terminal illness and the site became inaccessible. In January 2021 Olivier Gossuin launched a new Organisr II User Forum. Another legacy that Cornet left Organiser II users is Psi2Win, the Windows PC comms link server. This Windows-friendly server was developed using Scherphuis' reverse-engineered comms link protocol. In the winter of 2013, Scherphuis created his web site with the aim "to be an archive of Psion Organiser II information and software that might otherwise be abandoned and lost". Hardware developments have continued with Olivier Gossuin, a Belgian enthusiast who has created a microUSB CommsLink, 256 KB RAMPak, 512 KB FlashPak, and microUSB Power Supply. These, with other Organiser II hardware and software, are still available from the West Yorkshire Psion Store. Massimo Cellin created the Psion Facebook group in the autumn of 2015, servicing all the Psion products including the Organiser II. Members of the Facebook group include the former editor of IPSO FACTO, the 1980s and 1990s newsletters of the International Psion Pocket Computers User Group, copies of which are still available from Scherphuis' archive.

Some of these models have radically different keyboard layouts. Subsequent hand-held devices The name "Organiser" was not used for later Psion handhelds, such as the SIxteen-Bit Organiser (SIBO) family Psion MC400 laptop, the Psion Series 3 and the 32-bit Psion Series 5 machines, which were of a clamshell design with a QWERTY keyboard. As to hardware architecture and operating system, these had no links to the earlier Organiser range, other than the end-user programming language, which shared a great deal of structure with OPL. The SIBO family, and the improved version of the OPL language (with window and focus controls), was replaced in 1997 by a new ARM architecture-based operating system EPOC32 written in C++; the latter was later sold as the Symbian operating system, which until 2010 was the most widely used OS in smartphones, being in 2011 displaced by Google's Android OS. This change was more significant than appeared at the time. The consumer-grade high-level programming language still shares features with OPL, but the developer toolkits were from then on focused on programmers familiar with C and only the Symbian operating
