- Hello!!
-
- Welcome to SchematicMaster. This program is the result
- of hundreds of hours of work. It was written specifically to
- handle documentation and to clear up a whole file cabinet of
- napkins and old envelopes with scribbled schematics on them.
- This is sort of a early beta version on which we would
- like to get comments and suggestions before finalizing version
- 2.0. I have found it very useful but it does have some problems.
- It is written entirely in assembly language for speed and versitility.
- If you would like to receive a larger IC library and a printed
- manual and reduced price on version 2.0 just send us $15.00 and
- we'll send a new disk right out.
-
- For a good set of comments you might get it for nothing.
-
- There is space for 1000 ICs in the main library. Only
- the most popular of the 4000 series are included in this
- program. A large library of over 200 ICs including the most
- popular of the 74 and linear series will be sent to you after
- you send us the $15 fee to register your ownership. Other
- libraries will become available and specialized libraries may
- be custom-ordered.
-
- FOR THE RECORD:
- This program is being distributed as shareware and the
- usual rules apply. You can make as many copies as you like for
- friends etc. as long as they are complete and unmodified and
- you do not charge for them. Public Domaine distributors should
- contact us for authorization.
-

- INTRODUCTION
-
-
- SchematicMaster is a CAD schematic drafting program. It
- is the ideal way to turn jotted notes into a professionally
- finished drawing with a minimum amount of time and effort.
-
- It is assumed that the user will have general computer
- literacy though all instructions are complete and
- comprehensive.
-
- SchematicMaster is designed to run on IBM PC or
- compatible with 256K memory and MSDOS 2.1 or higher. It
- requires color graphics capabilities and is compatible with
- standard graphics printers.
-
- Standard size sheet on which schematics are drawn is 2x3
- screens. This allows 3 schematics to be stored on a standard
- diskette.
-
- Most commands are are single key or menu driven. This
- allows immediate use without learning a new instruction set.
-
-
-
-
-
- The Integrated Circuit Library contains most 4 to 40 pin
- ICs in current use. There is additional space for 32 user-
- defined ICs.
-
- Program is usable with single disk drive but dual disk
- drive will be much more convenient. Prompts will vary due to
- number of drives in system.

-
- INSTRUCTIONS
-
-
- All files on disk other than template files are an integral
- part of program.
- DO NOT ERASE OR RENAME!!
-
-
- BACK-UP COPY
-
- A back-up copy is advised and can be made using standard
- DOS diskcopy function.
-
-
- PREPARING PROGRAM DISK
-
- With DOS booted and DOS disk in drive, type:
- SYS B:
-
- Following prompts, put Schematic program disk in drive,
- Enter. Continue following prompts.
-
- After system has been installed, copy your DOS COMMAND.C OM onto SchematicMaster disk.
-
- When completed, it would be advisable to place write-
- protect tabs on the original disk and the backup copy. Then
- make a working copy (with system files).
-
- Use Control/Alt/Delete to reboot program disk.
-
-
- KEY TEMPLATES
-
- Included are function key templates for IBM 83-key
- keyboard and the Keytronics deluxe extended keyboard. They
- can be cut out and taped onto the appropriate keyboard.
-

-
-
- FILE NAMES
-
- Use drive specifier for document disk when asked for
- filename. All DOS file naming conventions apply. (e.g.
- [D][PATH] FILENAME [.EXT]
-
-
- DOCUMENT DISK
-
- The schematics you draw will be stored on the Document
- Disk. To create the Document Disk, format a blank disk
- without specifying system files (do not use /S). Up to 3
-
-
-
-
- standard schematics can be stored on a Document Disk.
-
-
- START UP
-
- To begin operations, Type:
-
- SCHEM
-
- Prompts will appear appropriate to the number of disk
- drives. In a multi-drive system it will be assumed that after
- the document disk is installed it will remain in the same
- drive.
-
- The program is divided into three catagories:
-
- 1. Drawing and Documentation
-
- 2. Component Placement and Editing
-
- 3. IC Placement and Editing

-
- SAVE
-
- It is possible to save at any time while in DRAW mode by
- pressing F5.
-
-
- DRAWING MODE
-
- When white screen appears it shows the upper left hand
- corner of drawing sheet.
- ________________
- | XX | | |
- |----|----|----|
- |____|____|____|
-
-
- To scroll up, down or across the sheet use Alt with
- cursor keys. Home brings screen to upper left corner of
- sheet. End moves screen to lower right corner of sheet.
-
-
- CURSORS
-
- The red ERASE cursor (F3) will be in the center of the
- screen.
-
- This can be changed to the black DRAW cursor by using
- F2.
-
- F1 will get the blue MOVE cursor.
-
- All cursors are moved with the standard cursor keys
- (with NUM Lock off).
-
- A few minutes of experimentation will familiarize you
- with these functions. Notice that the cursor moves quite
-
-
-
-
- quickly and that it may be difficult to line it up with a
- previously drawn line or a specific point.
-
- Page 4
- * * * * * * * * * * * * *
-
-
- F4 will get a slow moving, expanded, blinking cross-hair
- cursor which will make horizontal and vertical alignment
- quite simple. F4 is an on/off toggle function.
-
-
- CONNECT
-
- The convention of placing a dot at point where 2 wires
- connect is supported by moving the cursor to intersection and
- pressing F9.
-
-
- LABELS AND CHARACTERS
-
- While in MOVE mode all standard characters can be typed
- and will appear directly to the left of the cursor. This
- allows labelling of components and values. Shifted
- characters are overlined to give the "Not" function.
-
- CLEAR SHEET
-
- If you are unhappy with the format you are using and
- wish to start over, retaining the same document name and
- specs, use Alt F1 to Clear Sheet. This clears the entire 6
- screen sheet.
-
- BE CAREFUL!! There is NO reuse buffer!
-
-
- BLOCK ERASE
-
- The Block Erase Function can be used to erase large
- areas of schematic but it can only be used on the visible
- screen. By using the Block Erase you will rarely need to
- Clear Sheet.
-
-

