A2630 accelerator - 040 upgrade possible?
« on: December 04, 2010, 11:01:08 PM »
The title pretty much says it all. I rescued a 68LC040 (ceramic PGA version) from a junker Mac at the recycle center yesterday, and I'm wondering if there's a simple adapter to use it in place of the 030 (also a PGA, but fewer pins) on my A2630 accelerator board. Does anybody have any information on this?

Okay, thanks. Guess I'd be better off seeing if I can get an 040 accelerator cheaper without the processor...

Yeah, I know the LC doesn't have the FPU, but it would've been nice to be able to put it to use - no sense saving it from the scrapyard just to have it sit around taking up space. (And even without the FPU, I'm guessing the massive cache increase and longer pipeline make a pretty noticeable difference!) Maybe I'll hang onto it for when I finally get around to a homebrew computer project like I've been wanting to do...

Well, I'm not desperately in need of it at the moment, but I'll keep that in mind. Thanks!
