The tactics that IBM might follow: o Expose the bare metal (below the microcode). Caution customers not to discard their source code this time around. o Provide compiler(s) as necessary, generating code for that bare metal. o Provide a UNIX-like (or not) bottom layer OS. For business and legal reasons, BSD-like might be preferred to GPL. o Provide z/Series emulation in software (Millicode? Possible hardware assists?), possibly based on one of the existing emulators. o Run z/OS in a virtual environment to support technology transition. Of course, there would be much wailing and gnashing of teeth from customers discovering that code compiled to the bare metal far outperformed their beloved Assembler programs on the emulated hardware. The vendor would need to cover its collective ears and encourage the customers to migrate to better technology. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