-
-
- BLOCK ERASE (cont.)
-
- If you should make an error in placing a component and
- wish to erase it, move the cursor to one corner of an
- imaginary rectangle around the component you wish to erase.
- Press Alt F3 to mark the corner with a red dot. Then move the
- cursor to the diagonal corner of the area you wish to erase.
- Mark this corner with Alt F3. A red box will be drawn around
- the area and you will be asked if this is what you wish to
- erase. Press yes to erase everything within the box.
-
-
- COMPONENT UTILITIES
-
-
-
-
-
- When a component (e.g. diode, resistor, transistor etc)
- is required, use F7. Menu will pull down from top of screen.
-
- While in component utilities, ESC will return to top
- level menu, ESC again will return to DRAWING mode.
-
- To make use of a predefined component from library -
- press 1 (Get A Component.) When asked for name of component
- refer to list supplied for name. To show list of component
- names currently stored, press 4.
-
- The component can be rotated to all four orientations
- using the space bar. The component will then be shown and
- can be moved with cursor keys to desired location. The
- backspace key will give a mirror image of the component. When
- component is properly placed (be sure of this) hit Enter to
- release cursor and lock component in place.
-

-
-
- MAKE A COMPONENT
-
- If the component you desire is not on the list, press 3
- (Make A Component).
-
- You will be asked name of the component (up to 8
- characters). Component grid will appear. Proceed to draw
- character using cursor keys to move cursor and space bar to
- toggle pixels in component on and off.
-
- The component is drawn white on black. To right of
- grid, component will be shown in actual schematic size.
-
- If you wish to change design or name of any component an
- edit feature is supported.
-
-
- IC UTILITIES
-
- IC Utilities are accessed by Alt-F7 (as opposed to F7
- for Components). Menu appears at top of screen and is self-
- explanatory.
-
- If IC requested is not in library you can easily add the
- one you need by following instructions on menu. This is
- similar to adding a component.
-
- Should you need to add more than 32 extra ICs to
- library, it will be necessary to use the back-up copy to
- create a new working copy with empty add-on library. Keep a
- record of which ICs you add to which working copy to aid in
- selecting working disk to be used.

-
- PRINT
-
-
-
-
-
- To print at any time during Draw Mode press Alt F2.
- This will print the entire 6 screen sheet sideways on the
- paper. The entire schematic will fit on a legal size sheet (8
- 1/2 x 14). To use a standard sheet (8 1/2 x 11) do not draw
- on far right hand 1/6 of sheet (1/2 of far right hand screens
- both top and bottom).
-
-
- MOUSE INSTRUCTIONS
-
- It is possible to use a mouse with SchematicMaster.
- Generally use of the cursor keys will be found to be easier
- and more precise but for some applications use of the mouse
- may be preferred.
-
- To make use of the mouse, the Mouse Device Driver must
- be copied onto the SchematicMaster disk. DEVICE = MOUSE.SYS
- must be included in the CONFIG.SYS file. Please check your
- mouse handbook for further information.
-
- In operation the cursor will follow the movement of the
- mouse. The left-hand button will cycle through the cursors as
- follows: DRAW, MOVE, ERASE, MOVE, DRAW, etc. The right-hand
- button will slow the cursor and display the crosshairs while
- it is held down.

- GENERAL HINTS FOR DRAWING SCHEMATICS
-
-
- Schematics are generally drawn with inputs predominantly
- on the lefthand side and outputs on the righthand side.
-
- Positive supply voltage bussing is usually not shown
- except for very close connections. It is completed with an
- arrow pointing upwards with voltage value at the top.
-
- Ground connections are generally shown by a triangle
- pointing downwards. If there is more than one kind of ground
- (e.g. logic, power, analog) this is specified by using a
- letter inside the triangle.
-
- IC type numbers are usually not shown at the IC. Instead
- the ICs are assigned a letter and sequential number, such as
- A1, A2, A3, etc. A chart relating assigned number to type
- number is placed in the lower right hand corner of the sheet.
-
- The lower right hand corner of the sheet is used for
- general notes and also for assigning a standard value to
- components (e.g. Unless otherwise speci-fied, all resistor
- values are 1/4 watt.).
-
- Readability and ease of drafting can be greatly improved
- by carefully consider-ing placement of ICs before beginning
- especially on complicated schematics.
-
- ICs should be placed before other components. Be sure to
- allow sufficient space for interconnection.
