SN7400 RS to "Old style" T - trigger

minimal counter configuration experiment ::

?! it's even possible . . . in theory . . .

+MMXV-02-08 the pulse T-trigger speed test
- thought to run this test in real but . . . what's the point -- it'd take also to build/test/verify a 15M detection circuit - that'd be more complex than the one below . . .


notice the complexity differences in between above and below circuits -- the speed difference seems to be roughly 1:3 . . . such as does it weigh up to gain some more speed by this "investment" , becides pushing the chip to it's limits increases the likelihood for errors
! Update 2021.08.01 :

found an error in the above circuit , a repair as a   (at the input the XOR must be faster than the NAND-s or the NAND-s should be delayed to be slower for proper operation)
