This is an unfinished, but totally playable, development version of the game "Mouse Stampede" for the original Macintosh. It was the first 3rd party Macintosh game ever created.

I rescued this from a disk labeled "Games" that came with a cache of about 10 400k MFS diskettes filled with very early Macintosh software, that were claimed to have come from Apple and the Macintosh project. The person I got the disks (and the Macintosh SE) from, said that their spouse worked as a programmer in the early 80s at Apple on the Macintosh project. This seems to be somewhat likely as most of the programs on the relevant disks have date stamps of 1984, and some even have date stamps of December 1983.

More information here:

This appears to be the lost, original 1984 version of the game that was in circulation in the mid to late 1980s. I have not seen it or found it on any other website distributing 68k Macintosh software.

Gameplay wise, it is essentially a clone of Centipede with some great sound effects and extra features. You are the 'mouse' (literally an icon of a computer mouse) at the bottom of the field. It gets very difficult very fast. Shoot any turtles you see in later levels to slow down time temporarily, that helps. Solid cheese cannot be shot or broken. The shopping cart wave, they drop more cheese onto the field for you to have to shoot through so get rid of as many carts as possible.

If going for a high score, after you clear 20000, 40000, 60000, 80000, 100000 points (and so on) you can start a new game at a "higher" starting score by clicking the dialog when starting a new game. This serves almost as stages or difficulty levels. After 100k points it lets you start at 90000 from the beginning and gets brutally difficult, but I found this out on the finished Mouse Stampede 2.0 version, so I have no idea how much of that was coded in this one. The scoring guide is in one of the images (screen from the later version): this is from the finished version. Shoot paintbrushes, flies, knives, and the shoe for the most points. Some tips: stay towards the center of the field often, as bats are huge and always spawn on the sides. Also, clear the mice in early stages immediately, by simply spam clicking and shooting them from the very bottom of the field as they charge straight down at you. On any minimum score game, flies and other high point value enemies don't tend to appear until you clear all the mice around 3-4 times, so doing this asap allows for higher scores as you can then kill high point value enemies on the next wave of mice over and over while leaving one or two leader mice (gray shaded) alive.

If you like this please comment, rate, upvote so it gets the attention it deserves, as well as the rest of the weird apps on these ancient diskettes I saved! Thank you very much!

See my profile here for more info about the diskettes I have.

Architecture: 68k

System 1.0, 1.1g- System 6.0.8 and possibly later- needs more testing- it works perfectly fine running off a 6.0.8 .dsk hardfile of 500MB that I use on my FloppyEmu (even seems to work fine under 6.0.8 MultiFinder with After Dark and other inits), but I would not advise this: get Mouse Stampede 2.0 instead, especially on a real Mac w/ a later OS. Upon quitting the game, the disk ejects and the machine resets so running it on a real hard disk may damage data. I am unsure of this and have my .dsk hardfile backed up anyway but other users without an SD device and backups, *proceed with caution*.

Because the game draws to the whole screen, it is recommended to disable After Dark 2.0 completely: or at least, disable its "screen corners" feature. While playing the finished 2.0 version, I had issues with the game "losing focus" as we say now, that is, upon moving the mouse to the far bottom right or left of the playfield, After Dark would come on then immediately turn off and I'd see my open windows in Finder temporarily, but continuing to click and move the mouse would cause the game to be the top application in focus again. However, stuff would be missing from the playfield, mostly cheese. The game redraws the screen in full very often: after shooting certain enemies and after killing every mouse on screen, and when it would, it would redraw everything that wasn't visible (mostly cheese) because of the conflict with After Dark. I was also using Multifinder, but I figured I'd add this. For either version of the game I would recommend disabling After Dark screen corners. This was tested on my Macintosh SE.

Added image file. DiskCopy 4.2 if you want to write it to a real blank disk (400K) and use it on a real machine.

It may need to be renamed from .img to .image

Nice upload! And yes, DiskCopy 4.2 images are always most welcome. Smile
