Yes, everything sounds like AS/400. And System/38 before that. Which was sometimes known as "baby FS," where FS was IBM's Future System project. In order to contains every object in a single address space, FS was to have an 80-bit address space. FS was canceled in 1975 (per Wikipedia). System/38 had a 48 address space (or rather, object space), and AS/400 increased it to 64, or maybe 65. System/38 had two layers of microcode: Horizontal (like other IBM machines) and Vertical (which was the VM interpreter for the instruction set exposed to end users). But few customers used the VM directly. They just programmed in RPG or COBOL, or bought program suites written in RPG or COBOL.
