Indeed, the Manchester Baby machine of 1948 had 32 words of memory, and
a 3 bit opcode field, despite this it was fully functional a stored
program computer, if somewhat limited in its application.
On the Zuse machine, there is a paper by Rojas which discusses how to
make it into a general purpose computer :
Rojas, Raul: How to make Zuse?s Z3 a Universal Computer.
IEEE Annals of Computing, Vol. 20, No. 3, July/Sept. 1998..
This web page also seems apropro :
