TRS-80 Model II Specifications:
Features for Today’s Needs … and Tomorrows Challenges
TRS-80 Model II is Radio Shack’s fastest and most powerful microcomputer. It is an extremely efficient business tool that can speed through routine tasks, store vast amounts of data, provide timely information for decisionmaking, and much more-at costs significantly below the industry’s “going price” for comparable computers. All this, yet it is easy to use!
Since introduction in mid 1979. Model II systems have brought the benefits of affordable data processing to businesses and professional people everywhere. Its remarkable combination of high power and low cost make it “just right” for countless applications. Even if you own a “maxi” computer, Model II can do many jobs that are “too hot” to wait for shared computer time and those too small for costeffective handling by your mainframe.
Radio Shack supports the Model II with a growing line of software and total before-and-after- the-sale service. Our inexpensive user-oriented, well-documented software includes programs for payroll, accounting, inventory control, mailing lists, with more to come. This allows your Model II to go to work quickly with no formal operator training. Model II features easy expandability, compatibilty with external equipment, communications and multi- language programming abilities, as well as low start-up and operating costs. We invite you to investigate the advantages of owning or leasing a TRS-80 Model II system. Why not arrange for a TRS-80 demonstration soon?
The Model II Hardware
he basic Model II is contained in one compact, desktop cabinet including a built-in 8″ disk drive for storing Progams and Data. A high-resolution 12″ video display, and a detachable keyboard designed to be similar to the familiar electric typewriter keyboard. It is simple to use. There are as few “special keys” as necessary to do the job. For faster and more accurate numeric input, a calculator-type keypad with . its own ENTER key is provided. Model II’s high-resolution video screen will display 24 lines of 80 upper and lower case characters. Optionally, double-width characters-40 per line-can be selected by your program.
Model II is available with either 32K or 64K of Random Access Memory (RAM). This means you can store 32,000 or 64,000 characters of information in the computer’s internal memory.
The disk drive provides 416,000 characters of storage for your programs and data on interchangeable “floppy” diskettes. If that’s not enough, just plug in a Model II Disk Expansion Unit with one, two or three more drives. Each added drive stores another 486,000 characters, bringing the total capacity of a four-drive system to about two-million characters. To fill this amount of memorv would require something like 96 hours of non-stop typing at 70 words per minute! Of course, a 32K Model II can be expanded to the full 64K of interhal memory at any time, via our 32K RAM Add-On option.
Tomorrow’s Microcomputer . . . Today
TRS-80 Model II is easily expanded to cope with growing or changing reqmrements. It won’t become obsolete in a few years. Connectors allow you to add printers, plotters, digitizers, communications with data-bases and other computers and a host of options. Internal plug-in card slots are also provided for later options. Model II includes a comprehensive reference manual and a diskette that contains the very powerful Model II Interpretive BASIC language and “TRSDOS” disk operating system. Additional programming languages are also available. withthem, a large number of specialized pre-written software packages in these languages can be used with your Model II, often with little or no modifications. These programs include COBOL, FORTRAN, Compiler BASIC and Editor assembler. Like all TRS-80 computers, Model II is U.L. listed. For value; versatility ease of use, and support, you can’t beat the Model II. It’s all business!
Model II BASIC- Our User-Oriented Programming Language
All of Model II’s operating software is loaded into Random-Access Memory from the system diskette every time you power-up the computer. So whatever language you choose, it leaves the maximum available user memory No addressable memorv s[ace is committed to Read-Only Memory (ROM). The Model II contains just a small amount of ROMthat merely loads the operating software, then is switched out.
TRS-80 Model II BASIC is an easy-to-use, expanded version of our Level II interpretive language. It's a 17K disk-based interpreter, and features detailed error flagging and quick editing that makes it especially easy to use for program development and debugging.
Model II BASIC is an enhanced version of our Level II language. So if you can program in Level II, you'll find Model II BASIC very familiar, and a bit more versatile and powerful.
A few of its outstanding features are -

    
  • Advanced string handling
        
  • Multidimensional arrays
        
  • Error trapping
        
  • Full editing capability for easy program corrections and changes
        
  • Program line renumbering
        
  • Hex and octal conversion Direct and sequential access to data in disk files
        
  • Ability to execute a TRSDOS command and return to BASIC with program and variables intact
        
