Does your SE reloaded build not require UC12/UB12 ? I don't see any mention of those chips - the SN75175 chips brought up in the first post of this thread. Thanks!

@Kai Robinson I came across this thread while looking for replacement SN75175 for my SE/30 Reading the data sheet, it looks like SN75175DR is the same chip, only packaged in tape & reel? It looks like only the tube packaged part was made obsolete. Am I wrong? This is only the 2nd time I've...

@Mk.558 I don't see a signature on your post, do you have a link you can share? Thanks!

@craig I am also curious where you got the Saronix 33.342 MHz oscillator - I can't find an equivalent part in that kind of through-hole package to repair an SE/30. Thanks!

I have a few 1.44MB floppy drives (all from SE/30s) that I would like to recap. I noticed the video from @JDW about this subject, but in the linked cart one of the capacitors is discontinued. I'm unsure what to replace it with that has a similar footprint/values/etc - anyone have an updated...

There are other methods, like using this utility to copy files from the sd card onto the hard drive image itself: https://bluescsi.com/docs/Toolbox#utilities I'm not sure what version of the bluescsi that is? I'm not a bluescsi expert. I"ve not seen one with that square cutout in the PCB...

There are also various facebook for sale groups, I saw this post just today but its local pickup only in Minneapolis. I've acquired three SE/30s off of facebook marketplace within <1 hour drive of my house.

This guy does what you are looking for, he's located in Chicago. I would email him saying what you are looking for: https://bonuslifecomputers.com/

I revived another drive recently (also Quantum SCSI from a mac, but a ProDrive LPS) that wouldn't spin after just gently moving the platters and heads myself which got things unstuck. But I did so connected to a bluescsi in initiator mode so I could immediately image the drive.

I had the same model ProDrive on my SE/30 and it suddenly came to life when I placed the drive on its side. I wrote about my successful efforts on this other forum, with the help of a BlueSCSI v2 in Initiator mode in order to make an image of the old drive...

I am a classic mac newb, but I do know the Floppy Emu can emulate an "HD20" device - a hard drive apple made that connected to the external floppy port. But wikipedia says this: https://en.wikipedia.org/wiki/Hard_Disk_20 So maybe your IIx doesn't even have HD20 support in its ROM? I bought a...

I watched a great video on this topic earlier today. The focus is on missing pads for capacitors locations on Mac logic boards:

I stumbled across this item for sale that looked interesting - can't find any mention of it in the usual forums or facebook groups: https://jcm-1.com/product/macse30-peeker-v4-5/ Both of my SE/30s work, but I kinda want one just to be mesmerized by the blinkenlights! I like the ground...

I noticed in @GutBomb's latest video, he mentions powering up an LC II after removing all surface mount electrolytic capacitors: link should go right to that point of the video

Hello! How do you mount DSK images on real hardware? I transfer them via BlueSCSI Transfer Utility onto my mac. I am running System 7.0.1 on an SE/30. I never used a classic mac back in the day so this is all new to me. The BlueSCSI Bootstrap disk image has some utilities in the Stuff ->...
