And all the OS/360 variants were so late that they introduced three

systems that were usable by customers. First came Basic Operating
System/360 (BOS/360), which was pretty much cards in and out (plus
printer),
The 1620's I resurrected at USL in Lafayette, La. were card in and out.
There was also a printer. It had an assembler deck and a Fortran compiler.
I suspect that the 360 would have slipped in there except for the fun
getting arithmetic to match on the machines.
Had 2 cpus, one card reader / punch and a printer for the 1620.
thanks
