Did you ever see a 1052-7, or even a 3210, on an MVS system? Admiitedly the D U message flood is a nuisance even on a 3270, but every shop that I saw used 3066 and 3270 for consoles, with hardcopy on syslog and no keyboard-printer consoles. Was anybody here on a S/370 that used a 3210 or 3215 as an MCS console?

I am wondering if some of the problem is the inappropriate default. I remember putting a zap on a console display module so that the default was 1 not 100 when a display unit command was issued.. The result of displaying 100 device statuses on a 1052 (deserving of the sledgehammer award) bouncing ball console printer was painful. This lasted from MVT well into MVS and was the subject of a requirement. If it takes 300 concurrent threads to run the default of 100 qualifies for being inappropriate. Also someone whose talent is improving systems performance may be needed. I was the type of person who would not have designed a good system but I could in many cases drastically improve the performance of an existing systems, preferably in COBOL although I did a speed up a couple of assembler programs.
