Computer will boot in a normal amount of time using the Disk Tools disk.
I ordered a new floppy drive from ebay, and.... it has exactly the same issue, so I have to conclude that the issue is not related to the drive as such...
Reading and writing to disks initialized on my other macs (e.g...
I have this weird problem with the disk drive (Sony MPF 42A) in my Performa 475...
Every time I try to initialize an HD floppy disk it fails at the verification step with ''Disk initialization failed because the disk is defective".
When I try to initialize an DD floppy disk it immediately fails...
Maybe a silly question but I noticed that according to the LC service manuals the fan should be installed with the logo side down :
My Performa 475 has a fan installed with the logo (label) side up... which made me doubt on what the the correct airflow direction should be... ?

Unfortunately I don't have a thermal camera, nor do I have a scope (yet).
I have 27C400 EPROM ICs available, and have a programmer to do so (TL866 with adapter)... but I can't seem to find the Lo + Hi bin dumps . I do find single ROM files, the so called old world roms to be used by emulators. Can these be split into two and burned direclty to 27C400 EPROM ICs?
Yes they are a lot of fun :) I honestly think compact macs are very serviceable compared to other computers from the time.