  • Special functions to allow BASIC programs to call machine language subroutines
        
  • Recovery from operator errors - the System won't stop if you attempt output to a device which is not ready (such as Printer or Disk Drive)
    Command compatibility has heen maintained to the greatest possible extent for the convenience of Model I and III owners who decide to move up to the additional speed and capability of the Model II. And its language does offer quite an improvement for the machine language programmer.
    Model II BASIC is designed to run under our TRSDOS Disk Operating System and both are included with every new Model II
    TRSDOS - The Disk Operating System for Model II
    TRSDOS ("Triss-Doss") is a powerful and easy-to-use Disk Operating System that manages Model II's disk operations. It's a very comprehensive and powerful operating system for the programmer, yet it is virtually transparet to the non-programmer using pre-written software.
    TRSDOS occupes space on the System diskette. It's automatically loaded and ready for use after system power-on. however, only a small portion is actually in memory at any one time. The Supervisor Program, input/output drivers, and other essentials are always in memory. Auxillary code is loaded as needed into an "overlay area."
    Model II TRSDOS provides a full set of library commands and utility programs; and, in addition, many useful system routiens can be called directly by user programs.
    Some of the 37 Library Commands include: ATTRIB - changes a file's password. CREAT - preallocates data file space for added execution speed. COPY and MOVE -- allow files to be transferred. DEBUG -- lets you program, test, and isolate errors in machine language programs. DO - automatic power-up execution of a sequence of commands. FORMS - sets printer page length and width, line width, top of forms, and lets you toggle parallel or serial printer drivers. HELP - asists in clarifying TRSDOS command syntax. PATCH - modifies the code in our system's software so you can implement updates we provide. RENAME - change sthe name of a file. SPOOL - saves printer output in a disk file for later printing, and also allows printing at the same time other operations are being entered.
    The Utility Programs are: BACKUP - copes a diskette. FORMAT - organizes a diskette. MEMTEST - checks out RAM.
    In addition, you have a complete set of communications commands. ECHO - begins echo of keyboard input to display. HOST - allows keyboard input from and video output to a remote terminal. RECEIVE - inputs data into RAM from serial interface. SETCOM - sets RS-232 port paramters. TERMINAL - comprehensive and versatile menu-driven ASCII communications program.
    Machine language porgrammers can use Supervisor Calls which are Operating System routines. They can be used without worrying about hard address changes which could occur in later software releases. The routines alter certain System functions and conditions; provide file access; perform I/O to the keyboard, video display, and printer; plus perform various computations.
    TRSDOS also allows keyaheads of up to 80 characters. This means that through buffered storage, you can type in the next command while previous ones are being executed.
    Model II TRSDOS responds to your commands with positive feedback. If you say "KILL 'file-name,'" TRSDOS will responde with "'file-name' KILLED," or "'file-name' NOT FOUND," so you'll always know what was or was not accomplished by your command. And duplicating of a diskette requires knowledge of a master password, which give you additional program and data security.
    Plus, when an Operating System error occurs, a message appears on the video screen with a numbered error code. And if you don't remember the particular error, simply type "Error 66," for example, and Model II will respond with a detailed explanation.
    TRSDOS comes complete with your Model II. It includes a System Diskette in a deluxe binder, along with a comprehensive user's guide that documents everything you'll need to know.

    32K Memory Add-On 26‑4102 $449.00
    Model II Graphics Option 26‑4104 $499.00 Added Model II Versatility

    Now Radio Shack’s TRS-80 Model II Graphics Option with our new Graphics BASIC language lets you use your Model II’s video display screen as a “sketch pad” for the creation of whatever designs you may need. The result can be sophisticated tables, charts, graphs, illustrations, geometric patterns, maps and more.

    Hight Resolution.

    Your designs will be executed with fine detail, since the screen is composed of 153,600 picture elements, or “pixels”! That’s 640 points horizontally by 240 points vertically.

    Simple to Use

    Using the “paint styling” mode you can easily and rapidly fill in broad areas of the screen and you can use a variety of patterns. With the “line styling” mode, you have “point-to-point” graphics options that let you draw any line at any angle with just one BASIC statement!

    Easy to Learn

    If you already know TRS-80 Model II BASIC, Graphics BASIC will be a snal because you need to learn only eleven new commands! Their power is incredible. For example, by incorporating them into a BASIC program, you can create animation and motion!

    Summary of Graphics BASIC Commands:

    CIRCLE- Draws a circle, arc, or ellipse.

    CLS- Clears a character or display screen.

    GET- Reads the bit-pattern in a block on the display screen into an array for alteration and future use. Used in animation.

    LINE- Draws a line between points.

    PAINT- Paints an area in a specified style.

    POINT-Checks a point for being turned on or off.

    PRESET – Turns pixel on or off.

    PUT-Puts contents (bit pattern) of an array onto the screen. Altering these before they are put is part of creating animation.

    SCREEN – Screen Command/Flash mode. Useful in speeding up the display in painting and motion. Turns graphics screen on or off.

