Eeek - that site doesn't have entries that account for a number of year of my IT experience:

Ramis II - a semi-hierarchical DB
Mantis - a CICS/COBOL alternative for IBM mainframes
NatStar - a semi-OO language that generates C++
Forte - Java without the curly braces but built for distributed deployment

If there's something out there that fills a small niche and is no good to anyone after a few months I seem to get stuck with it!
