Orphaned technology is a descriptive term for computer products, programs, and platforms that have been abandoned by their original developers. Orphaned technology refers to software, such as abandonware and antique software, but also to computer hardware and practices. In computer software standards and documentation, deprecation is the gradual phasing-out of a software or programming language feature.
For users of superior technologies that have been withdrawn from the market, there is a choice between maintaining their surrounding environments in some form of emulation or switching to other supported products and losing those capabilities.
Some well-known examples of orphaned technology include these pieces of technology:
- Coleco ADAM - 8-bit home computer
- TI 99/4A - 16-bit home computer
- Mattel Aquarius
- Amiga - 16/32-bit computer
- The Apple II series - 8-bit computer
- Apple Lisa - 16/32-bit graphical computer
- Newton PDA (Apple Newton) - tablet computer
- CP/M - 8-bit program loader
- Commodore 64 - 8-bit computer
- DEC Alpha - 64-bit microprocessor
- HyperCard - hypermedia
- ICAD (KBE) - knowledge-based engineering
- Javelin Software - modeling and data analysis
- LISP machines - LISP oriented computers
- Classic Mac OS - m68k and PowerPC operating system
- Microsoft Bob - graphical helper
- NeXT Computer
- OpenDoc - compound documents (Mac OS, OS/2)
- OS/2 - next generation
- Prograph - visual programming system
User groups often exist for specific orphaned technologies, such as The Hong Kong Newton User Group, Symbolics Lisp [Machines] Users' Group (now known as the Association of Lisp Users), and Newton Reference.
