A 4300 system was recently decommissioned out West, and the system was broken apart. I think the processor and DASD went to a collector. The card handling equipment will be coming east to me - real S/360 era stuff that still works.
It seems the 4300 line were perhaps IBM's best machines - they never broke, apparently. Mine (4331) never had a service call in its 30 year working career. Other collector have similar stories. But no, I do not know of any IBM older than a Z still in working service. I certainly would like to know, now that those boxes should probably now be saved. The same applies to older tape, DASDs, and communication boxes. And software, of course... Yes, I know this is an IBM list, but the crown for elderly machines still in service belongs to Control Data. There are still a few Cyber 180s in active duty, and even a 1700 going *past* its 50th year. -- Will On Thu, Nov 19, 2015 at 5:59 PM, Phil Smith <p...@voltage.com> wrote: > Is anyone running on real hardware that's older than a z9?
