Hello list,
out of curiosity: Does anybody know where the two pictures of the Siemens 4004 CPU
uploaded on
http://bitsavers.org/pdf/siemens/4004/Model_15/pictures/
where taken? Are these from the unit being part of the SAP collection at CHM?
Cheers,
Pierre

For those who doesn't know it:
The Siemens 4004 was basically a rebadged RCA Spectra 70, so this is a
RCA 70/15. Maybe technical/service manuals for this system come up.
(the owner already searched everything incl. bitsavers, of course)

Thanks for the elucidation. I forgot that Siemens also had a 4004 model
CPU and was wondering here how that mess of wires had anything to do with
the Intel 4004 :)

No, thanksfully this machine is still in Germany. It is nor far from me
BTW ;-) I know where it came from and who has it now. It is complete
with peripherals (storage, card reader, console, printer) and
hopefully, will be running soon again :-)

I once ran into a Siemens computer used to control a Contraves precision drawing machine.
I found recently that those were mainly used for drawing master plots for printed maps. I
remember nothing about it except that it used hex digits 0-9, where 9 could also be
written as A, and then B to G for the digits representing 10 to 15. Does that ring any
bells?
