Gary Weber Ultrascreen100 is hereby made available to the masses! Starblaze100 is here for your enjoyment!
CLOCK2
USC100.zip Ultrascreen100 was the most significant display enhancement ever to come along for the Model 100. It switches your display into a smaller font and gives you 60 columns by 10 lines. That's 600 characters you get on the screen at one time, versus the standard 320. Even more, the Ultrascreen100 software was *very* smoothly integrated with the machine. The Main menu is always in the standard 40x8 mode, but when you jump into BASIC, TEXT, or TELCOM, you automatically switch into the 60x10 mode. Compared to Travelling Software's View80, which only gives you a 60x8 screen and requires activation through an extra step in their ROM software, Ultrascreen100 was clearly the better choice. Ultrascreen100 originally was sold by Ultrasoft Innovations back in 1986. As of November 23, 2007, it has been released to the public for free-distribution. Many thanks to Daniel Born (author) and Richard Eckerlin (Ultrasoft) for allowing this to become a reality!
TXTADD.BA When in TEXT, you may find that you get sluggish text-entry performance with Ultrascreen active. A lot of times you might simply want to jot down your thoughts rapidly and having sluggish keyboard interaction can be quite distracting. This utility I've created does not do full-screen editing, but it does allow rapid appending of text to a .DO file and it makes use of Ultrascreen's 60x10 mode. [Updated 11/25/2007]
TXTADD.DO This is a non-tokenized pure ASCII version of TXTADD.BA.
STAR16.CO This is the binary version of STAR16. Don't bother with STAR16.DO if you already have the means of loading this directly into your M100s memory from Desklink, TPDD, or NADSBox via TS-DOS or some other DOS capable of binary file loading.
STAR16.DO BASIC loader for STAR16.CO. **UNTESTED** This file is gigantic. It would need to reside in your M100s memory only in tokenized .BA form (delete the .DO file before running!) and even then, you'll need to run it, then DELETE the .BA (or type NEW if it is only in the temporary space), and *THEN* type the 'SAVEM "STAR16.CO", 58048, 62930, 58048' command.
CLOCK2v1.1.zip CLOCK2 v1.1 for the TRS-80 Model 100, Tandy 102, and NEC PC-8201A/8300. What started as just an NEC conversion of Club100's CLOCK2.BA for the M100 has turned into a new release for all platforms. Everything in this ZIP file is also present in the CLOCK2 folder, for viewing and downloading of the individual pieces.
ASTRO.BA BASIC loader for ASTRO.CO. This will show you the instructions for the game, and then load ASTRO.CO into memory using device "0:", which TS-DOS "DOS-ON" feature provides. If you have a different DOS that uses a different device name, you'll have to change line 50 as appropriate.
ASTRO.CO "Asteroids" style game for the TRS-80 Model 100 and Tandy 102. This was originally provided with the Booster Pak on rom, but it has now been extracted and made available to anyone who has a modern ROM-based disk operating system like TS-DOS. This requires the BASIC loader. It cannot exist as a .CO file in the M100's file system! It *must* be loaded using your DOS directly into high RAM, which is what ASTRO.BA does.
ASTRO.DO This is a non-tokenized pure ASCII version of ASTRO.BA.
BP1ROM_Fixed.bin This is the Booster Pak v1.23 "BP1" main system ROM image which includes the multi-page file display bug fix. With the original ROM, if you have more than two pages of files to display, you would only ever be able to see the second page of files when pressing shift-down. The third page of files or beyond was inaccessible due to a limitation in Traveling Software's TPDD client. Well, with this replacement BP1 system ROM image, the limitation is gone! The bug fix was originally made available in Ken Pettit's release of the TS-DOS 4.10 option ROM. This fix has been extended to all RAM versions of TS-DOS, as well as the SARDOS option ROM. And now, it is available for the "Disk" client that is in your Booster Pak's system ROM. Just burn this image to a standard 27C256 EPROM and replace your Booster Pak's "BP1" chip which would be all the way on the bottom-right side of your Booster Pak's sockets.

