The original IBM 360 assembler that we used in Kingston, NY in
1966 was actually a cross assembler which ran on IBSYS on a
7094 across the road.  We used a three tape rotation system.
This is probably why the 360 had an ASCII bit in the PSW.
Some of the code we were working on in those days can still
be found in the SE's room.  CEDA = CPU Error Detection and
Analysis and SEREP = System Environment Recording, Edit,
and Print (prints out the machine check area after a
machine check; what's where is very model dependent).
