“We know there’s been a lot of erosion”! No we don’t. Prove it. Because 50 listers have said so in the last decade or two? Plus, there are thousands of new MF customers throughout the world. Easily proven. IBM has been around for over 100 years. (1911) Not many companies can say that. I’d bet they’ll be around for many more decades.

I expect that's a marketing number, and I strongly suspect it's high, and includes internal machines and Kyndryl. At the peak of System/370 in the 80s the claimed number I heard was about 20,000, including MVS, VM, VSE, and TPF. We know there's been a lot of erosion, plus simple consolidation both because of mergers and more LPARs and CPUs per CEC. So 10K CECs just seems.very very high to me. I'd bet on more like 2,500 if I had to put money on it. But of course we'll never know because IBM has no reason to tell us. Can't blame 'em for that. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
