I'm not sure if this post belongs here in the collectors section, audio section, or console games to be honest.

I own a PowerBook 1400c with floppy and CD drives soley for the purpose of software transfer from my macbook to my old 512k Macintosh. Because of this, I've never really needed it to do much other than read and write.

This week though I thought it would be fun to use it in a final presentation we are having tomorrow for our game history class. My group and I were assigned to do a research project on "The Secret of Monkey Island." We've been playing the special edition version for modern systems, but I discovered the original used to run on MacOS 7-9, so I decided to give it a whirl on the powerbook, which runs 8.1.

I brought the game over via a blank CD ROM burned on my macbook. (My Macbook crapped out during the final moments of the burn, but I doubt it was too detrimental to the data since it was just finishing up?) The game booted up, lagged incessantly, and crashed the entire system nearly every time I tried to play. I figured the computer was just old, but as I continued to root around the system, I noticed that the whole system was having huge issues regarding RAM, and later found out via settings that there was no RAM disk attached.

I was going to give up on the game but this morning just out fo curiosity I cracked the computer open to get a closer look at the RAM cards to see if they were damaged. To my surprise, the upgradable RAM had actually fallen OFF of the board and was sitting loose on top of its connector. I reattached it and booted up once more and found that the RAM disk was now working. This eliminated the lag from the game!! However it still crashed in either the final moments of the opening screen or the exact first second of the following scene.

I was a little miffed, but after observing it crash over and over again, I deemed it to be an issue with the MIDI(?) sound track playback. I turned the music quality down in settings, and the game suddenly became playable. It sounds horrible, but it will do for our presentation!

I have far more than what the basic requirements to run the game at this point, so I feel like this shouldn't be an issue, and I'm very interested in finding out what the problem here is because the soundtrack is pretty great!

I also want to note that the game performance SERIOUSLY drops if I am not CONSTANTLY giving input to the computer? For example, the first scene takes FOREVER to get through unless I am constantly moving the cursor around the screen.

Does anyone have any idea why that would be or if its some kind of power save setting?

And most importantly, does anyone have anymore knowledge about the sound system this computer uses than I do?

Try turning virtual memory off; Full Throttle (also from LucasArts) had weird issues with VM enabled so I wonder whether it's the same issue.

i was hopeful, but shutting the virtual memory off did nothing to help the game along, unfortunately. :(

Thank you for the tip!

Have a look in the "Powerbook" control panel for processor cycling and speed settings.

"Processor Cycling" should be turned off. Not sure if this control panel has SEPARATE settings for battery vs AC power.

For whatever reason Apple really took it upon themselves to hide the processor cycling option as well as possible in 8.1, quite the trick to get it to show up! :eek:

I'll keep messing with this one, but for now, it does not seem like that helps the crashing, though it DOES fix the issue of game performance tanking if im not constantly clicking/typing/etc!!

It may not be important info, but I feel like I should note that like most old laptops, the battery is totally dry and cant hold a charge at all. This makes saving settings a little tricky considering theres no charge to keep my settings saved over anywhere longer than five minutes without power.

Thanks for the info about the processor!!

Depending on how the CD is formatted, you might want to try copying it's entire contents to the hard drive - if anything, it will prove whether the CD drive can read the content of the disk.

Most very old games required something like Quicktime 2.5 as a minimum, but putting that on 8.1 is NOT something you should do.

However, it might be an idea to 'upgrade' 8.1's Quicktime to something like v4.0.3
