Calamus under (!MM) won't start: Insuffient memory.

I have today downloaded the current demo version of Calamus from the net. Unfortunately the program won't let itself be launched, and reports that not enough memory is installed. That can't be right as I am using the program under (!MM) with 320 MB of RAM. Is there something that one has to pay regard to with (!MM) in this respect?

Calamus is relatively sensible about critical memory settings. However the problem can usually be solved very quickly:

• Check how much memory (!MM) is really getting from the Mac OS. The best way is to start (!MM) and then in the (!MM) menu click somewhere at the right beyond he actual menu entries to open the Applications popup. This shows on the last line how many kB of RAM has been allocated to (!MM). Possibly there is simply too little shown there.
• Then use [Apple]+[W] to switch to the Mac OS side and in the (!MM) menu (Mac mode!) look under Memory allocation to see what values have been entered here. There are 4 memory values with which the (!MM)'s memory sharing is defined, and an important switch Lower I/O region usable for programs. Please switch this on.
• After this set the following values to give (!MM) roughly half of the physically available RAM, for example:

  Minimum ST: 80000 KB = 80 MB Maximum ST: 160000 KB = 160 MB Maximum total: 160000 KB = 160 MB Minimum Mac OS: 8192 KB = 8 MB

• In addition switch on Allocate time to Mac applications, so that MacPrint can really output via the Mac OS Quickdraw to Mac printers.
• When (!MM) has been configured in this way, it has to be terminated and restarted. (If it doesn't want to start, then it may not stomach these memory values for some reason. In that case keep the [Alternate] key pressed during the next start of (!MM) so that the memory setting dialog appears again, and change the values slightly in that.)
• When (!MM) is started one more, check in the menu again that really around 70-150 MB of memory is available in MagiMac now. (Some will be swallowed by (!MM) itself plus jinnee etc. ...)
• Now start Calamus. If Calamus still objects, this is probably due to too much or too little memory being left free for (!MM) in the CALAMUS.SET file. In that case rename the CALAMUS.SET file (say to CALAMUS.SE_), so that it will not be loaded the next time that Calamus is started. Then load the required modules manually and call up the System Parameters module (SYSTEM.CXM). In that, at far right of the dialog, set the memory values for ST- and TT-RAM to 2 MB each (the Vector Output Buffer may be some 128 KB) and after closing the dialog resave the Calamus.SET file (Options menu, Save System Settings). Quit Calamus and then restart it. Everything ought to be OK now.
• Optionally of course you can also mess around in the CALAMUS.SET file with an ASCII editor and alter the lines RAMforTOS and FastRAMforTOS (Careful: Hexadecimal values with leading $ character!).
