That would explain our joy if so--we went from a 0.5MIPS Formation 4000 PCM to a 9370 (1 MIPS?) to a 4381-1 IIRC.
BTW, http://www.roylongbottom.org.uk/mips.htm shows MIPS including 9xE, though I expect Shmuel already saw that. -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Pommier, Rex Sent: Thursday, July 31, 2025 10:10 AM To: [email protected] Subject: Re: 4381 capacity and performance >From ancient memory, the model 13 was rated at 3.3 MIPS and the 24 was 8 MIPS. > They were the first 2 machines I worked on.
