General information
Machine type: 9576
Announce date: October, 1992

Excerpt from the original announcement letter;

"The new Premier PS/2(R) 76, 77 and Ultimedia(TM) M77 are full 32 bit 486 Micro Channel(R) systems designed to enhance the PS/2 product line at very attractive prices. These systems are offered in two mechanical packages, the PS/2 76 provides 3 slots (2 slots available for expansion) and 3 bays (1 available for expansion) and the PS/2 77 and M77 provide 5 slots (of which 4 slots on the 77 and 3 slots on M77 are available for expansion) and 4 bays (of which 2 bays on the 77 and 1 on the M77 are available for expansion). Standard features on these new systems include a SCSI Controller with larger and faster hard disk drives, video is provided via the XGA-2(TM) Display Adapter/A designed to meet the International Standard Organization (ISO) requirements, support for up to 32MB of 70 ns memory on the planar, two 9-pin serial ports, A high speed DMA parallel port and OS/2 2.00.1 installed on the hard disk drive and ready for use in a standard configuration. The enhanced IBM mouse is a standard feature in all the systems. In addition, M77 Ultimedia Models come with a CD-ROM, built-in audio functions and a variety of Ultimedia sampler applications. The systems support up to 32 MB of 70-ns memory on the planar in four SIMM sockets. All systems ship with one 8MB single in-line memory module (SIMM) located in SIMM socket 1 leaving three SIMM socket available for memory expansion."
