80 COLUMN DISPLAY DRIVER PROGRAM

80 COLUMN DISPLAY DRIVER PROGRAM The following programs are supplied on a 35 track single sided single-density diskette formatted as a TRSDOS compatible Data Disk. Before inserting this disk into your disk drives, install a write protect tab en the notch on the side of the diskette. OPERATION These programs are all written in machine language and can be executed from DOS by typing the program name (with or without the extension.) SINGLE DRIVE OPERATION l. Boot your system disk (i.e. reset with aa system disk in drive 0) 2. If you are using DOSPLUS you can then use the single drive copy utility (copy 1) to copy the program(s) desired to your system disk. If you are using NEWDOS 80 use the appropriate version of the copy command and make sure that your PDrive specification within the copy command is correct for 5" single-sided single-density. If you are using any other operating system with only one drive you may not be able to copy the contents of this diskette onto your system disk--so check your DOS manual for details. Now that you have copied the desired program off your Master Disk.... l. Boot your system disk 2. When the DOS prompt appears (DOS ready, DOSPLUS, etc.) Type the name of the desired program.... For example type: VIDR <RETURN> If VIDR/CMD is available on one of your drives it will then execute and the DOS prompt (DOS ready, DOSPLUS, etc) will appear again. In some programs a relocation address is requested. Enter the selected address (or <RETURN> for automatic relocation to high memory) and the program will complete. MULTlPLE DRIVE OPERATION 1. Boot your system disk (i.e. reset with a system disk in drive 0>. 2. Install this diskette in any other drive and use the copy command to copy the programs that, you want. If you are using DOSPLUS you may transfer all the files over with the transfer command. If you are using NEWDOS 80 make sure that your PDrive specification for the other drive is correct for 5" single- sided single-density. If in doubt, check your DOS manual for details.

Each of these programs differ in their design and implementation of software character generation and differ in their support of such features as PRINT @. Experimentation with each program will help you find the program that best suits your needs. Of all the programs only C80xl6/CMD uses a combination of both software character generation (beyond 64 characters) and hardware character generation (64x16). This has the advantage of being several times faster in scrolling and displaying characters than the other programs. It has the disadvantage of being limited to 16 lines, and does not offer inverse characters. The following is a summary of the features of the supplied programs: PROGRAM NAME FEATURES CHAR/LINE LINES INV.VIDEO U/L CASE SOURCE SUPPLIED --------------------------------------------------------------------------- VIDR/CMD 80 24 YES UPPER ONLY NO VIDRO/CMD 80 24 YES YES NO D1680/CMD 80/40 16 NO YES NO VID80/CMD 80 24 YES YES NO C80X24/CMD 80 24 NO YES C80X24/ASM VID/CMD 80 24 YES YES NO D80/CMD 80/40 24 YES YES NO VID80X16/CMD 80 16 YES YES NO C80X16/CMD 80 16 NO YES NO ********** WARRANTY NOTICE ********** ALL SOFTWARE IS LICENSED ON AN AS-IS BASIS.
