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. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. II. USER INTERFACE SOFTWARE THEFT PROTECTION USER SET-UP AND CUSTOMIZING TERMINAL EMULATION VISICABINET WORD PROCESSOR GRAPHICS EDITOR PERSONAL APPLICATIONS MASS STORAGE PERIPHERALS PRINTERS NETWORKING AND ELECTRONIC MAIL DIAGNOSTICS/TESTING BUSINESS GRAPHICS INTRODUCTORY INTERACTIVE MANUAL 'OEM PRODUCTS (DEVELOPMENT TOOLS) May 31, 1980 May 31, 1980 June 30, 1980 June 30, 1980 June 30, 1980 June 30, 1980 June 30, 1980 June 30, 1980 June 30, 1980 June 30, 1980 July 31, 1980 July 31, 1980 July 31, 1980 August 31, 1980 August 31, 1980 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 •. These details will be resolved by May 1, 1980. 4. The degree of integration of the various software· modules has not been determined. Final resolution will involve basic capability/performance tradeoffs. IV. INTRODUCTION TARGET DATES The LISA system will be available for first shipments (i.e., introduction) by March 23, 1981, the date of the National Computer Conference Office Automation Show in Atlant…
