[comp.sys.mac.comm] memory problems with accelerator

riddle@mathcs.emory.edu (Larry Riddle) (10/10/90)

I recently purchased a Mobius One Page Display monitor for my SE. The
display for the SE includes a built-in accelerator that doubles the
Mac's speed. I have been having trouble with VersaTerm when using the
accelerator (and possibly other programs, but VersaTerm is the one I am
positive has a problem with the accelerator.)

I have 4 megs in the SE, am running System 6.0.4 with a 60 meg CMS hard
drive partitioned into three partitions using MultiDisk.  When running
Versaterm I reach a point where if I try to access a menu item, such as
when I quit, I get either a message "There is not enough memory to
complete that operation" and the program quits, or I get a "application
unexpectedly quit" message (under multifinder). If I am running under 
just the finder, I get a system bomb with ID=15. If I start the program
and quit shortly thereafter, everything works normally.

I have increased the multifinder memory allocation for VersaTerm from
the recommended 369K to 500K. The manual says that 369K should suffice
for all Mac's through the MacII with a 19'' color monitor.

So, there must be some conflict between the accelerator and VersaTerm?
But if I boot the SE from a floppy containing the accelerator and
monitor init and run VersaTerm from a floppy, by-passing the system
folder on the hard drive, I have absolutely no problems and no crashes.

I have turned off all inits using InitCdev except the accelerator and
monitor inits and the DeskTop manager, and still get memory crashes
running VersaTerm. I put the DeskTop manager on the floppy system -
VersaTerm ran fine off the floppy set up. I have tried to test as many
init conflicts as I can with no positive results. I have renamed the
accelerator init so that it is the first one loaded. Didn't help.

I am stuck on what might be causing these memory problems. Does anyone
know what might cause these error messages? What is error ID=15?
Any suggestions at all? I can turn off the accelerator, of course, but
at this point I am extremely curious to understand this problem, and
extremely frustrated. Any help would be most appreciated. Thank you.
