933.5I just got an L2 Cache for my 6100UNIFIX::HARRISJuggling has its ups and downsWed May 07 1997 22:3915
    I just picked up a 256K L2 cache for my 6100 for $23 ($15 for the L2
    Cache and $8 for shipping), from "Other World Computing".
    
    I don't know if this is the cheapest, but for comparison, The Chip
    Merchant has a price of $35 +S&H.
    
    The system feels a bit faster, but I don't have any test data.
    
    I found it the offer via <http://deal-mac.com/>.  The cache was being
    sold by "Other World Computing".  Their web site is at
    <http://www.macsales.com/>
    
    The cache card is good for 6100, 7100 and 8100 systems.

933.6L2 cache helps my 6100 - most definitlyUNIFIX::HARRISJuggling has its ups and downsWed May 07 1997 23:0510
    I do have an update on the performance of the 256K L2 cache added to my
    6100.  
    
    When I pull down a menu item in Netscape such a the Bookmark menu item,
    it is much faster.  Before it took 1 to 2 seconds (I felt like grass
    grew faster), now with the L2 cache the menu just pops down.
    
    The Cache is definitly helping.  I think it was $23 well spent.

    I added an L2 cache to my 6360 when I bought it a couple of weeks ago,
    and the difference in performance was phenomenal.  I didn't think to
    run a benchmark before to provide quantitative comparisons, but what
    you're seeing is what I see, too.  I can see a real difference in how
    fast old 68K programs like Brushstrokes do their tasks, especially if
    the task at hand is a plug-in activity.  Get that whole plug-in into
    the L2 cache, and ZING!
    
    Now of only I could find the extension conflict that hangs the machine
    entirely too frequently...  :-)
933.8Aids to finding out if you already have an L2 CacheUNIFIX::HARRISJuggling has its ups and downsThu May 08 1997 12:2827
    For anyone thinking about the 6100/7100/8100 cache board, but you don't
    know if you already have a cache, the following might help:
    
        <ftp://ftp.newertech.com/users/ntech/download/cache22.hqx>
    
    This is an application that runs timed loops on memory, and checks for
    when performance drops off as the size of the test array exceeds the
    size of the cache.  Then it tells you how much cache you have, if any.

    	<http://www.thechipmerchant.com/pm7100.htm>
    	<http://www.thechipmerchant.com/pm8100.htm>
    
    The above are a set of web pages that give instructions for installing
    memory and cache boards in the 6100/7100/8100 systems and they include
    pictures of where the cache boards are located in each system.  You
    can use these instructions and pictures to open up your Macs and check
    to see if you already have a Cache card installed, or if the socket is
    empty.

    PS.  For other people interested in a cache for their systems, you can
         often find the instructions and pictures on how to install one at 
         "The Chip Merchant" web site.
