- This is a *pre-release* BETA version of Scheme. It does *not* contain the code
- required to specify pin numbers, object types, part numbers, or
- "hidden" nets. Also, Saving, Auto-routing, and plotting are disabled.
- Since the Objects are not specified in detail, none of the checking functions
- are operative in the demo.
-
- This pre-release version is an example of what we are up to.
- If you have questions or suggestions, feel free to call or write us
- with them. Our address and phone are in the "info" menu selection
- in the sample program.
-
- Gadget tools are provided for:
-
- COPY
- DELETE
- MOVE
- ROTATE (90/180/270)
- FLIP (H/V)
- GROW
- SHRINK
- MAGNIFY
- REDUCE
- PAN (H/V)
- SPLIT A WIRE
- CHANGE PAGE
- MARK ALL
- UNMARK ALL
- FRAMEWORK LINE TYPE
- UNDO
- LAYER EDIT
- OBJECT/WIRE MODE SWITCH
- TEXT INSERTION
-
- The gadgets can be disabled by clicking the right mouse button while the
- pointer is over the gadgets. You can still operate, but operations can
- only be selected from the menus. Some operations are only available from
- the menus in any case.
-
- The object editor is functional, with the exception that
- specifying object electrical and physical parameters is disabled. The
- object editor can make new objects, or will edit current objects if they
- are selected when the editor is invoked by clicking the "grid" gadget.
- To use a "new" object, click in the workspace, then select "custom" from
- the objects menu.
-
- Scheme has a number of different modes. These are indicated by checkmarks
- in the menus, or the drawing in the gadget. These may get out of sync
- with each other in this version, but no problems occur because of this.
- The "op-amp" symbol indicates "global object-editing", the pencil (which
- appears next if the op-amp is clicked, is for text layer editing, and the
- drawing outline is for the framework (disabled in this version).
-
- Thge "hand" symbol indicates (in global object-edit) that you are in a
- mode that allows manipulation of the objects -- moves and so on. Click on
- this gadget, and a wire symbol appears. To wire, click the pointer over a connectable node
- on an object, and then again over another object. These wires will
- "rubber-band" when the objects are moved in any way.
-
- Multiple connections are permitted.
-
- Mostly, you will have to experiment with the system. If you need help,
- you can call us, and we'll try to, but we cannot spend too much time
- with each caller or we won't ever finish the project! So be considerate.
- We're working on it!
-
- Scheme should be released this summer, but may not actually appear until
- September, 1987. We want as many of the "bugs" out as we can manage so you
- don't get any "surprises".
-
- Thank you for your time in examining what SoftCircuits has to offer.
-
- Other products under development are in the areas of CAD (surprised?),
- Image processing, Amatuer Radio packet handling, and Amatuer Radio
- Slow Scan television, as well as some interesting items we can't tell
- you about yet.
