It's not exactly fast though :-P

> … the virtual CPU thinks it is running at 1.05MHz. My testing shows that the actual emulated speed of the MIPS guest is around 70Hz at 740KHz. I run the 4004 at 790KHz, so the emulated guest is thus operating at about 74.73Hz. So time for the guest is dilated by 14,030x. This means that **a virtual second is, in real life, around 3h54**. Four hours per virtual second, basically!
