            Add a Hard Disk to your Computer


The recent computer slump has resulted in massive parts dumping on the
part of the computer manufactures to the surplus market.  I am sure that
you have seen all the ads in the papers hawking IBM ten megabyte drives
for less than $500.  Let me tell you how you can add a hard disk to your
computer.

All of the "84" series computers come with the larger power supply and
the necessary power wiring for two drives and the hard disk controller.
To convert to a K10 simply involves unplugging the lower drive, adding
the controller and host interface boards, and plugging in some new
cables.

The following is a list of the needed parts:

The hard disk itself

The hard disk controller

The software

Interconnect cables

Hardware
    8 4-40 1/2 in spacers
    4 4-40 1/4 in flat head screws
    12 4-40 1/4 1n binder head screws
    8 #4 nylon or fiber washers

The hard disk is available from many sources.  In the December 
Byte, Advanced Computer Products is selling the harddisk for $229
with a one year warranty.

The Western Digital controller is also a standard part.  It's 
list is $295.  Xerox surplus outlet has them for $75 as is (the 
five I have purchased have all worked), S100 is supposed to have 
them new for $200, and ERAC has them used with warranty for $200.

????????  For a twenty meg  HD????  I THINK NOT!!!

Well, this little article was retrieved from a Kaypro source and
probably dates back to the late 1980's era, before the advent of 
massive Harddrives and cheap parts.  First of all, imagine your-
self back then; only about 10 years ago; with the computers we
used then-compared to today.  Then figure out the value of your 
money in buying power then, compared to today's value. Now, look
at the price we pay today. $50 for a controller, maybe $20 for a
harddrive-used, $30 for a power supply and assorted cables need-
ed, and free software to access it.   WOW!!!  Maybe now IS the 
time for you to persue that harddrive after all.  It seems to 
be PRETTY inexpensive by all standards, doesn't it??  If you 
don't know where to get ahold of the stuff, give a holler and
someone will help you get it and help set up your ADAM with it.
