Message-ID: <12507@sri-arpa.UUCP> Date: Wed, 15-Aug-84 04:16:00 EDT Article-I.D.: sri-arpa.12507 Posted: Wed Aug 15 04:16:00 1984 Date-Received: Sun, 19-Aug-84 02:05:44 EDT Lines: 13 One thing that is happening in memories these day is that the indivdual chips are getting much larger. What this means is that an individual chip failure becomes catastrophic! If you have an IBM PC with 512K of memory using 64K chips, and one chip goes bad (completely bad, say)., You have lost part of your memory, and if you are technically inclined, you can swap some chips on the board, throw some switches, and bring your PC back up with 448K memory. If you have a Macintosh with 512K bytes of memory (and a 16 bit bus, remember!), your system is now completely dead. For this reason, EDC may become quite valuable... BillW
