I am preparing to develop some software which will have to be able to run on the whole APPLE II family: IIc, II+, IIe, IIgs (no I's, III's or MACS) The questions I have are: Is a LAZER128EX (apple clone) a suitable machine to develop sofware that must run on all these. Note that I don't expect to customize the program to any of the machines, it should run the same on all of them. Where can I find, in succinct form (book, article, etc), the pertinent differences among these machines that will guide be in the above task. Jeff Sicherman jajz801@calstate.bitnet

The LAZER128EX is a suitable machine from the compatability point of view, but if you plan to write machine code - don't use the uncommon addresses of the machine. I mean write ALL your routines, and don't make extensive use of monitor based ROM routines. You'll probably have to stick to DOS 3.3, cause //'s & //+'s can't boot Prodos. You can't use open-apple & closed-apple keys, too. As for books - well, I recommend Apple's old reference manuals, which you have to dig for first, then enjoy for their good machine description. I have my old //+ manual, and that sure helped when I got my //e. --- Eran Lachs, Ben Gurion University, Beer Sheva, Israel Bit : clap100@bgunos

You can't use open-apple & closed-apple keys, too. i dont know about the possible copyright infringements but i'd simply copy the needed ROM rtns into my code.... for the ][+ : mine does boot ProDOS nicely; the open/closed-apple buttons are on the joystick... have phun -- Heiko Blume # DOMAIN: blume@netmbx.UUCP { BITNET: ( mixed } Seekorso 29 # BANG : ..!{backbone}!netmbx!blume D-1000 Berlin 22, West-Germany # Phone : (+49 30) 365 55 71 or ... 365 75 01 Telex : 183008 intro d # Fax : (+49 30) 882 50 65
