This is probably an easy question to answer, but not being an Atari Guru . . . I have a 520STfm, which I have upgraded to 2.5 M with the Z-ram board, and Samsung 80 ns 1 megabit chips (it is the 3-D board and eventually I want to put the other 2 megs in). It seems to work all right, and the z-ram Ram test program passes the memory, but I have some software problems. There are several programs which fail to work, unless I use E-disk (the Ram Disk program) to create a 2 M ram disk which effectively gets rid of my upgrade. 1. The Note Wizard, Scale Master, Chord Magic and Rhythm Time programs from MIDImouse magic refuse to run at all. 2. Drachen (the public domain Mah Jung game) runs for a while, and then gives me 4 or so bombs. 3. El-Cal, a mathematics program, runs, but gives problems with window and memory management. All of these problems go away if I mask out the new memory, but this is a stop- gap solution. Does anybody have any ideas? I have considered putting Tweak on the MMU, board and Video Shifter contacts, and replacing the contacts, but this problem seems might intermittent for such problems. If anybods has any ideas, please E-mail them. Matt Asplund asplundm@vanlab.byu.edu Replace this line with your message (press CTRL U first)
