IBM pulled a very dull little clutch of announcements from its grab bag yesterday, saying that AIX/370 and AIX/370 NFS would be generally available in the first quarter of next year, and killing off the previous IX/370 Unix, support for which ends at the end of 1990. It teamed with Adobe Systems Inc to announce a new 031 version of the six page-per-minute Personal Page Printer II PostScript printer, which kills off the original version and adds the facility to switch under software control between different printing languages over serial, par allel and AppleTalk communications interfaces without manual intervent ion. It now supports PostScript, HP LaserJet, IBM Proprinter and Diablo 630 languages and has 47 built-in fonts. It’s $5,000, next week. IBM has finally taken to heart the moans at the price of OS/2 Extended Editi on. Upgrading from Standard Edition is cut 27% to $490 for the first copy, 33% to $320 for subsequent ones; and upgrading from the 3270 Emulation is reduced by 7% to $680.
