There are a few around - not the original, however. The hardware implementations available (XKL) are mostly used to run legacy apps. There are also (at least) 2 emulators around. These are mostly used by hobbyists, and outperform the original (last) PDP-10 on standard Intel hardware (500 MHz Pentiums). More on this on alt.sys.pdp10. In the early 80s there were Ada projects underway for the PDP-10. I even made my own attempt - lexer, parser and bits and pieces of code generation. Generics and elaboration issues made me realise I was in way over my head. The termination of the "jupiter" project (a bigger, faster PDP-10) at Digital terminated any serious Ada projects. I guess some of those efforts ended up in Vax Ada, but then I wouldn't know. Regards, Peter Hend�n