Robert Pigford Programs for the Model M100/T102 and T200 that help enhance our experiences.
TOKENIZE
Number Conversion
VBASIC
VBASIC.BA VBASIC.BA (in tokenized BASIC format, not .DO format). While once available on the Club100 BBS, here it is again. This great program by Dr. William T. Verts is called VBASIC. Line numbers are no longer needed when writing your BASIC programs. VBASIC.BA translates the text form of a program that you created with a word processor (like TEXT). Line numbers are not needed. The resulting "translated" file is in .DO format file and subsequently can be LOADed into BASIC and run (and/or SAVEd). PLEASE see the March 1990 issue of Portable 100 Magazine on Club100.org for all the details. Edit line #1200 for compatibility with your model of ModelT (use 63032 for the M100/T102 series, or 61189 for the T200).
VBASIC.EXE Dr. William T. Verts also created and made available on the old Club100 BBS a version of his VBASIC called VBASIC.EXE. This is the same as VBASIC.BA but created in an executable form to run on a DOS computer. VBASIC.EXE will translate your un-numbered text program files and produce the same line numbered text file suitable for LOADing into BASIC that VBASIC.BA would. As an executable file, it is much faster on a DOS machine than VBASIC.BA on the ModelT. Note: It seems to run in a DOS window under Windows XP just fine. Remember to have your source file in the same directory as VBASIC.EXE. Interestingly, VBASIC.EXE can also be used to create a translated file for use with GWBASIC (for DOS) which also requires line numbers. Use GWBASIC commands and syntax in your text file, run VBASIC.EXE on it, and you will create a line numbered text file that can be LOADed into GWBASIC and run, etc. See the March 1990 issue of Portable 100 Magazine available on Club100.org for all the details of VBASIC usage.

UR_Support_Files
trk100.do Satellite tracking program for M100. (Requires keplrn.do) My modified version with Y2K Fix and with the tracking interface and the kep update routines removed is in this archive. Original TRK100 software can be downloaded here: ftp://ftp.amsat.org/amsat/software/model100 *Installation Instructions:* 1. Download TRK100.DO and KEPLRN.DO if you haven't already. 2. Connect your M100 to your PC with a Null Modem Cable. 3. On the M100 launch TELCOM and setup your com port. * I usually set my COM port to 1200 baud 8N1 with XON/XOFF. To do this issue the STAT 58N1E command at the Telecom: prompt. 4. After setting your baud rate and flow control above enter TERM. 5. Launch your favorite terminal program on your PC and configure the baud and flow control paramaters to match that of the M100. If using the above 58N1E insure that Software Flow Contorl is enabled. 6. Transfer via ASCII the two files listed above. * Hit F2 on the M100
keplrn.do Keplerian elements for tracking sats with trk100. See http://niedobry.freeshell.org/mod100/ for most recent.

