Message-ID: <20700001@hpihoah.HP.COM> Date: 9 Aug 90 17:09:16 GMT Organization: Hewlett Packard, Cupertino Lines: 7 I just purchased a 20 Meg Supra 500XP drive with 2 Meg of ram for my A500. The documentation says that an external power supply is "optional" and may be needed. How do I know if I need to buy an external power supply? Will the system just not boot up if the 500's power supply is inadequate? Or will I get random memory losses which could be hard to detect? Thanks for any information you can provide.
