Um. More like a natural progression.
Like 8086->80186->80286->80386->80486->...
No, the PDP-6 and PDP-10 have identical instruction sets, and in general, a
program that will run on one, will run on the other. See "decsystem10 System
Reference Manual" (DEC-10-XSRMA-A=D", pg. 2-72., which provides a 7-instruction
code fragment which allows a program to work out if it's running on a PDP-6, a
KA10, or a KI10.
The KA10 is a re-implementation (using mostly B-series Flip Chips) of the
PDP-6 (which was built out of System Modules - the predecessor to Flip Chips).

New subject: Happy birthday, PDP-8!
And how is that different than the Intel line of CPU's? Backward
compatibility, while adding features as it progressed.
The KA10, KI10, KL10, KS10 all added something to the mix that their
predecessors did not have.
To call something a "clone" infers a second party making as close of a
copy as possible to the original. The KA10 was not a "clone" of a PDP-6.
