| General Computer Hypercharger 020 Manual | |
| Posted by: Compgeke on 2015-05-18 14:29:43 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? | |
| Posted by: Elfen on 2015-05-18 20:49:55 Googling about I found the drivers, probably like you did on the Vintage Apple Drivers website. http://www.vintageapple.org/macdrivers/accel.shtml 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 https://68kmla.org/forums/index.php?/topic/503-gcc-hyperdrive-20-in-mac-512k-photos/ No luck on finding a manual - yet. | |

| Posted by: bredfrown on 2023-04-18 06:55:15 I know this is a dead thread, but I thought I'd bring it back to ask if any folks here ever had any luck getting the RAM on this accelerator to work? I've got a new thread covering what I've done so far, but I'm stuck at trying to get this accelerator to use its RM (and copy the SE's ROM into RAM) over the SE's. Macintosh SE and a HyperCharger '020 AcceleratorSo... I did what I've been doing for a lot of accelerators, I dug up some contact names and went on linkedIn. I Just sent a message to Kevin Curran, let's hope for a repeat of my success with Lincoln from NewLife. "GCC was founded in 1981 during the onset of the video game craze. C.E.O. Kevin...
