Looking at this: http://hackaday.com/2016/08/22/ask-hackaday-calling-all-68k-experts/
I'm wondering if there's just a set of jumpers telling the Mac to look for an FPU or not...
But I can't find pictures of the back of a 550c card to check if what look like jumpers between the LSI chip and the connector are indeed jumpers, and whether they should be set differently if they are. The 540c card seems to have all three unpopulated. (R700/701/702, see 00:30: https://youtu.be/82OkgLW_lnY?t=30s )
Can anyone take a scan/photo of a 550c CPU card to confirm/deny this?
Thanks!
Adam
