Hi everyone,
I’m currently restoring a Lisa. So far We have repaired battery damage (corroded traces), rebuilt parts of the power supply (replacing transistors and capacitors), and fixed the video board. The system is now mostly working, but we are currently stuck on the floppy drive.
After cleaning the drive, pressing Apple+2 it now accepts the disk, but immediately ejects it. So I’m unable to verify whether the issue is with the drive itself, the I/O board or with the disks I prepared.
At the moment I’m unsure:
For example, are there any equivalents to something like a test ROM, Eprom, that could help verify if the hardware is working properly?
Also, my machine has ROM version 3A (so it should behave as a Macintosh XL, if I understand correctly). Does this mean it cannot read original Lisa disks and only supports the newer MacintoshXL-formatted ones? I’m not entirely sure about this and would appreciate confirmation.
At this point, I would also consider adding an HDD/SD-based solution instead of relying on floppy disks. Do you have any recommendations for compatible devices or products that work well with this system?
Any suggestions on how to properly test the floppy drive or create compatible disks would be greatly appreciated.
Thanks in advance!

At the moment I’m unsure:
- whether the drive is faulty, or
- the I/O board works
- if I might have created the disks incorrectly
