Introduction
Congratulations on selecting the TRS-80 CR-510 Card Reader! With this Card Reader, a TRS-80
Computer, and standard marked or punched cards, you can:
• Automate data compilation.
• Evaluate surveys and polls.
• Correct multiple choice tests.
and more!
The CR-510 Card Reader is designed to connect directly to your TRS-80 Model I/II/III via the
Computer's RS-232C connector.
The Card Reader can be controlled either manually via switches ("hardware") or through your
program ("software") and can read cards that are at least 15.24 cm (6") in length. A General Purpose
Standard Card designed for use with the CR-510 is available (26-1240) and, with the optional 14"
Card Holder, cards up to 35.56 cm (14") in length can be read.
Note that the Card Reader requires a special "driver" routine to communicate with your Computer.
This driver routine must be included in every program you write for the CR-510. (See Chapter 5 of this
manual.) Radio Shack also provides applications software for the CR-510. Instructions for using these
programs are supplied with the individual software packages.
