Extreme Systems impact acclerator card for LC

[AlpineRaven]

Good morning, 

I have an Extreme Systems Impact accelerator card for LC which I am very keen to use in Macintosh Classic.

I dont have the drivers for it, I tried downloading this file from;

http://vintageapple.org/macdrivers/accel.shtml

down to;

Extreme Systems

• Impact and Extender v1.22 (29 k)
• Drivers for the Extreme Systems Impact and Extender 030 accelerator boards for the LC 1 and 2.

Each time I try download Impact and Extender v1.22, Stuffit cannot open that file at all. (I was using Version 11 in OSX and 6 in classic) - its not recognised file.

Thank you
Cheers

How are you going to use a LC card in a Macintosh Classic ?

PDS slot? It does work in Mac CC as well

Ah ok, your first post didn't say Color

Any chance that anyone can get the original file to work? Just dropped a new hard drive in my color classic and also am not able to unstuff that file with any version I've tried.

Any one have the aforementioned Software? Every site I download it from seems to be same corrupt .sit file that can't be uncompressed.

I have just received a CC with the accelerator card and will backup the system folder. Once that's done I'll post the files I suspect to enable the accelerator on Macintosh Garden.

Excellent news make sure you compress it in a way that preserves the resource fork!

So either Stuffit 5 or later (but not sitx), or wrapped in a mac binary or hqx or similar. Stuffit 4 and older files have a resource fork and get corrupted when you upload them. Shout if you need any advice, forgive me if this is all old news to you.

Here's the control panel. I suspect this is what activates the accelerator. Let me know if it works.
