| Extreme Systems impact acclerator card for LC |
Posted by: AlpineRaven on 2016-09-04 07:20:49 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
AP
See attached picture of the card

Posted by: chrisrueckert on 2023-01-14 11:29:36 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. |

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. |

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. |
