RAM caching must be disabled when running Smalltalk~ This can be done by using the Control Panel desk accessory. 2. The present release does not fully support the Hierarchical File System. As a result, Smalltalk can only read and write files at the top level of the file system. 3. With SOOK diskettes, it is possible to run the larger Level 1 system on a Macintosh Plus ~ven without a hard disk. However, it is not possible to use DivJoin to join the file Level1.lmage without a hard disk. If you wish to run Level 1 without a hard disk, you will have to find a friend with a hard disk and an SOOK drive, then use their system to join the file Level1.image and transfer it to your diskette. 4. The current Smalltalk interpreter expects the keycode of the enter key to be 52decimal (34hex)· This is correct for the U.S. 512K Macintosh keyboard, but it should be 49decimal (31hex) on the international 512K Macintosh and 76decimal (4Chex) on all Macintosh Plus keyboards. Smalltalk users who have one of these keyboards can correct the problem by making the following patch to the Smalltalk interpreter (not the image): in block 29decimal (1 Dhex>• offset 1B4hex• is the sequence OC2S 0034. Change the 34 (the expected keycode of the enter key in hex) to the keycode generated by your keyboard (e.g. change it to OC2S 0031, for the European Macintosh 512K keyboard). Note: to patch the interpreter you will need atool which will allow low-level editing of disk files; one such tool is Fedlt. Copies of Fedlt are dist,ributed on a "shareware" basis by many Macintosh users groups and bullitin boards. To become a registered Fedlt user and obtain the latest version, send $30 to: John Mitchell 939 E. El Camino Real, Suite 122 Sunnyvale, CA 94087 This release was completed long before the Macintosh Plus existed, so you may encounter other problems when running on the Macintosh Plus. The next release of Smalltalk will address these issues and add many other features as well. All purchasers of record will be informed when the new release is available (several months from now).
