The employee price applies to components purchased with the system unit.
What is the fastest way to get one? (9/18)
Buy it from ComputerLand. Put in your order now. You won't get the
employee price that way, though.
What if I want the employee price? (9/18)
Mail the information request card in the current issue of THINK magazine
to Boca Raton. If you haven't received THINK, mail a letter to:
International Business Machines, Inc.
IBM Personal Computer
Employee Purchase
P.O. Box 1328-E
Boca Raton, Florida 33432
Include your name, employee number, IBH location, and home address in
the letter.
Employee Questions 2
** IBM INTERNAL USE ONLY **
What is the first day order window for employees? (10/7)
All employee orders received before October 31 will be pooled, and a
random selection will determine the delivery sequence.
Only one system per employee will be placed into the first day order
pool.
If you place multiple orders before October 31, Boca Raton will pick one
arbitrarily or they may contact you.
Boca Raton will compare serial numbers on all employee orders to keep
employees from ordering multiple systems in the first day order lottery.
That means if you have multiple IBM employees in your family, you can
get into the lottery multiple times.
Do have to order by 10/31 to get the Employee price? (9/18)
No. Employees should be able to get the discount at any time.
Can I get a Special Price on new announcements? (10/7)
Boca Raton indicates that the discount will be available only with sys-
tem units. If a new announcement occurs~ an employee price will be
available on the new component. However, to get the employee price, you
must order a (new) system unit.
5 If a new announcement occurs before you receive your system, you may
5 cancel your order and send in a new order. You will get a changed (that
5 means later) delivery date.
5
5 If you anticipate new announcements later, give consideration to delay-
5 ing your order until that announcement occurs. Balance your immediate
5 desire to get a system with the financial impact of the employee price
5 on a new announcement.
When does the payroll deduction start? (9/23)
I assume that the payroll deductions begin when your system is
delivered, but I'm not sure. I'm checking with ISD.
When will I get my system? (10/6)
6 The Employee information packet indicates that employee orders will be
6 scheduled on an "as available" basis. Volume shipments for employees
6 may not begin until the first quarter of 1982.
Employee Questions 3
** IBM INTERNAL USE ONLY **
How many systems can I get at the Employee price? (10/7)
One per immediate family member. Boca Raton defines "immediate ff family
members as your dependents.
Only one system per employee will be placed into the first day order
pool.
Will I have to pay sales taxes? (lOIS)
5 I'm afraid so. The employee information packet states that the taxes
5 you will be charged are the applicable taxes that apply to the pick-up
5 location (dealer store).
What payment options do I have? (1017)
Boca Raton iadicates you have two options:
Pay the total price by check at delivery
Finance the total amount over two years
If you want to payoff the total early, contact your local payroll
department, they will compute the payoff charge.
What is the finance charge? (10/7)
12% in all states except Alabama, which is 10%.
Boca Raton indicates that the computation is:
Take the total price, including sales tax
Hult1ply by 1.13
Divide by the number of pay periods in two years (normally 104 or
48)
The result is the per paycheck deduction for your system
Where can I see the IBM Personal Computer? (lOIS)
5 A demonstration system should be available at most ComputerLand stores.
When will I get my information packet? (lOIS)
The National Marketing Center indicated that the packets would be mailed
during the week starting September 21. The first day order window was
also extended to 10/31/81 for employees to get the packets back.
Employee Questions 4
** IBM INTERNAL USE ONLY **
5 Some employees reported receipt as early as September 28. ! received
5 mine October 3.
Who can submit software? (9/20)
The program is open to the general public with the exception of the few
IBM employees who evaluate submissions. The submitter must be an adult
(age 18 or over).
What if IBM rejects my submission? (10/6)
IBM's position is that if IBM rejects employee submitted software, it
would be a conflict of interest for the employee to market it independ-
ently or submit it to someone else.
6 Several of the IBM Computer Clubs plan to distribute public domain soft-
6 ware for the IBM Personal Computer and solicit employee contributions of
6 software that IBM rejects.
6
6 Those clubs are checking with the la~vyers to find out if such operations
6 will be permitted.
Is there an Engineering Change policy? (10/7)
Boca Raton has no plans to upgrade systems to reflect engineering chang-
es.
Can I write it off my income tax? (10/5)
5 Check with your accountant. I'd suggest two possible approaches, either
5 a professional tool, or as an offset to software royalty income.
Can I change my order after I submit it? (10/5)
5 You can cancel it and reorder. That will probably affect your delivery
5 date.
Do I need a separate Diskette Adapter? (10/6)
6 The Employee information packet lists a diskette adapter, item number
6 1503780, with an employee price of $135. Some employees are confused by
6 this item's significance.
6
6 YOU DON'T NEED TO ORnER A SEPARATE DISKETTE DRIVE ADAPTER, it is
6 included in the Employee System unit configuration.
Employee Questions 5
** IBM INTERNAL USE ONLY **
Should I order the Communications software now? (10/7)
The Employee information packet indicates that the Asynchronous Communi-
cations Support software wouldn't be available until December, and
employees ordering that software wouldn't get a delivery date until it
became available.
I wouldn't mess with it. The employee discount on that item is only
$15.
Note that the hardware (which is the expensive part) isn't delayed, just
the software.

