Report Upgrading a Macintosh Portable to use a 68030... maybe it can be done? in 68k PowerBook Posted Wednesday at 05:41 PM On 6/20/2021 at 2:18 PM, portableleo said: After some reading on the forums it looks like TechKnight got much further than me. Too bad the project seems to be on hold... maybe time to revisit it if there is enough interest? Yeah, but not far enough. This just takes more power than the feeble old portable can give. I think you would be far better off with an FPGA-based project, or use one of those Amiga soft-core type CPUs like the raspberry pi which emulates a 68K.
