Message-ID: <1228@cbmvax.cbmvax.cbm.UUCP> Date: Tue, 13-Jan-87 18:38:03 EST Article-I.D.: cbmvax.1228 Posted: Tue Jan 13 18:38:03 1987 Date-Received: Wed, 14-Jan-87 20:05:59 EST References: <320@rlgvax.UUCP> Organization: Commodore Technology, West Chester, PA Lines: 29 One thing I forgot. My mom uses her C128 as a Midi sequencer, data base manager, and store display in the music store she works in. The data base program she uses is called Perfect Filer, which, while not as powerful as SuperBase, does a respectable job of managing her files of keyboard students. If you want the details on why a C128 can come close to and sometimes even beat a basic PC clone, here they are. The C128 in 2.04 MHz mode completes 1 memory cycle (reading or writing one byte in memory) in 490 nanoseconds, a standard PC clone running at 4.77 MHz completes 1 memory cycle (reading or writing one byte in memory) in 839 nanoseconds. Both machines are 8 bit machines, from a hardware point of view. The extra speed in some cases of the PC is that the PCs 8088 processor contains more registers (translates to fewer memory accessess, register operations are always faster), contains a 16 bit ALU (16 bit math is built in, versus programmed in a routine as on the C128's 8502), and the 8088 has built-in memory banking, versus external banking, so memory management on the PC can be faster, and can address more memory. PC disk access is faster because the PC uses a processor controlled parallel drive, versus the serially accessed drive on the C128. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Dave Haynie {caip,ihnp4,allegra,seismo}!cbmvax!daveh "You can keep my things, they've come to take me home" -Peter Gabriel ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
