Since so many people were kind enough to answer my plea for help I thought I would post an update. I did some experiments: My system is a 1040ST (really new), SM124 monitor, and a SH204 hard drive. Experiment 1: I disconnected the hard drive and installed MWC for a single double-sided system. This worked just fine. No problems. Experiment 2: Reconnect the hard disk, but continue to use only the ram disk and floppy. No problems. Experiment 3: I used the hard disk in the following trials (the table indicates the location of the specified entity): Trial 1 Trial 2 Trial 3 Trial 4 C compiler and floppy hard disk floppy floppy libraries Temporary files hard disk ram disk ram disk hard disk Source ram disk ram disk hard disk hard disk --------------------------------------------- Results of trial: worked bombed worked worked I'm going to experiment further. I'd be interested in hearing the opinion of Atari. What part of my system is failing? "Thank you for your support." ---Bob Amstadt bob@wiley.uucp {csvax.caltech.edu,trwrb.uucp}!wiley!bob

I have tried this configuration and it works fine for me. I should
qualify this by saying, I've tried it with MWC version 1.2, using
an older 1040ST, SH204, and the Bob Locanto RAM disk configured
for 512K. I have not tried it with the newer MWC version 2.0.

You didn't say how large a program you were compiling or how big your ramdisk was. Many people are suprised to discover just how much room is necessary for temporary files even on small programs.... --- John Stanley (john@viper.UUCP) Software Consultant - DynaSoft Systems UUCP: ...{amdahl,ihnp4,rutgers}!{meccts,dayton}!viper!john

I use MWC with the following configuration all the time: Compiler/Libraries: Hard disk Source and final code: ram disk Temporary files: ram disk I use a 400K ram disk, and compile programs like HDSCAN (1800 lines of code, 46K executable) with no trouble. I have had problems using a 512K ram disk (even though my program will compile on a 512K system fine!) I also have Megamax 2.0, but still prefer MWC 2.0 for some bizarre reason (probably the better docs). -Todd Burkey ...ihnp4!meccts!zeke!stag!trb

This weekend I was able to try my hard disk and compiler with a different 1040ST. Guess what! The compiler ran flawlessly. Unfortunately, this does not tell me why the compiler dies on my system when everything else SEEMS to run fine. So this is a plea for diagnostic software. Has anyone seen software written for the specific purpose exercising the computer? I'd write my own, but I'm a little upset with my machine. ---Bob Amstadt bob@wiley.uucp {csvax.caltech.edu,trwrb.uucp}!wiley!bob
