Thanks I want to add a picture of the 2. On left is the 800K one printed from the file here. On right is the 2mb drive version.

I am hunting for the file to print the 2mb floppy version which is a bit smaller. The main gear, the top smaller gear and the shaft opening all need to be 1mm smaller. For the other floppy drives this works great and I already printed and using a bunch of them. @Drake are you able to assist any...

Is there a file to print my own for the 2mb floppy? The Sony MP-F75W-12G. There seems to be a 1mm difference for the main gear diameter and the upper smaller gear. The shaft is also smaller at 1mm. I guess could scale this one down to fit? Sorry I am asking as i am new to 3D printing.

Thanks. Your teachings and those of @Mac84 @Branchus gave me the guidance and will to find it. Many more to come.

Today I spend the day checking traces again using the schematic and going chip by chip. I had a feeling it was scsi related to I started there on the scsi/scc/via chip going to the others. I came to pin 64 that goes to 125 on the eagle chip. This trace is for the CE1 that is needed to enable the...

Now I am shocked. I made floppies for 7.0.1 and boot from that to install onto the HD. Well it also freezes on the welcome screen. This can be 1 of 3 things. Bad scsi stiuff. Bad hard drive. Bad rom.

What has worked. Boot recovery on blueSCSI. Formar hard drive. Copy the needed files from recovery to hard drive. The system folder and all the other needed items to boot. Any install I do does not work.

I did partían for the entire drive. I used to windows old days needing to do that first then formar and install. I use the entire drive for the OS.

This a Classic II.

All day I have been working to find out why the Classic II won’t boot up to OS. Loads and then freezes on welcome screen. BUT if I load the system recovery disk image with my external blueSCSI it boots up fine. I went as far as partition format and install 7.1.1 on the internal hard drive with...

The reset trace is connected which allows the board to chime and come up. Before connecting this, I had nothing but a tight vertical bars in center of screen and no chime. i have redone the solder connections for U12/15. The scratches are surface with good continuity on the trace still. will...

Here some better.

Here are some pics. Also showing the screen. The memory spot I don’t have a picture for right now. This one in the area of the battery that was removed. It was very clean there so I was surprised to find damage there.

Well now that I have the chime and happy face after a trace repair of pin 15 egret reset and pin 5 on U14 memory 5v missing. It will start the boot get to the welcome screen and lockup. Stays there. Anyone have any ideas what to check, try etc?

This issue is now resolved. Turned out not to be the ROM. EGRET chip pin 15 trace that is the RESET was broken in the battery area. Was very hard to find and was I was checking each chip and each pin traces for continuity, I found this. Repairing this gave me the chime but bad memory sound...

I am hearing some talk that a LC II rom could work in a classic II. Can anyone here confirm or comment on this?

Yes so true. I sure it has to do with PSU as other has said. I don’t have a Quadra unit yet to see. I have Mac II, LC I and II, Performa 6200CD, I have a Centris 610 on way so not sure what that has.

I could be wrong. On the PSU I have it looks like this. The clip.

Clíp for the cables coming out out the power supply. If I recall, the Mac II has it on the Sony CR45 PSU.

After cleaning my IIc board, I get this issue. I swapped the rom, cpu, mmu, iou from this board to another and it all works. The issue is related to this board and/or items on the board. I don’t get to test screen. It worked before the good cleaning. First time with brush and IPA only delicate...
