They exist,  I have seen several TTL motherboards with TTL for 386 
and 486.  Some hybrid TTL and one or two chipsets as well.

CHECK that PIII!  Many PIIIs high clock CPUs still use 100MHz FSB, 
there is PIII 600 512K but 2.05V, not too many late 
revision slot 1 supports this.  My friend is using two of PIII 800 on 
late revision P2B-B and P2B-D, yes true slot 1 PIII 800s.

Agreed.  I keep some old 386/486/pentium boards around.  In fact, I 
have small collection of PS/2 machines.  Not the playstations! :)
