SCOPE This guide is designed to take you step by step through the procedures to install and initialize your Corvus disk system for TRS-80 Model II computers. This guide details only the installation and initialization procedures. It does not contain explicit explanations or descriptions of the Corvus disk system and software. Further information concerning your Corvus disk system and associated software can be found in the CORVUS SYSTEMS USER GUIDE FOR CP/M COMPUTERS.
CONVENTIONS The word "Type" is used throughout this guide to mean that two or more characters are to be entered at the computer keyboard. The form of a "Type" statement is as follows: Type RUN SYSGEN (ENTER I Keytop symbols such as I SPACE I within or at the end of a statement to be typed represent a single typewriter key to be pressed. When a keytop symbol is used, press the key to which it refers.
HARDWARE SETUP 1 To use your Corvus disk system with a TRS-80 Model II computer, the following minimum hardware and software is required: D TRS-80 Model II computer with 64K RAM DOne 8" floppy diskette drive D Corvus Hard Disk System for TRS-80 Model II computer with CORVUS T2-H UTILITIES diskettes D CP/M Version 2.
1. Power off all equipment. 2. Place the disk unit on a flat surface, on its base. Be sure the disk drive has adequate ventilation. Also, protect the disk from strong electronic fields by not placing power cords or other electro-magentic field generating equipment on top of the drive container. Since the Corvus disk system is a precision instrument, it must be handled carefully. The disk drive must not be operated when the unit is upside down or at an incline.
Indicator Lights -.------,---, Switches Drive Cabinet Front Panel 3. Flip all of the red drive controller switches to the left, which is the normal position for each of them. Approximately two inches (5 em) below the indicator lights, the front panel protrudes slightly. The four switches are located directly beneath the lights, and up under the lip of the protrusion. .! , ,!, LSI·11 MUX ,,,!,, , FORMAT RESET Switches and Lights 4.
The AC power cord connector and fuse are found at the bottom right of the back panel on all drive models. To change the voltage selection, flip the small circuit board and install the proper fuse as follows: Voltage Selection and Fuses D Slide open the clear plastic cover door, pull the fuse-pull lever to the left, and remove the fuse. D Use long-nose pliers to carefully pull the voltage circuit board out of the fuse housing.
5. Connect the 34 pin flat cable to the disk drive port labelled PROCESSOR on the rear bezel. The cable must exit downward, with the red stripe on the right, as you look directly at the rear of the drive. (Note that this cable must not be coiled because coiling increases signal distortion.) 6. Remove the screws securing the top of your TRS-80 Model II computer and remove the cover. 7.
8. Insert the Corvus interface card into any available peripheral slot in the TRS-80 Model II card cage. Component side of the card should face same direction as the other cards. 9. Connect the free end of the flat cable to the interface card. The stripe should be on the bottom when the card is in the card cage. 10. Carefully slide the top of the computer back on and replace the screws. 11. Tum on the computer. 12. Connect the AC power cord to the disk unit and to a power receptacle. Tum on the drive.
INITIALIZATION FOR CP/M 2 This procedure will create CP1M areas on the Corvus drive. The floppy drives use volume A: and B:, volumes from C: on are on the hard drive. After initialization is completed it will be necessary to run the CLINK program on each computer each time it is turned on. The CLINK program you run depends upon the model drive being used.
type DIR I ENTER I to display the directory and make sure that you have this program. Next, type ONE DRIVE I ENTER I . The screen displays: CP/M now set for a single physical drive Logical drives A, B, C or 0 may be used. CP/M will prompt you to insert proper diskette 4. Make a copy of your CP/M boot diskette. Use the copy of the CP/M boot diskette, and store the original master in a safe place. 5. We need to make a 63K version of CP/M. This is usually done with a combination of the programs MOVCPM.
