Message-ID: <1553@uw-beaver> Date: Wed, 29-Aug-84 01:42:55 EDT Article-I.D.: uw-beave.1553 Posted: Wed Aug 29 01:42:55 1984 Date-Received: Sat, 25-Aug-84 05:55:04 EDT Sender: daemon@uw-beave Organization: U of Washington Computer Science Lines: 29 From: Robert (LISPer 68K)Heller I have several questions about the Mac: 1) Does anyone KNOW when Apple will be offically selling/shipping 512K Macs? 2a) I am working on an implementation of Common LISP for the 68000 processor (using a Sage II) and would like to port this system to the Mac at sometime. This means transfering the assembly language source code from my developement system to the Mac and re-assembling the beast. (I suppose I may have to translate the assembly source if the assembler is different enough.) Then I will need to write a medium-level I/O interface (File-System calls) in assembly language. And finally link it all together. What I need to know: are the disk drives used on the Mac (3.5" FlexyDisks) available "bare" - that is without the controller for the Mac? What I may do is connect up such a drive to my developement system and create Mac-readable disks. Also: is the disk format and file structure of these disks documentated anywhere? 2b) I may want to implement a stand-alone version of Common LISP for the 68000 - in which case I will need to know how the boot (P)ROMs in the Mac boot up the Mac, that is, is there documentation on how to write a bootstrap loader for the Mac? Thanks in advance for any help. Robert Heller (Media Research, Ltd.) Heller%UMass-CS@CSNet-Relay