    VIEW- Defines the coordinates of a specified block (called the “viewport”) on the screen.

    VIEWPORT- Draws a viewport, which then becomes the current graphics screen.

    Installation Is Fast

    The Graphics BASIC memory board contains 32,000 characters of dedicated memory to store graphics data and is installed on the Model II in an unused slot. Includes user’s manual, 8″ diskette with Graphics BASIC, and subroutine library.

    64K Memory Expansion Board 26‑4105 $399.00 Gives your Model II the capacity to generate much larger workssets for the VisiCalc Enhanced program. This memory is not useable by other programs which do not employ special programming techniques required to access it. Installation required (not included).
    Hard Drive Units Now you can have immediate access to vast amounts of data-almost 9 million characters! With the Radio Shack Hard Disk System, you can set up a powerful data base management system. And you can expand with up to three “secondary” Hard Disk Drives for a total storage capacity of over 33 megabytes. Best of all, most Model II and Model 16 programs will transfer directly to hard disk.

    The TRS-80 Hard Disk System is comprised of two 8″ platters, permanently sealed in a dust-free environment. Both surfaces of each platter are accessed by their own read/write head – forming a cylinder of four tracks under the head at any one time. Winchester technology provides reliable, high-speed data transfer. All current TRSDOS library commands are available, plus two new utilities: SAVE and RESTORE. The SAV utility quickly and efficiently saves data from the Hard Disk onto one or more back-up diskettes. You can save all data, a defined list of data, specific file names, or files that have been created or updated since a particular date. RESTORE reads the data on the diskette and writes it back onto the Hard Disk. To best utilize the Hard Disk System, the Global Search sequence on Models II and 16 will examine the hard disks first, then the floppy disks. Expand the storage capability of your Model II or Model 16 with our incredible Hard Disk System. Installation required.

Your Model II will be just like a Model 16, but using your existing disk drive, and having a maximum of 256K internal memory.

    Compatible With Model II Software!

    Your system is still a “full-function” Model II, and you can use all of your present Model II software without modification. You may also use the software Radio Shack is developing to take advantage of the MC68000′s 16-bit processing power.

    Dual-Processor Architecture

    With the Enhancement Option your Model II will actually contain two microprocessors because the Z-80A processor and its support circuits are retained for Input/Output. This frees the 16-bit procesor to bring its full powert to bear upon data processing problems and memory management functions.

    Multi-User Capability

    By mid-1982, your enhanced Model II, operating as a Model 16, will be able to support three users simultaneously! Thus two workstations in your office can be low-cost remote terminals like our new DT-1′s. It’s like having three computers in your office at a much lower price!

    How Arcnet Can Work for You.

    Let’s say you’re maintaining customer, sales and inventory records on a TRS-80 computer with printer and hard disk, and several sakes or managerial people need fast access to up-to-the-minute status. Up to 255 TRS-80′s can be tied into an Arcnet system to utilize the same disk files and even the same printer. But in addition to sharing files, each user now has the benefit of his or her own computer system (including space on the hard disk for files), so other functions can be performed-electronic filing, word processing and so on. And all files on the hard disk me available to any user. Confidential files can, of course, be restricted.

    Easy-Growth System.

    In this Arcnet system, you can increase your processing ability significantly without the cost of printers or hard disks for each additional user – and without any reprogramming. You can continue adding TRS-80s to the network in affordable steps – and with out downtime – to meet the needs of your growing business. This system could easily tie into an administrative office word processing system where five workstations are sharing the resources of two printers. Your entire company now has a common database accessible to all users!

    Expand to the Power You Need.

    The smallest practical Arcnet system consists of three computers. Two workstations – called applications processors – can be connected to share the large hard disk file of the third TRS-80 – known as a file processor. As you exceed the capacity of this three-computer network simply plug in another applications or file procesor.

    Installation Is Simple.

    Arcnet consists of three hardware components. First, the Arcnet board is needed in each computer – it installs in an existing card slot in the rear of the TRS-80 Model 12. When using a Model II, you will also need a 16K Z-80 Memory Expansion Board if the Model II has not been used with a hard disk. The second element is the Coaxial Cable. One end is plugged into the computer, the other end goes to the third component, the “Hub”.

