General Computer Hypercharger 020 Manual

#1 Mon, 18 May 2015 - 22:29 68kMLA

I have a Mac SE I picked up a while ago with a General Computer Hypercharger 020 however I haven't been able to find anything saying what the jumpers are for or what the 50 pin header on the back connects to.

While I managed to find the extension for it, I have not been able to find what the jumpers do, less yet a manual. Does anyone have any idea where I might be able to track down a manual or guide for it?

Googling about I found the drivers, probably like you did on the Vintage Apple Drivers website.

But I also found a link to this forum of a Mac 512K using the same accelerator. The 50 pin head goes to a Kelly clip that goes to the 68K CPU on the 512K Board. Links to to pictures of the owner's board though flickr.com

No luck on finding a manual - yet.

Not quite the same. Hyperdrive's an adapter to add a hard drive to a 512 whereas the Hypercharger plugs into the SE's PDS slot and basically replaces it with the 68020.

I can't find it either.

Would be nice if there was a Macintosh Garden equivalent for manuals.

Maybe it's on Bitsavers - I know they have a lot of datasheets for old chips, maybe they'll have some for Mac accelerators.
