Wave form photographs and notes on CSIRAC dismantling prepared by Jurij Semkiw with a polaroid camera on a Tektronix oscilloscope just prior to CSIRAC dismantling in 1964.
(These records were prepared as protection for any possible future development and historical record.)

Black 4-ring foolscap binder containing wave form photographs and descriptions of:
H. Register
Sequence Unit MkII - 2 pages
Memory
Time Selector
A Register
A,B Registers Multiplication, Input Trunk - 2 pages
B Register Multiplier Sequence Unit - 2 pages
C Register
D Register
Memory - 2 pages
(CSIRAC used specially designed test equipment in which time was depicted from right to left instead of the usual left to right because the least significant digit in the CSIRAC word was on the right. Thus the wave forms copied from the test equipment oscilloscope showed time increasing from right to left).
(These photographs would have been taken at Radiophysics, Sydney prior to CSIRAC moving to Melbourne).