Sunup.do SUNUP.BA reports sunset and sunrise times and solar azimuths at any Earth location for any date. It first prompts for the Latitude/Longitude coordinates of a place on Earth. Express coordinates in degrees as fractional numbers using: positive values for North latitudes and East longitudes, and negative values for South latitudes and West longitudes. For example, input "-37.81666667, 144.9666667" for the location of the city of Melbourne, Australia (i.e., South 37°49'0", by East 144°58'0"). It next prompts for a time zone for time results. Express this as a quantity of time zones situated West of Greenwich, England. For example, input "0" for the Greenwich Mean Time zone (i.e., time results in UTC). Lastly, it prompts you to elect a date using the format: numeric year, numeric month, numeric day. You may elect any past date, the current date, or any future date. For example, input "2012, 12, 21" for the date of December 21, 2012. The program then reports the time and solar azimuth of sunset and sunrise.
Vp6dx.do As-is, VP6DX.BA has short-term value to Radio Amateurs who desire contact with DXpedition operators of station VP6DX while it's on-air at Ducie Island. Ducie Island is a South Pacific atoll that's located at South 24°40'52.6" by West 124°47'11.0". The program reports the sunset time in UTC and sunrise time in UTC at Ducie Island (and solar azimuths) for the current date. It senses the DATE$ function of the laptop in order to ascertain the current date. Because times are reported in UTC (i.e., the Greenwich Mean Time zone) and the TIME$ function influences the change of date occurrence in the DATE$ function, accurate reports result only where you have set TIME$ and DATE$ of the laptop so that they express the UTC time and the UTC date. However for Grayline propagation prediction purposes, sufficiently accurate reports are obtained where the DATE$ of the laptop differs from the UTC date by less than 2 days. Note that VP6DX.BA is a special purpose variant of SUNUP.BA which also is available (file SUNUP.DO).
Plan 1c Beam Azimuths from Field Day 2009 Site.tif Azimuthal equidistance projection map centered on a 1320-foot elevation Field Day 2009 site. It shows the radio coverage by the two selectable major lobes of a 2-element echelon array (a coparallel array, end-fire antenna) as two color coded areas of ±27.5° beamwidth: blue&green along bidirectional 280°==100° heading, and red&orange along bidirectional 225°==045° heading.
Ft5ga.do As-is, FT5GA.BA has short-term value to Radio Amateurs who desire contact with DXpedition operators of station FT5GA while it's on-air at Glorioso Islands. Glorioso Islands are in the Indian ocean located at South 11°30'00" by East 47°19'48". The program reports the sunset time in UTC and sunrise time in UTC at Glorioso Islands (and solar azimuths) for the current date. It senses the DATE$ function of the laptop in order to ascertain the current date. Because times are reported in UTC (i.e., the Greenwich Mean Time zone) and the TIME$ function influences the change of date occurrence in the DATE$ function, accurate reports result only where you have set TIME$ and DATE$ of the laptop so that they express the UTC time and the UTC date. However for Grayline propagation prediction purposes, sufficiently accurate reports are obtained where the DATE$ of the laptop differs from the UTC date by less than 2 days. Note that FT5GA.BA is a special purpose variant of SUNUP.BA which also is available (file SUNUP.DO).
Dx0dx.do As-is, DX0DX.BA has short-term value to Radio Amateurs who desire contact with DXpedition operators of station DX0DX while it's on-air at Thitu Island. Thitu Island is in the Pacific ocean located at North 11° 03' 05.4" by East 114° 17' 02.0". The program reports the sunset time in UTC and sunrise time in UTC at Thitu Island (and solar azimuths) for the current date. It senses the DATE$ function of the laptop in order to ascertain the current date. Because times are reported in UTC (i.e., the Greenwich Mean Time zone) and the TIME$ function influences the change of date occurrence in the DATE$ function, accurate reports result only where you have set TIME$ and DATE$ of the laptop so that they express the UTC time and the UTC date. However for Grayline propagation prediction purposes, sufficiently accurate reports are obtained where the DATE$ of the laptop differs from the UTC date by less than 2 days. Note that DX0DX.BA is a special purpose variant of SUNUP.BA which also is available (file SUNUP.DO).
JD_MJD.DO JD MJD.BA converts the Gregorian date that the Model T laptop (M10x or M200) holds in its calendar to the corresponding Julian Day (JD) and Modified Julian Day (MJD). It is valid for Gregorian dates from January 1, 2000 (i.e., DATE$ of 01/01/00) through December 31, 2099 (i.e., DATE$ of 12/31/99). The simplified mathematics of this program is made possible by using a baseline JD of 1721119.5 (see commentary of line 5), which corresponds to the Gregorian date of March 3 in the year 1 Before Common Era (BCE) at midnight Universal Time Coordinated (UTC). Note that the MJD is a 5-digit shortened variant of the JD. You may use the 5 numerals of the MJD as the trailing 5 characters in a filename to designate its date. For example, file J56116.DO is a journal file for the Gregorian date of July 8, 2012.
SECTNS.DO This is a list of 83 section abbreviations that are in effect for the November Sweepstakes of 2012. There are 71 sections of the American Radio Relay League (ARRL); there are 12 sections of the Radio Amateurs of Canada (RAC). A section abbreviation is either 2-letter or 3-letter. With the cursor positioned at the beginning of file SECTNS.DO, press the F1 key (Find) and then enter a section abbreviation followed by 1 Space character in order to determine the validity of a section abbreviation. For example, pressing F1 and entering "SJV " confirms that SJV is a valid section abbreviation and that it stands for the "San Joaquin Valley" section.

Feedback welcome. If I've screwed something up, I'd sure appreciate hearing the correct info. Thanks. -- Mike Nugent 04/05/17

TRNSFR.BA TRNSFR.BA allows you to transfer a .DO file from one Model T to another via a null-modem serial cable. This program has the advantage of transferring at 19200 baud, which means it takes seconds to transfer anything. The contents of the file are not displayed on screen. The disadvantage is that if a paragraph is greater than 256 bytes, it will put a paragraph mark in the middle of the paragraph. If anyone knows of a fix to this, please e-mail me at djjsak(at)gmail.com.
JERNAL.BA This is the program I use to insert the day of the week, date, and time in my jernal. It uses the format: Tuesday November 22, 2005 08:32:35 PM When you first run it, it creates a file named using the first three letters of the month, a dash, then the year. Sample: NOV-05.DO
NOMENU.DO This explains how to prevent the Model T from exiting to the menu when you have to shut it down in the middle of a document.

DIGICS.TXT PC text file - DIGItizing the Character Set - the 'big' file, converted for PC use. View in Notepad with Terminal font.
KEYMAP.DO BASIC file - KEYboard MAP - displays your keyboard with GRaPH and other special key-combinations. Made on a 102.
PI.DO BASIC file - PI or 3,14159... - 2 ways to calculate PI and a way to display it when you have the older character set for the model 100, that can't.
C2.DO According to me, the most user-friendly display of the entire character set of your model T. Works on 100, 102, 200, M-10 and Virtual T. Just 1 (long) line of BASIC.
