Book Review - Pilgrim's Progress
Copyright 1988 by David W. Batterson
BUILD YOUR OWN IBM COMPATIBLE AND SAVE A BUNDLE, by Aubrey Pilgrim; TAB BOOKS
Inc., 1987, 210 pp., first edition, trade paperback, $14.95.
The title of this book is inappropriate, for a couple of reasons which
I'll explain briefly.
Computer writer Pilgrim's book was copyrighted in 1987 which means it was
probably written in 1986, and perhaps parts were written even earlier. Since
that time, IBM clones have dropped dramatically in price, so that you can now
purchase an AT clone for what you used to pay for the original IBM PC. So it
is not likely you can "save a bundle" putting together your own clone.
And you really would not want to do so unless you have considerable
experience, and could get parts at wholesale. Today's clones are generally
reliable--be careful of certain no-name clones--and you get a one year warranty
at the least. Most clone makers also do a "burn-in" (48 to 72 hours or so) to
make sure nothing is going wrong. Therefore, I recommend you leave it alone,
and forget about building a clone of your own! Otherwise, you may moan.
Secondly, the book spends maybe one-third on computer-assembly
information, and the rest is of a general nature for new computer users.
A better title for this book might have been: "Pilgrim's Progress - The
Complete Guide For New IBM Clone Users," or something along those lines.
Those points aside, Pilgrim does provide excellent, highly useful
information for those starting out in IBM-compatible-land. His explanations
get the technical data across, without sounding like a quality engineer at a
major missile and space company (which he in fact IS). His MS-DOS tips, for
instance, are better than what you find in most manuals provided with today's
clones.
As one who has written software manuals (for various software bundled with
the Vendex computer), I agree totally with Pilgrim about how bad many hardware
and software manuals are. This is one area where a lot of companies will skimp
on quality. As he points out, a well-written user guide means FEWER calls to
the company for tech support. Epson's manuals are first class, for example,
while manuals for the LOGITECH C7 Mouse and Migent Pocket Modem will prove
difficult for the inexperienced.
I spotted one tiny error: a DIP switch is a "Dual Inline Package" switch,
not a "Dual Inline Pin" switch. After using DIP switches, you'll want to call
them "Damned Incredibly Petite" little buggers!
There is the school of thought among some newcomers that "I don't care
about the technical stuff; I don't want to use GW-BASIC; who cares how a disk
drive works?" and similar prattle.
Yes, it isn't important to know that "0110001 0111001 0111000 0110100" is
the binary code for 1984 (yawn...) unless you're a programmer. Or that BIOS
stands for Basic Input Output System--"gee, I thought bios meant a collection
of biographies."
However, the new user shouldn't be a "clone klutz" either. It IS vital to
know how to change the DOS PROMPT to something more helpful than the inane "C>"
default PROMPT. Pilgrim explains this command fairly well. But one of the
examples on page 154 is incorrect (no doubt due to a typo and not Pilgrim's
expertise): PROMPT $P $T $D will NOT produce the display "C:\WS 8:06:29.38 Fri
7-18-1986>" as indicated. You have to use: PROMPT $P $T $D $G. The "$G" adds
the ">" to the end.
More DOS commands such as MKDIR (MD), CHDIR (CD), CHKDSK and PATH are
covered lucidly, as are CONFIG.SYS and BATch files. These MUST be learned if
one wants to use a computer properly.
However, the index is incomplete, leaving out too many terms and subjects:
EDLIN, shareware, ASCII, CPU, CMOS, MHz, MODE, COPY CON, and many more. The
WORM (Write Once Read Mostly) drive is listed in the index as "worm."
Overall, regardless of the book's misnomer, it is a handy reference tool
and I can recommend it. I must add that I enjoyed comments like: "Anyone can
call themselves an analyst or a consultant," and [the text editor] EDLIN "is so
crude and hard to learn that very few people ever use it." How true!
As the late John Wayne might have said of this book, "Thanks a lot,
Pilgrim."
