The 1620 was my first computer. For some reason, UTA was still running one in 1975, and in my senior year of high school we used it for a new computer course. The course was mostly programming FORTRAN II, but I managed to find an SPS manual, and learned that on my own. I was hooked on

Hi All, This was (in 1976/77) a procedure where various front panel toggle switched were toggled, and a button was pushed. This caused the machine panel lights to flash in a pattern. It was called "rippling core" and was to invalidate any data left prior to IPL'ing the machine with a

Prior to to z/OS 1.3 (i.e., some 15 years ago) there were reasons for increasing the value of the ERV parameter and from time to time one can still see values of up to 50,000. Since the ERV is being restarted there are no good reasons for such exaggerated values and I'd consider the default of

Bob, Rather than alter the ISPF panel logic, an alternative would be to create a USERMOD to replace the contents of the ISFM701 message with : ISFM701 ' ' .ALARM=NO ' ' This will cause the ISFM701 message to only overlay a single blank on the underlying SDSF main panel. Note that if you

Re: SDSF initial display and z/OS 2.3

The addition of the IBM logo on the SDSF main panel goes back many years - sometime in the late 1990s to early 2000s I believe. It was probably influenced by a lot of Windows software having similar "splash" screens and was trendy for a while. Until recently, the number of SDSF primary
