- First Impressions of the IBM PCjr

- Introduction
-
- This article was written with the
- intent of describing my first
- impressions of the PCjr and hopefully
- it portrays a typical first-time IBM
- user experience.
-
- I think the single most asked
- question will be "why buy a PCjr?"
- While not wishing to describe in
- minute detail all of the factors
- involved in my decision, let me
- briefly give my own reasons for
- making the investment in the PCjr.
-
- I had owned an Apple II+ for a couple
- of years and was most happy with the
- price/performance it provided.
- However, I had concluded that:
-
- 1. I wanted to stay abreast of
- current technology.
-
- 2. IBM is now the leading personal
- computer manufacturer.
-
- 3. I wanted an 80 column screen.
-
- 4. I wanted color.
-
- The logical consequence of item 1 is
- the realization that you'll be
- selling or upgrading your personal
- computer every two or three years.
- Further, if you want a reasonable
- return on your investment you had
- better make sure that you don't buy
- the latest technologically advanced,
- feature packed product. Also, to
- increase the marketability of your
- now secondhand personal computer,
- it helps if the company that
- manufactured it is still producing.
-
- I reached the conclusion that IBM was
- the way to go. Having decided on one
- vendor I was distressed to learn that
- an appropriate IBM PC configuration
- would cost approximately $4000.00 at
- IBM list price. The IBM PC would
- have been for home use and and no
- amount of justification or
- irrationalization could allow me to
- spend $4000. When IBM announced the
- PCjr, it solved my problem at an
- affordable price. I now own a 128K,
- single drive PCjr with an IBM RGB
- monitor and an Okidata printer.
-
- Assembly and Configuration
-
- By following my Guide to Operations
- manual I succeeded in "powering-up"
- in less than 15 minutes. The Guide
- to Operations provides an excellent
- step by step description of how to
- assemble and check-out the PCjr. Once
- assembled, the main use of the manual
- is the cross reference between the
- PCjr and the IBM PC keyboard. In fact
- this cross reference becomes vital as
- the majority of the software running
- on the 62 key PCjr was designed for
- the 83 key IBM PC.
-
- When arranging the PC and its various
- peripherals, remember that its system
- unit is not designed to support the
- weight of a monitor. Also place a
- switch power strip between the
- external transformer and the wall
- outlet. This enables you to power up
- the system with a single switch; and
- when off, potentially prolong the
- life of the transformer.
-
- A discussion of the PCjr would not be
- complete without mentioning the
- keyboard. I am not a touch typist,
- more a four finger and thumb "hunt
- and peck" artist, and I find the
- keyboard adequate. I first thought
- the cordless operation was a gimmick
- and bought the additional keyboard
- cord, but as I had a couple of spare
- "AA" batteries I hooked it up without
- the cord. It is an honest to goodness
- advantage, it provides additional
- flexibility and ease of keyboard
- storage. And its 62 rather than 83
- keys give me less to "hunt" over,
- but compared to the IBM PC there are
- more three-fingered control keys,
- which causes both physical and mental
- gymnastics.
-
- DOS 2.10
-
- Probably the single most difficult
- part of the system for me to absorb
- was DOS 2.10. [as opposed to DOS 1.1,
- NOT 2.0 - ED]. Do not underestimate
- the time needed to master DOS and its
- associated utilities. I haven't
- purchased any additional textbooks on
- DOS, but I can understand why they're
- readily available.
-
- BASIC
-
- Having programmed an Apple in BASIC
- for two years, I spent the additional
- $75.00 and bought the BASIC cartridge
- and manual. If you're not into
- programming, don't bother to buy it.
- However, if you enjoy programming,
- p{ its an incredibly good buy. IBM's
- BASIC is as good as you'll find
- anywhere in the industry, with its
- exceptional repertoire of commands
- and features. It's not lightening
- fast and is marginally slower than
- the IBM PC, but it's able to handle
- most day to day chores in a
- respectable time frame. I have not
- explored the BASIC Compiler yet.
- Most of the literature leads you to
- expect a three to ten fold decrease
- in run times with a compiled Basic
- program.
-
- Software Compatibility
-
- I've had little experience in this
- area, but can guarantee that the
- following are compatible: Supercalc
- 1.10, PC-Write, Multiplan, Q-bert,
- and PC-Man. Programs that require
- more than 128K will not run. Also be
- careful of programs that use graphics
- and require 16K - 32K of your memory
- due to the screen using RAM as
- "display memory", rather than the IBM
- PC which uses memory on the adapter.
- The best advice - try it out first or
- make sure you can return it!
-
- Conclusion
-
- Is a PCjr worth it? If you want to
- play games, I think other machines
- do a better job at a lower price. If
- you want an introduction to the
- market leader without shelling out
- your life savings, PCjr is the
- answer.
