More Hardware questions

[Vaughn Treude]

Hi,
    I forget what EDO stands for, but a lot of mother boards can handle 
either type of memory, if you set in BIOS.  I don't think you can mix EDO and 
non-EDO, though.
    The easiest way to determine a device's interface type is to look at the 
connector on the back.  IDE's (all the ones I've dealt with) are almost 
always 40-pin connectors.  The EIDE ones use the same connectors as the old 
ones; they just need a new improved cable.  SCSI-I and SCSI-II device 
connectors in the old days looked very similar to IDE connectors, but they 
had 50 pins.  The newer wide SCSI drives have a high-density connector which 
I think has 68 conductors.  You can buy a converter to adapt that to a 50-pin 
cable, but I've never tried one so I don't know how well they work.
   Also, I've never seen a PC motherboard with an on-board SCSI interface, 
but I believe they do exist - they're just not common.
   Hope that helps.
