LISA MRD/PRD AMENDMENTS
I. ADDITIONAL LISA MRDS
Some areas covered in the MRD will adhere to the direction stated
but will be subject to change until detailed, separate MRDs are
prepared for each one. These areas, and the target completion
date for each, are as follows:
1. USER INTERFACE May 31, 1980
2. SOFTWARE THEFT PROTECTION May 31, 1980
3. USER SET-UP AND CUSTOMIZING June 30, 1980
4. TERMINAL EMULATION June 30, 1980
5. VISICABINET June 30, 1980
6. WORD PROCESSOR June 30, 1980
7. GRAPHICS EDITOR June 30, 1980
8. PERSONAL APPLICATIONS June 30, 1980
9. MASS STORAGE PERIPHERALS June 30, 1980
10. PRINTERS June 30, 1980
11. NETWORKING AND ELECTRONIC MAIL July 31, 1980
12. DIAGNOSTICS/TESTING July 31, 1980
13. BUSINESS GRAPHICS July 31, 1980
14. INTRODUCTORY INTERACTIVE MANUAL August 31, 1980
15. 'OEM PRODUCTS (DEVELOPMENT TOOLS) August 31, 1980
II. HARDWARE ENGINEERING AMENDMENTS
1. Both Alps and Keyboard Co. (bucket) keyswitches will be
pursued as potential options at introduction. Other keyboard
technologies will be investigated in parallel but may not be
available at introduction. If a better alternative does turn up,
it could be made available within a few months of introduction,
either as a standard keyboard or as an option. Although the
keyboard layout is nearly final, it has not frozen since it is
not yet on the critical path. One remaining potential variation
is the possible removal of the cursor cluster from the layout.
2. Engineering is concerned that the current cost objectives may
not be feasible.
3. Although there is no requirement to have the Problem Analysis
Guide (PAG) stowed within LISA, Engineering will continue to
pursue methods by which the PAG may be attached to the main unit.
4. The current display has a refresh rate of 59.2 Hz, which
violates the requirement of being within 1% of 60 Hz.
Engineering will arrange for a side-by-side demonstration of the
59.2 Hz display against an identical 60 Hz display to see if the
59.2 version meets the product's requirement.
III. SOFTWARE ENGINEERING AMENDMENTS
I.' It is too early to tell Whether or not it will be possible to
provide the level of integration and software sophistication
desired on a 128K LISA. Future MRDs and performance analyses
will resolve this issue.
2. Visicalc capabilities will be either built-into the File
Cabinet to create the ''VISICABINET'' concept, or created as a
separate product. This concern will be resolved in the
VISICABINET MRD.
3. Implementation details of the user interface may have a
significant impact on performance and product schedules
