We hope that this will enable more hands-on experience with Smalltalk in the universities, and that it will give other interested parties a chance to experiment with the system. Release 0.2 supplants an earlier release (March 1985) that ran only on the Macintosh XL. Two images are supplied with the new release: level 0 and level 1. Both images incorporate the following improvements: • Improved volume management capable of supporting file server access • Automatic spelling correction for variable and message names • Ability to handle multiple images on the same disk • A single interpreter works on all machines and expands to use extra memory Level 1 requires 1 MB or more of memory, and incorporates further improvements: • Total object capacity has been raised from 24K to 32K • Can expand to take advantage of 2MB memory on the XL (available from AST Research, Inc.) • Able to run on some Macintosh cC?mputers with 1MB or more of memory (available from various manufacturers, but must be contiguous and must follow ToolBox memory organization) Level 0 is a stripped-down image which will run on the Macintosh 512K. It is missing many of the classes in level 1, but it retains full support for browsing, editing, compiling …

Smalltalk-SO™ for the Macintosh™ 0.4 Release Note June 9, 1987 Overview: The main purpose for the 0.4 release is to provide a Smalltalk that runs well on the Macintosh SE and Macintosh II (as well as the Macintosh Plus and other Macintosh models with at least one Megabyte of RAM). Since Smalltalk is implemented using some non-standard techniques, a few changes had to be made to Smalltalk 0.3 to make it work on the new machines. While we were making these changes we fixed a few other bugs and added several features. The Smalltalk 0.3 documentation still applies except as noted in this release note. Warning: Images and the interpreter from this release are not compatible with those from version 0.3 or earlier versions. Any work you want to move between 0.3 or earlier Smalltalk versions and this 0.4 Smalltalk release must be moved via file-ins. Note: You must run with version 4.1 or greater of the System file. System 4.1 is provided with the release. This does not apply to the Macintosh XL; however, on the Macintosh XL you should be able to run with System 3.2 (which you were probably using already). Installing the release: In general, follow the directions in the Smalltalk 0.3 manual except as noted below. If you do not have an up-to-date system (System file 4.1 or greater) on your hard disk, boot from Smalltalk Disk 1 and move the System file and Finder from Smalltalk Disk 1 into your System Folder. If you wish to preserve the fonts and desk accessories in your old System file you should use the Installer to install System 4.1. ( If you already have the 0.3 Smalltalk-80.sources you don't need new ones (they have not changed for 0.4). If you don't already have the sources, use DivJoin to join the Smalltalk sources on Smalltalk Disk 3 and Smalltalk Disk 4. The Smalltalk sources must be placed either in your root directory or in the directory where you will run Smalltalk. If you plan on running Smalltalk from more than one directory, place the sources in the root. To install this release on a Macintosh XL, you will have to move the files to single-sided disks before the Macintosh XL can read them. To do this, you will have to join the larger files using a Macintosh with SOOK drives then divide them again onto single sided disks. Differences for Installation on a hard disk: (refer to pages 3-4 of the 0.3 manual) 1. Smalltalk-80.sources is now a two part file on Disks 3 & 4. It used to be a four part file. You will still have to join the file. 2. You no longer have to join Smalltalk.image. It is now a complete file on Disk 2. Differences for Installation without a hard disk: (refer to pages 4-6 of the 0.3 manual) 1. Most of the process described in the 0.3 release notes tells you how to create two double sided disks named System and Work. The configuration in which Smalltalk 0.4 is shipped on double sided disks makes Disk 1 already set up as the System disk and Disk 2 already set up as the Work disk. All you need to do to run the 0.4 release witho…

This is the starting point for you to work with disks and launch applications. Servant replaces the old starting point (created by the Finder program in the System Folder) with a more powerful desktop that is an accessible part of your work environment at all times. As the central application between you and your disks, Servant will: • Perform desktop tasks faster, more conveniently, and more informatively. • Allow you to keep open numerous applications and disk windows at the same time, and to switch from one to another instantly by clicking in an application or disk window. • Give you the ability to modify an application by directly accessing and editing its resources . • • • On the Impetus for Servant Servant is a replacement for Apple's Finder program. A lot of programs like spreadsheets, word processors, and database programs are constantly improving. Every month there's a new one coming out that ups the ante a little bit and forces all 1 the people who have the other ones to improve their product to make it better and better and better. That's just the best si…

Thu, Mar YaccEqu.Text on Mac onlisa on Yacc .EQU .EQU .EQU 16, 1989 11 :31 PM 0 0 '·----------------------------------------------------------------; System Constants ;----------------------------------------------------------------Physical Device Equates The YACC is a meg machine with memory management that aliorJs mapping of the memory into 1 kilobyte pages. There are 8 video p1anes which are 640*480 pi;.~eis in size. This is 37.5K of ram per plane; the 1K resolution of the pages force an allocation of 38K for each plane. The Video DMA system uses physical addresses 19 to 17 for the selection of the 8 planes, thus forcing the division of the physical 1 meg of memory into 8 128K partitions. There is a 16 bit register that is 1oaded with a physical address that points to the start of the frame buff er in each of the 8 p1anes. The Sound subsystem makes al 1 accesses from partition O, which has addresses 17, 18, and 19 = .(i. It ai so has a 16 bit register i·Jh ich points to the start of the sound buffer. The system rJi 11 fetch a 16 bit value at the start of video scan 1ine (15.734 KHz horizontal scan rate), of ~~hich the low 10 bits are used as input to a PWM c irwi t. The PvJM circuit di vi des the line into 585 cycies; a value of 585 or higher will turn on the sound for the entire i ine whi 1e a value of 0 rJi 11 turn off the sound for the 1ine. The Sound DMA system will continue to fetch successive words of data until a word is read that has bit 15 = 1, whereupon the circuit rJi 11 reset the starting -:.iddress to the int iai vai ue in the 16 bit register. The floppy disk PliJM circuit for speed control is two 8 bit registers/counters that are written in para1 lel. . When 16 bits are written, the lm:.s 8 bits are loaded into a PWM Low register and the high 8 bits are laoded into a PWM High register. The circuit provides Pulse Width Modulation and Pulse Frequency Modu1 at ion. Each register is fed into a counter that increments at an 8MHz rate until it reachs 255, ~·Jhereupon it hait and reload itself. The other registericounter is enabied and it folim&Js an identical process. The number of times that both counters increment is proportional to the square-wave frequency that is produced • ~Ji th a sum of counter increments equa 1 to 256, a square wave of frequency 31.25Khz is produced ( 1000/ \256* ( 1000000/BMHz))) • The vaiue in the PWM_Low register/counter divided by 256 is the proportion of the square ~-Jave that rJiii be 'low and the vaiue of Pl>JM_High divided by 256 is the proportion of time that will square wave will be high. The memory management hard~111are consists of 2K ;{ 16 of read/write registers. 8 megabytes can be mapped but only 1 megabyte can be mapped at any one time. Any 2 accesses that has the l ow 19 bits the same and the high 3 bits are different v4ill cause a memory translation error. To address 1 meg, bits 19-10 are provided by the MMU and 9-1 come directly from the address. The high 3 bits (22-20) are used b…
