re original ibm pc specs in article apr ucbeh san uc edu hoffmamc ucbeh san uc edu writes a hard drive with xt type controller can be added but i recommend not trying a full height hard drive as i have run into trouble with the w supply not having the oomph to spool up those big heavy platters one way to get the system going with one floppy drive and one hard disk on a watt power supply is to first disconnect the power from the floppy drive than turn on the pc you will notice the hard drive having a real difficult time getting up to speed but it manages when booting is finished plug in your floppy drive now it will work ok i know this is not very user friendly maybe you are better off buying a with watt power supply or something like that willem
