right now, it's just a concept, I need people behind this to work, I need someone to program an FPGA as the MMU, design the control panel from scratch, and design the PCB for everything

I've been developing a concept that combines the hardware legacy of the original Macintosh with the flexibility of the Sega Genesis. The goal is to create a cartridge-based add-on for the Genesis that effectively transforms it into a Macintosh Plus clone while still allowing for normal Genesis...

yes I do, is the logic board for an SE SuperDrive/FDHD or an SE/30? If it's for a regular SE, I don't have any double density floppy drives, much less double density disks. Shall we move this to DMs?

I just got an SE SuperDrive from someone who said the case was broken, and it was very much unrepairable, I really should get a maceffects case for it, and a logic board because it didn't come with one

It would need to have daisy chaining compatability, so thing with only one firewire port can plug into multiple things if need be. Plus, firewire drives rarely fail so there's no need for one now

although, maybe capacitors are bad? Has the power supply been recapped?

there is a new board that uses switch mode supplies to generate the voltages needed

you can test it with a multimeter in resistance mode or an LCR meter in inductance. if it shows as open circuit on either the primary or secondary, the transformer's done for. Has the power supply been recapped?

if a capacitor came off, DO NOT RUN IT, get it recapped as soon as possible

either something's shorted or the transformer blew open, do you hear any clicking or high pitched noises? If your ears aren't sensitive to high pitched noises, there are apps you can get for iPhone and Android that are spectrum analyzers

SE/30s are picky about their RAM, so it's just a matter of trial and error to see what works, and for the memory, the ROMinator is slightly thinner and a standard ROM SIMM, I know BMOW said there was a way to make it work in another forum post, but it has escaped my memory

I bet you they implemented that because someone torched their adapter for a warranty claim

there are IDE to SATA adapters which you can use

I usually check sites like ebay or mercari, but I have a few machines i got locally

any time, enjoy that Macintosh Classic! I used to own one, but I hated how slow it was on system 7.5 and was too stubborn to put it back to 7.1 or earlier, so I'm keeping my eyes peeled for a Classic II
