The HFT and LFT terms were carried forth into POWER AIX. AIX 3.x had a home grown HFT with virtual terminals and some other semi-graphical features. AIX 4.X ported a STREAMs based console I/O stack from OSF and they called it the LFT because it lost all those features; users were directed to X11 for advanced terminal handling.

One of my employees spent a lot of time of in O= wego fixing the memory system (the whole thing was set up with these Xilinx= PGAs that were easy to update in the field). Amusingly, the machine-sp= ecific parts of the W4 version of the AIX kernel had more in common with th= e 370 version than the i386 version. I spent weeks out at the IBM Palo = Alto Science Center doing work on this project.
