"II in a Mac" is Apple II simulation software for Macintosh. It simulates an Apple II with a clock, joystick (but no mouse), and four 5.25 inch Disk II or two 3.5 inch disk drives. An 80 column card in slot #3, a serial card in slot #2 with adjustable baud rate, data length, parity, and stop bits, and a RAM card with up to 3.6 Mb RAM (Applied Engineering RAMWords standard) in slot 0, are also simulated. The software is distributed on copyable 400K Macintosh disks. It is published by Computer:applications, Inc., 12813 Lindley Drive, Raleigh, NC 27614. Telephone 919-846-1411. It is sold by the publisher and by distributers such as Mac Warehouse. "II in a Mac" is very slow. It operates at about half the normal speed of a //e or //c. For anyone who is accoustomed to an accelerated //e or //c, the speed is a significant factor. It is said by some that it will operate at normal 1 MHz //e speed in a Mac II. A very serious problem with "II in a Mac" is its inability to reliably produce open apple-X or closed apple-X commands, where X is some additional key (such as ? or P or ESC). One is supposed to produce open apple by pressing OPTION and O ; closed apple by pressing OPTION and C. For open apple-X, OPTION and O are to be pressed together, then released, the X is to be pressed. Occasionally this works. Generally, either nothing happens or something unpredictable. I tried this with version 2.5 and 2.53, on two different Mac Plus. Same problems in all cases. Since AppleWorks is very dependent upon open apple-X commands, "II in a Mac" is useless for AppleWorks. AppleWorks enhanced with Timeout utilities should not be used with "II in a Mac" . A crash attributed to attempting to execute an undefined 6502 instruction is reported. AppleWorks v2.1 will not work with "II in a Mac" v2.53. Summary: Not recommended. Might be useable in situations where no open or closed apple-X commands are used, and in which nothing that might be considered an illegal opcode is used. ****DISCLAMER: My comments, etc., are my own shakey opinions ******** | Bruce P.
