So I just got my very own Mac II at home, huzzah!
I transferred several Lightspeed C projects from my Mac Plus
to the II, and tried to open them. I invariably got the
bug box with the message "Memory critical - proceed at your
own risk". The project did not open, but the project file
was busy, and I'd have to reboot before I could access it
again.
Since I initially had only 1 Meg of RAM, the problem seemed
obvious. But after adding a second Meg, the results didn't
change.
In the end, what worked was to start LSC without a project,
create a new project, and load all the old project's files
and libraries by hand. The new project runs like a champ.
(Kudos for your MultiFinder support: turn-around time
is *trivial*!)
So I'm up and running, and this message isn't urgent. But
I'm curious: what went wrong? The old projects were on an
unmodified MacPlus and (non-SCSI) HD20, and were from
LSC 2.01. Uh, I forget which system/finder I was using;
something earlier than 4.2/6.0, no MultiFinder.
The new machine is a stock Mac II, 2 Meg RAM,
40 Meg internal disk, 256 color monitor, running LSC 2.15
(upgraded steadily from 2.01 via the net-published upgrade
kits). The bug manifested under both Finder and MultiFinder 6.0,
under both System 4.2 and 4.3.
My only connection with Think Technologies is as a *highly*
satisfied customer (in spite of the above). Although I am
posting from Apple's Vax, this is a private enquiry,
unconnected with my employment at Apple Computer.

The old projects were on an What probably happened is that you had a MultiFinder partition that was too small for LSC to run well. Some recent articles in this newsgroup mentioned 750K as a good minimum size for healthy running under Multi- Finder. Since the partition size wouldn't change when you added more memory, this was probably your problem. (You change the partition in the "Get Info" box, as I'm sure you're aware.) >kits).

Um, nope - that wasn't it. First, I did try that; second, no changes were made to LSC when I started successfully creating new project files. The problem just about has to be an incompatibility between the 2.01 and the 2.15 project file formats - perhaps something as simple as a missing SIZE resource in the old project files (although I looked for one in the new project files and didn't find one). But back when I upgraded from 1.02 to 2.01, LSC automagically converted the project files very neatly. >>kits).

What a silly mistake! I meant to say, obviously, "under both System 4.2 and the watchful eye of my little puppy." :-) > >Rob Jellinghaus | "And so, whenever you are in trouble, >jellinghaus@yale.edu.UUCP | look to the horizon!
