Mistake creates on translates uS in kHz.
in timeline.pdf - file (AD) this frequency is 108 kHz and this millions time replay for 39 years ;-)
Wrong! in 4004_datasheet.pdf - file this frequency is 92,6 kHz (directly not writed).
In file 4004 have 10,8 uS machine cycle and 1,35 uS minimum clock time. Clock divided by 8 equals 10,8 uS and mean 92,6 kHz.
39 year this "feature" didn't notice.
