Dear List: An IBM 4361 Model Group 5 had the ECPS feature -
Extended Control Program Support (ECPS) -- offers VSE mode, VM/370 mode, and MVS/370 mode. These modes provide microcode assists that make the system control programs operate more efficiently.

Yes the 3310 were FBA (as well as the 3370's). We had one as a toy and were not impressed with the speed.
