It is, although TIMI does not exist in the hardware – it is a virtual architecture that has been implemented multiple times in different hardware (i.e., CPU's – IMPI, IBM RS64, POWER, and only heavens know which CPU IBM uses today).

The software written for this virtual architecture, on the other hand, has not changed and continues to run on modern IBM iSeries systems, even when it originates from 1989 – this is accomplished through static binary translation, or AOT in modern parlance, which recompiles the virtual ISA into the target ISA at startup.
