Do you have any mods for the portable you would suggest? Thanks!

Alright, I'll try that. Thank you very much.

I couldn't figure out where the volume controls are. Can you maybe show me where? This is technically my first mac experience so I don't know where volume controls are.

if I put a potentiometer on one of the speaker leads would I be able to turn the sound up and down in volume or would it just not work. Or is there a way in system 6.0.8?

https://tinkerdifferent.com/threads/bluescsi-on-macintosh-portable.2764/page-2 @Sideburn Do you remember or know what pin on the portable is 5v for the floppy drive? Can you label it? Thanks!

Also, does anyone know if I can restore the original silicone rollers on the trackball? I don't like the 12 dollar price tag on the ones on ebay.

I did the two diode mods. Here are some photos in case one of you wants to do it. I went to the resistor because there was a steady 5v there. Zener Diode Mod External SCSI Mod

Okay, Thanks!

Would I need them if I were driving a modern lcd with Rezafoulidians design for the external video out?

Thanks very much! Would you need CL1 or M for the display to function normally? Why would they only be on the internal not the external then?

Sorry I thought there was a gerber.

Okay, that is really small. I hope you can fix it.

Can you use a tap and die set?

Also, what type of connector is the display connector on the board? Does anyone know?

Is M supposed to do anything? I dont think it's connected to anything.

Do you know the difference between cl1 and cl2 on the schematic?

Ah okay! Thank you very much! I just got my portable working and I am waiting to put it back together until I can do the 2 diode mods, (waiting for shipping is a bear.) So I was just thinking of trying to take a portable video adapter and adapting it to the display connector on the inside. For...

Thanks! And I found that the J stands for the plug and pin, but I don't quite understand what the parenthesis on the end of the net stands for do you know what it means?

Does anyone know if there is a difference between FPDATAI and FPDATAX nets in the portable video outs in the schematic?

Don't know if it's needed but I found this if you need a reloaded board. I am still hoping you can fix yours. https://tinkerdifferent.com/threads/logic-board-macintosh-classic-reloaded.26/page-2
