AS/400 name change?
"Looks like there may be a lot more than a name change. News/400 magazine has an article on page 19 of the September 2000 issue titled "Have You Bought Your Last AS/400?". In it Roger Pence describes a new IBM super server as a one-stop computing platform with "personalities" for NT/2000, Linux, AIX and OS/400." I read a few years ago (when OS/2 instead of NT had a fond place in IBM's heart) that IBM was intent on making OS/400 just one personality among the other IBM OSes on an IBM superserver. Didn't make any sense to me then but it was around the time when IBM would have been making some tough decisions concerning their IPCS (I don't remember all the names before and after for the Intel card). A superserver decision would have migrated OS/2 to run alongside OS/400 and AIX (and maybe a mainframe OS). They ended up deciding to drop OS/2 and continue with NT only on the external card. The superserver that Roger Pence describes is the currently stated direction for the AS/400. IBM has been trying to figure out how to run Unix programs on the /400, going back to implementing the POSIX Open Unix interface into OS/400 to now having the PASE AIX executable environment. With 4.5 now having the real Unix shell environments and IBM advertising that thousands of Unix programs have been ported to the AS/400, they're getting closer every day. However, the details I read of the PASE announcement didn't look as cheery about what it took to port a Unix program, but then I'm just an RPG wienie. NT runs on the IPCS, and IBM just stated that Linux will run on the AS/400 as it does on the mainframe and AIX. I didn't see whether Linux programs will have to compiled on an AIX box as PASE programs must be, and of course any Unix person would not consider PASE as Unix or Linux if that is the case. The alternative is that IBM was able to get their own AIX development environment running in the AS/400 PASE environment, in which case significant superserver news of AIX and Linux running alongside OS/400 would be realized. The addressing issues I saw precluded all but carefully rewritten Unix programs to be prepared under AIX before the executable could be copied over to the AS/400 and run. Hardly what one would call a superserver. As for NT/2000, I vaguely recall versions other than Intel being written, the DEC Alpha coming to mind. Compaq bought DEC and dropped that port. Did Microsoft finish their version for the PowerPC? I thought they dropped all other CPU efforts but the Intel version. If so, NT/2000 still runs on an Intel plugin card, again hardly qualifying the IBM box as a superserver. I will say this, this rumor has legs. OS/2 and Netware have fallen by the wayside and Linux has been picked up, but the game remains the same. A couple of things that come to mind was the Franklin clone of Apple with CP/M with both the 6502 and 8080 CPU's, and multi partition hard drives with a different OS on each partition, pick an OS, any OS, to boot up under. Neither did particularly well outside of hobbyist circles, and I have difficulty envisioning anybody but a serious hobbyist enjoying the prospect of running multiple OS's within different partitions on a couple of different CPU families in an IBM box. If this is to share disk space, the storage division of IBM has far too much clout. Ralph
