Thanks. I found them also and they are close to me in Miami so will be easy to get and ship to Cayman Islands. Just need bunch other items also like the 1N4150 and the BU406.

This how the unit came. The battery still behind it. But I have no battery in it.

Here some pics.

On my plus I added the resistor for it to work. I have recapped the analog board but it’s the flyback had that bad smell of dryer or ozone after a few minutes on and I get no picture. I get the chime but screen black and no current comes out of the flyback. There is no discharge spark after it...

So I tested blueSCSI with the MaSnap scsi and at first, would not work. Added an external usb power to the blue pill and it now boots up fine. Will need to try some more things with it. So I have a 512Ke with MacSnap, Plus 128K ROMs V2 1mb Ram and a 400/800K floppy in it. Nice. I have another...

No chime at all.

I solved the power issue by changing the opto chip. But now I have a tight vertical bars issue and this after a full recap of both boards. Anyone have ideas?

Kai or others. I have a classic II giving me tight format jail bars. Board is recapped and so is analog. Voltages are good. I have removed and cleaned below, pads and chips for 2 of the 4 memory, audio and edge. All areas prone to damage and all looked very good. Still have bars. Any suggestions...

I will give this a try and provide an update. Working on another item at the moment.

Eric does the blueSCSI work with MacSnap scsi? I got a 512K unit today with this in it with the Plus ROMS as needed. Tried it but it would not boot up. All I got was the red light on the blue active. thanks

I just got a 512K with the MacSnap and SCSI adapter in it. It powers on and all and I see blueSCSI has power as the red light is on. It does not boot from it. I have not looked into this at all so putting it out there see what others know or can say.

Anyone have any more ideas on this? I am stuck on it.

The issue is solved by replacing Q101 and Q102 transistores. This after a full recap was also done.

Mine Classic II also. My error. I been reading up on this and find the same to replace the mosfet at QP2, the TDA4605 at IP1 and optocoupler ar QP1. I am not sure on which diodes to replace. I have read people change DP12, 2, 5, 7. Now I just need find these parts from used items I have here.

I am working on a classic II and have read over the posts here. Not able to determine what could be the issues on areas to check and what to change but I am not getting correct voltages from the analog board. It’s fully recapped. I am getting 10.28 instead of the 12 range. And for the 5v I am...

Got it. Easy enough. To the connector anchor point to ground.

So on the internal scsi connector says all odd pins are ground? Just want to confirm to be sure? Is there a closer location you would suggest so I not need to run a long wire on board underside?

Don’t know. i Have a new holder to install and it won’t hold solder. I tried. I am sure negative has to go to ground somewhere why I asking about a wire run to another connecting point.

Here are the images

When removing the battery holder, the negative side via completely came out. On either side of the board there is no visible trace of where it goes to put a trace repair or wire. I assume it’s inside the board so i can’t do much with it. Is there a contact point somewhere on the board I can run...