MARKETING INFORMATION
How do I deal with customer inquiries? (10/6)
If your customer is a Volume Purchase Agreement (VPA) candidate (e.g. if
they are interested in 20 or more units), the IBM Marketing Represen-
tative or the customer can call the National Marketing Center at (800)
431-2670. IBM employees can use tieline 254-6840.
If the interest is in less than 20 units, the customer should be
referred to a ComputerLand store, a Sears Business Systems Center, or an
IBM Product Center. ComputerLand is the only active distribution chan-
nel .. in the Los Ange les area.
6 Please don't call me to tell me about your prospect. That is the func-
6 tion of the National Marketing Center.
Where is the nearest ComputerLand? (10/6)

How do I deal with distributor inquiries? (10/7)
The Blue letter states:
Inquiries from enterprises who wish to act as distributors or resellers
of the IBM Personal Computer should be directed to:
Marketing Information 7
** IBM INTERNAL USE ONLY **
Hanager of Pers-onal Computer Harketing
DPD HQ, Department 8C3
1133 Westchester Avenue
White Plains, NY 10604
The NNC told me that they were routing these inquiries to ISD.
Other inquiries, such as firms desiring to develop software or hardware,
or "professional or technical" inquiries, should be directed to:
IBM Personal Computer
P.O. Box 1328-P
Boca Raton, Florida 33432
What promotional material is available? (9/18)
The following publications can be ordered from Mechanicsburg:
G520-3722 For Professional Productivity brochure
G520-3723 For the Educational Community brochure
G520-3916 Hardware Overview flyer
G520-3917 Software Overview flyer
G520-3918 Accounts Receivable flyer
G520-3919 Accounts Payable flyer
G520-3920 General Ledger flyer

G520-3923 EasyWriter flyer
I'm told that Mechanicsburg is out of these, well back ordered, and some
weeks from relieving that backlog.
Marketing Information 8
** IBM INTERNAL USE ONLY **
Is the S-100 bus used?
No.
Is a real time clock included? (9/21)
Yes. You can set the time of day from DOS or from BASIC. The time and
date are lost when the system is bootstrapped or powered off.
Is it simple to start up? (9/21)
You just insert a system disk into drive A and turn on the power. If
you want to re-boot without turning the power off, you press three keys
simultaneously and it re-boots.
Are 5 expansion slots enough? (10/5)
In my opinion, it could be a problem.
The first 64KB fits onto the system board, taking no slots.
5 Each additional memory increment (32 or 64KB) takes one slot.
One expansion slot is also used by each of the following:
5-1/4 inch Diskette Drive Adapter
Asynchronous Communications Adapter
Monochrome Display and Printer Adapter
Color/Graphics Monitor Adapter
Printer Adapter
Game Control Adapter
The maximum 256K configuration uses 3 expansion slots for memory boards,
and probably one slot each for the diskette adapter the Monochrome Dis-
play and Printer Adapter.
You probably wouldn't need both the Monochrome Display and Printer
Adapter and the Color/Graphics Monitor Adapter. Furthermore, the Print-
er Adapter isn't necessary if you have the Monochrome Display and Print-
er Adapter.
System Questions 9
** IBM INTERNAL USE ONLY **
I talked this issue over with the National Marketing Center, they sug-
gested that I probably wouldn't need all the cards at the same time, and
depending upon what I was doing, I could swap cards.
How much memory do I need? (10/6)
EasyWriter and VisiCalc need a minimum of 64KB.
Pascal requires 128KB.
128KB is recommended for VisiCalc.
BASIC won't be able to use much more than 96KB.
6 I don't know how to say this well, but I'd get 128KB minimum if I were a
6 machine language programmer.
What are some sample confjgurations? (10/6)
Use these configurations for comparison, your configuration may differ.
The mlnlmum system for the employee price includes a system unit with
48KB RAM, a diskette drive adapter, and one diskette drive.
In all of the below configurations, the "System Unit" includes:
40KB ROM containing Microsoft BASIC
48KB User memory
83 key keyboard
Programmable speaker
Cassette attachment jack
5-1/4 inch diskette drive adapter
