Can anyone tell me, or point me to a site where I can find out for myself, if OS/390 1.3 will run on a z9 BC as well as it does on a Multiprise 2003/103. I don't need to restart the thread on the virtues of keeping current and using supported hardware and software. I have a very conservative/non-adventurous/reluctant customer. They never applied PTFs to 1.3 when it was supported. Our exhortations fail to overcome (possibly short-sighted) budget and training concerns. I don't even expect them to replace their 2003 which just went out of support in December but they have asked for a review of their options. <SNIP> If you mean natively, then given that OS/390 2.9 goes into a PI loop on a z/8x0 (not z/800) which could be put into 31bit mode (ARCHLEVEL=1?), I seriously doubt that it will be able to load the IPL text IF the z9(BC) does not natively support 390 Architecture (can be set to ARCHLEVEL=1 as opposed to only z/Architecture -- ARCHLEVEL=2). But to get the best answer, get the SAPR manual for that machine (the z/Series Biz partner you are using will have one). It will tell you the minimum supported SCP (operating system). You may find that z/VM is cheapest way to get there than upgrading the O/S immediately.
