up IRQs, etc.) then you're complaining about the BIOS, not the peripherals. I really didn't see the point of replacing the PS/2 keyboard and mouse. They're just serial devices - they interface via the same method that UARTs, etc. get addressed, which is ridiculously easy to interface to.

      There is nothing fundamentally wrong with legacy components. Interfacing to a UART is trivial. Much more trivial than with USB, in fact. There's no reason a "clean" design of a PC couldn't have a serial port, ISA slot, ATA hard drives, and everything else.

      Even the x86 architecture thing is 'not that bad'. Take the x87 architecture - everyone complains about the FXCH instruction, because it IS stupid, but on the P3 and Athlon (but not the P4 - one reason the P4's FP sucks) that instruction's 'free' - it takes 0 clock cycles to process. There's some overhead involved with it, but it's not clear to me that the small gain from fixing the overhead loss would offset the large loss of not being compatible with large portions of x87 software. And it's not clear to me that the overhead couldn't be compensated for in some other way, as well.

      I think it's a good thing to have a lowest common denominator when dealing with hardware. I think it's a good idea to always have the floppy drive to fall back on.

      I ran into an instance just a little while ago where I had to have one. I tried to make my primary hard drive the drive which was on a Raid controller. For some reason, windows XP didn't have the driver for my onboard promise ata100 raid chipset, and couldn't find the drive. So, in the installation procedure, i had to load an external driver ("press F6 to load a 3rd party scsi or raid driver"). The only option for loading the driver was a floppy - can't do it from a CD (or at least i couldn't figure out how to)

      But, it's nice knowing that, if nothing else, you have ps2 ports for any old keyboard and a floppy drive for booting emergencies. Proven technology is a good thing. Besides, why throw out an essentially good design? Yeah, as the article says it's all based on the AT spec, but, we've gone beyond 4MB of ram, we're no longer using AT keyboards, we've ditched the com port mouse, we're using 15 pin SVGA monitor plugs instead of the oldskool 9-pin, our ram isn't 30 pin or 72 pin simms anymore, we're using 168pin sdram, and even that's on it's way out, in favor of 184 pin ddr. The BNC network connections are gone, as are the 15 pin connections. We're using ATX soft-off power supplies now. I haven't used an ISA slot in 4 years, and it's been 2 since I've owned a motherboard with one on it (well, that's a daily user anyway).
      I say, let these things work themselves out. Compared to the 1984 picture in that article, most of our computers are legacy-free - think about how many pieces of hardware you have right now that would connect to a 286. My speakers? My floppy? Mabey the hard drive? Yeah, that's about it.
