Just to clarify my understanding of your position, is a system with a CPU
chip (say one of the 68K models) with only ROM not a 'stored program
machine'?

PS: You really should look at the book ("ENIAC In Action"), and not rely on
the articles; it's later, more coherent (not being split across a handful of
papers), and much more detailed (e.g. it includes the instruction set for
the
'programmed' version of the ENIAC).

Note that most of the BRL references in the three articles in the IEEE
Annals of the History of Computing are available online through DTIC.
Search using Google Scholar.

Unfortunately the referenced manuscripts located in private archives appear
to remain inaccessible to the general public.

Tables I thru III in the second paper, offering a set of side-by-side
comparisons for "ENIAC, EDVAC, and three other computers of the late 1940s"
are well worth contemplation.  The third paper puts a practical perspective
on the somewhat more theoretical perspectives of the first two papers. "1948
ENIAC" was a quite interesting reorganization/application of the computing
resources available in the "1945 ENIAC".

It looks like the somewhat less expensive paperback for "ENIAC in Action" is
due for publication in January.

Noel:  Does the book make any attempt to trace any technological/social
effects *from* the "1948 ENIAC" to other computer developments?  Or are we
to conclude that the "1948 ENIAC" was aa significant "existence proof" for
aspects of the First Report (and evidently quite productive as a
computational tool) but sterile with respect to direct progenitors and
impact on other computer developments of the late-1940's?  For example, do
they cite any evidence that either BINAC or early UNIVAC were other than
"from whole cloth" in nature?  Any of the "IACs"?  Perhaps more at the level
of "coding style/procedures" than hardware
architecture/design/implementation?

As an engineer, I like systems that "get stuff done" and the "1948 ENIAC"
certainly qualifies.

As a (computer) scientist I like what SSEM demonstrated and the fact that it
had direct (physical & intellectual) offspring.

As a practical person I like that the SSEM directly led to the "first
general-purpose commercially produced computer" (Ferranti Mark 1).

There's a lot to like in the span of 1945-1955!
