[comp.sys.ibm.pc] Hardware Upgrade help needed

scottw@hcx1.SSD.HARRIS.COM (05/07/87)

  I am considering making changes in my PC and would like any
  information which a knowledgable person could give.

  I have a true IBM PC (purchased 3/82) that I would like to upgrade.
  Currently I have 640k, 2 360k disks, a Hayes modem, cga, and printer.
  All five slots on my machine are full. I definitly want to add
  a 20 Mbyte hard disk.  If I still have money left over then possibly
  an accelerator card.

  The question that I have is this:  Does the power supply in my PC
  have enough power to run a hard disk in addition to all the rest of
  the equipment?  If I buy an external hard disk does this help the
  situation?  I know that most external disk drives have their own
  power supply.  If I add an accelerator card does this require more
  power?

  Some advertisers claim that their hard disks on a card can run on
  a stock PC without adding a new power supply.  Is this claim true?

  In the latest issue of PC magazine I saw a board advertised which
  allowed you to put two half length cards in one slot.  This would
  free up a slot so that I could put in an accelerator card or hard
  disk on a card.  It would seem that placing two cards in the place
  of one would require more power (6 cards instead of 5).  Is this true?

  If anyone out there has added a hard disk to their stock PC
  (with no open slots) succesfully please let me know how you did it.
  I know that this is a rather long note but my hope is to try and
  anticipate any possible problems.  Please send e-mail directly to
  me or if you feel your comments are general enough then reply to this
  note.

   The PC power supply produces a mere 63.5 watts.  It will support 
2 drives and 5 slots.  Any two drives are ok, I think.  I have put a 
20MB hard disk on mine, but had to get rid of the  second floppy.

A hard disk on card seems to follow the rule.  It is a card...

   A power supply upgrade is possible for some $ (under 80 I think)
which will allow more drives, etc.  Another possible alternative is
the externally powered device, or an expansion chassis.  The chassis
gives several more card slots, and room for a hard disk.  It uses
the expansion port on the back of the floppy adapter (as I recall)
so no additional card slots in the PC will be taken.