    Arcnet File Processor Software 26-6502 $499.00 Includes software, operation manual and system manager’s manual. Only one package required per system.
    16KB Z-80 Memory Expansion Board 26-4503 $189.00 For Model II previously not used with hard disk.
    Passive Hub 26-4504 $79.00 Connects up to three Applications Processors to one File Processor. Cable length between Applications and File Processors can extend up to 20 feet. (Two passive hubs cannot be connected in series)

    The entire TRS-XENIX development system includes all standard UNIX utilities (about 250 modules) for multi-user software development, including:

    C language compiler

    assembler

    text editor

    text processing (not including editors)

    text print formatting

    typesetting

    spelling dictionary with over 20,000 words

    accounting and invoicing system users

    electronic mail

    relocating program loader

    maintain program groups

    print spooler

    sort utility

    stream editor

    command processing

    BASIC language interpreter

    FORTRAN compiler (compatible with C)

    structured FORTRAN preprocessor

    compiler generators

    file management

    pattern recognition and file comparison

    pattern scanning and processing language

    interactive program debugger

    full password protection

    on-line communications

    system status information

    system maintenance

    on-line UNlX programmer’s manual

    TRS-XENIX development system is for program development only and is not needed to run applications or other languages. It requires a minimum of 256K memory (512K is recommended) and a hard disk drive.

      Just happened on this site and this brings back memories. Back when I opened my accounting office I had a II with 3 disk bay with the 3 disc ledger, Multiplan and Scripsit plus Westlaw. At the time is another firm had a computer it was usually a PDP-11 or an IBM Systems 3. A few years later I went to law school and added a Model 100 with a disc drive and took notes, did papers and homework on it and then downloaded it to the II for final format and printing. The 100 was the 1st computer any student had ever brought on campus and it had to go to a committee to get permission to use it.

      On opening my law office, I upgraded to a 16 with 3 HDs and Xenix with their chain printer and 5 Wyse 100 terminals, one in each office. I added Precedent that was the first and for some years only true law office integrated system and Profile Plus plus converted the existing programs to Xenix versions. The system ran 24/7 for some years until long after RS stopped selling them and notified me they would not longer support repairs. I switched to SCO Xenix and a 80286 based server as it was supported by Precedent and West and though I could switch to other apps, these were key and core to the office. Scripsit was switched to Lyrix as RS never delivered the Scripsit for the 3000 Xenix that would have worked with the setup and discontinued Multiplan in favor of Visicalc so I went to SCO Professional.

      The 16 went to my desk and I used it as a standalone computer and also had it hooked to the office system. It continued to run with not downtime 24/7 until I retired. The 80286 during that time went through a HD so the 16 proved more reliable.

      As a result of Xenix and TRS-DOS I missed the MS/IBM DOS and 3.x days and my first experience was with Win95. In ’92 I bought a new mag with an operating system named Linux and scratched my head. Today, it is amazing to see how far is has come, the total loss of Xenix and the near loss of UNIX as well as the implosion of SCO and MS-Xenix and MS-UNIX. Today if I did not have to have specific apps requiring Windows, I’d be using Linux.

      From time to time I still think foundly about the II, 16 and 100 computers and just how great they were. Perfect, well noting is perfect but back then they were as close as you could get to a computer given the technology during their development. I could easily still use them for almost all of my computer work other than the tax apps I have to have. In fact Precedent is still as in spec as any law office program today out there unless you start considering hang ons such as Outlook.

      Thank you for the memories.

      I have a TRS-80 Model II I would like to sell. Any ideas who might want to purchase it?

      I have about a half dozen 8 inch floppy discs I’d like to get the data from. I no longer have an 8inch floppy drive device.

      The discs were recorded in 1981 on a TRS-80. The floppies are Single Sided, Double Density (SS, DD) record length 128 bytes.
      Memorex and Maxell branding. The discs have been carefully stored in their jackets and I have no reason to believe they
      have any issues.

      I’d appreciate anyone’s input on how I might get these floppy disks read and the data transfered to CD. I have a copy of VISICALC which runs on my PC so I can access the files once they are readable on a hard disk.

      Thanks for your assistance with this inquiry……………all the best………….Kernel

      I started exploring computers as a kid in 1979 at Radio Shack. I had read a book that covered some aspects of BASIC programming, and I used to enjoy keying in programs and running them on the Radio Shack micros. The Model II seemed impressive to me because it looked more sophisticated than the Model I, and the text on the screen looked more clean and crisp, and I thought it was cool that it had mixed-case text because I had only seen a Model I without the lowercase mod.

      It’s amazing that back in the day, those expensive floppy and hard drives seemed like a lot of storage, but with 4 hard drives you could only get about 30 or 40 meg. There was no audio, images, or video, so about all you could do is have a huge mailing list or some sort of database.

      Just think… you could buy 4 hard disks for over $10,000 and store about 9 or 10 songs in MP3 format on them!

    5. hi, I want to buy a computer TRS-80 model II.
