Tinkering With TDOS
by James Poulin

Tinkering With TDOS Part 1 Introduction I have been asked to write a series of articles to familiarize our readers with the T-DOS operating system. During the course of these articles, I will use passages directly from the T-DOS documentation files. This is done because I feel that the existing documentation explains technical matters better than I might be able to.

Tinkering With TDOS Part 2 Introduction Last month we learned what T-DOS is and worked through an sample installation. T-DOS can be installed for many hardware configurations and has many options for you to choose from. The installation example was set up for a TV type monitor but T-DOS is capable of driving an 80 column display as well. There are a few differences when installing 80 column T-DOS, one of the most notable differences is that you run the 80TDOS45.COM program. When you get to the I/OBYTE setting, you select CON=UC1. If you are using an EVE VD-MB, you answer YES to that question. This will set the correct comm port for the video output. There are no color selections for the 80 column display.

Tinkering With TDOS Part 3 Introduction This month we'll continue with the discussion of the T-DOS Resident Commands. As you can see from the examples, the commands are versatile and powerful. The command structure is nearly identical to those in DOS (IBM and compatibles). This makes it easy to work back and forth between my machine at work and ADAM at home.

Tinkering With TDOS Part 4 Introduction Last month I finished up with the Resident Commands but before I go on there is one addition I would like to make. Commands can be chained or linked together in such a way as to execute multiple commands on one command line. The following is an example:

Tinkering With TDOS Part 5 Introduction Last month I began a brief explanation of the T-DOS utility files. I'll go over the remaining files and begin a more in-depth explanation of the most useful files. But first, I would like to thank Ron Collins for providing his technical support in the preparation of these articles.The remaining files are: MOUNT11.COM MOUNT11.COM was written to allow folks with LARGE hard drives to partition into say.. 5 or 6 logical drives. Then, using T-DOS as if the hard disk had only 4 logical partitions, it would allow you to substitute one of the drive areas in the position of another. For instance,

Tinkering With TDOS Part 6 I want to thank our MOAUG newsletter editor and resident POWERPAINT EXPERT Pat Herrington for designing the new column header for me. She has used some newly created fonts that will be available soon from IZOD Graphics. Pat has been working hard to complete this next addition to her long list of POWERPAINT support products. I'm not sure why she chose TINKERING with TDOS as a title, maybe she is trying to tell me something.

Tinkering With TDOS Part 7 .OP The last of Rob Friedman's free disks is MODEM.GIV. The following is a list of files included in the package: 1. -Readme.1st - This Information File 2. Crunch.Com - a file compressor using the LZW algorithm 3. Crlzh11.Com - a file compressor using the LZHUF algorithm. Usually makes smaller files than Crunch 4. Dirchk.Com - a breakdown of the blocks assigned to the various files...

Tinkering With TDOS Part 8 LONG & LOUD consists of two programs that allow you to use your dot matrix printer in the Sideways mode. The object of this discussion is LONG, it prints any ASCII file in the sideways array, this file can come from a spreadsheet, a database, a word processor, or any program that has the capability to output an ASCII file (Note: ADAMCalc does not have this ability).

Tinkering With TDOS Part 9 Clip Art Conversion This month I have gotten off onto one of those tangents that we so often find ourselves involved in. True, it is not fully T-DOS related, but T-DOS does play an important role in the overall operation. Last year at ADAMCON 2 in Toronto I witnessed a demonstration of Clip Art Viewer by Walters Software. The software was purchased and sat on my computer desk until about a month ago. I decided to try to convert some clips from Print Master Plus, a graphics program in DOS that makes cards, signs and posters. The following is an account of how I did it and a list of problems that I encountered during the operation.
