What does the A/ROSE (I may be misremembering the exact filename, but that's the gist of it) System Extension on one of the System 7 installation disks do? I've loaded it, to no visible effect. -- ---- Seth Tisue USMail: c/o Plaster Cramp Press ---- (tisu@midway.uchicago.edu) P.O. Box 5975 "Please to be restful.

It's an operating system from Apple for embedded systems running on 68000 cards. It's used on some Apple and 3rd party NuBus cards - I'm pretty sure the ISDN card uses it for example. -- michael -- Michael Peirce -- outpost!peirce@claris.com -- Peirce Software -- Suite 301, 719 Hibiscus Place -- Macintosh Programming -- San Jose, California 95117 -- & Consulting -- (408) 244-6554, AppleLink: PEIRCE

A/ROSE (Apple Realtime Operating System Extension) is used with intelligent cards, such as the TokenTalk and newer EtherTalk cards. It is an extension to the base Mac OS that makes it easier to build intelligent NuBus cards which include their own 68000 processors. =============================================================================== | Glenn L.

I expected we'd get some questions about the A/ROSE file in the Extensions Folder. May I expand? A/ROSE is the Apple Real-time Operating System Environment, a developer package (from APDA) for implementing real-time applications on intelligent NuBus cards. One part of A/ROSE is its kernel, a message-based pre-emptive multitasking, real-time operating system that runs on intelligent Macintosh II-family NuBus cards, the prime example being the generic Macintosh Coprocessor Platform card. There also is a Macintosh OS extension that provides interprocess communication for code on the main logic board. The A/ROSE file in the Extensions folder holds these pieces as well as related resources. For the first time with System 7.0, A/ROSE comes as part of a system release; it is installed as needed. As an extension, A/ROSE is useless unless there is client software to utilize it. The A/ROSE kernel and IPC were designed to be small, configurable, distributed across processors, and to achieve high throughput. The context switch on the 10 MHz 68000-based MCP card is 110 microseconds. IPC rates are more than 4000 msgs/sec on an MCP card and more than 10000 msgs/sec on a Macintosh II. (Sorry, A/ROSE does not provide pre-emptive multitasking for the Macintosh OS.) A/ROSE is currently used in several Apple products, including MacAPPC (IBM SNA Advanced Program to Program Communication), MacDFT (3270/3570 Terminal Emulation), TokenTalk, SMB File Transfer and MacX25, with more on the way; it is also being used by third party developers, mostly for in-house applications.
