Posted by: Arbee on 2024-08-14 04:42:26Basilisk and Mini vMac hard drive images are not compatible with real hardware because they do not emulate SCSI. They overwrite the driver in the ROM with their own disk code. You can use the Disk Jockey utility on modern macOS or Windows to convert between Basilisk / Mini vMac type images and images compatible with real hardware.

That's odd, I've been freely exchanging disk images between a Basilisk II instance and my SE/30 with a ZuluSCSI without problems.
Posted by: Arbee on 2024-08-14 08:06:10It's one-way: Basilisk can use real hardware images, but images it creates don't have the Apple Partition Map and driver partition and won't work on hardware.

well... For now, it works well. But I even don't know how I fixed it.... I just replace all the parts except CRT, and check it if anything leaks. I found nothing. Then I put them together and determine the voltage of power supply, and all the capacitances. 5V and 12V all works well. Then I just put it and didn't use it for two days, and then it can power on successfully and the floppy icon with question mark appeared, but it read nothing.

Oh! This may cause some problems, but for floppy, I use a software called HFVE(maybe this?) on Windows to write system disk.

Try removing and reinstalling RAM and ROM.
Yeah, I also tried this, I even changed the RAM from 1MB to 4MB and tried to replace some of them to see if the computer can show the correct error. For ROM, I also replaced it.

em.. I can describe it. For CRT, if you restart it quickly, it can show image faster, the reset is that when you restart the normal Macintosh, the image before mouse and floppy icon shown, and it will restart automatically with the speaker made "beep" sounds, just like normal start up. I tried to watch them for about five minutes, and it just reset and reset.
Posted by: dochilli on 2024-08-17 07:00:33HFV Explorer can only write 1.44 MB disks. Are you sure that you have a superdrive in your SE? 800kB disk can not be written with a Windows PC.

Ha? But I can write 800k. And I bought a floppy that works well, it also can't be read....
Did you buy an old Macintosh computer, but it didn’t come with programs and the operating system disks? In this tutorial, we will teach you how to generate them.

Windows PCs can not write 800k disks for a Macintosh!

To write 800k disks in a way to be readable by a Mac, you need the Apple GCR encoding which is not supported on PC floppy drive controllers. You can only write them using the IWM/SWIM chips on vintage Mac or Apple II systems.
Posted by: nathall on 2024-08-21 21:22:24Yes. To be more specific, the Mac drives can vary the speed of the motor depending on what track they’re writing. It’s linear vs. angular velocity. Windows PCs do not physically have the hardware capable of writing DS/DD disks readable on a Mac.

Yeah, thanks. But the thing is I bought a readable floppy from local seller, but it still couldn't work
