And they ran on processors with somewhat different architectures. The s/360 model 67 supported 32-bit addressing, while s/370 was limited to 24-bit addressing until XA in 1982 or 1983 began to support 31-bit addressing, not 32-bit like the model 67. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
