Medley Interlisp
2023 Project 18 March 2023
Interlisp.org
2

 What have we been doing?
+ Adapting the system to current environments and standards
	hardware: keyboard, mouse, display, CPU (64bit, little endian)
	software: standard C, Unicode, Posix, UI Guidelines
+ Lower barriers to entry

+ Demonstrate unique and original features
+ Help with revival of other applications built using system
+ Improve maintainability for future users
+ Gather and update documentation

Who might use Medley Interlisp?
- Retrocomputing enthusiasts
- Researchers, IDE tool creators, looking into ideas
- Software and AI historians (present and future) 
- Software archivists (SPN, technical infrastructure)
- Developers of new applications
2

Who is involved?
+ Some of original developers from Xerox PARC (in 70's )
+ Developers of s using Interlisp (recursive revivers)
- Open Source contributors   
-  Students of computer science and history
+ Friends, enthusiasts, and ... you?

More on Modernizing Medley
Goals
- Adapt Medley UI to current hardware
- Make Medley work more like current applications for comfort
Mouse: Wheel Scroll, Window move on title, Window resize on corner. Warning: Exec windows. Consolation: you can do it all with menus. Reduction: some menus are invoked by "middle" mouse button which on some mice is hard to press.
Keyboard: Desired state: compatible keystrokes. Subtasks: decide what keystrokes do what; slash through umpteen layers of keyboard re-iterpretation.
Display: Color, high-resolution displays, modern fonts.

More notes on Running on Modern Systems
- about K&R C and C standards; type declarations, big-endian vs. little endian, 32 bit vs 64 eliminating errors, file-sytem changes, process handles, bugs left over from 24- to 28-bit address space
- docker, installers, CO/CI(?), two levels of virtualization
- online.interlisp.org: connect in seconds. 
- Mysteries in the code we inherited, "software archeology"
- Robust "loadup process", all day vs seconds
- bytecode virtual machine aids portability.
