se/30

Hi all, Apologies if this is the wrong forum for this topic or if there is a topics already around this, I'm a newbie! I have a Macintosh SE/30 with a Blue SCSI v2 with Pico W installed. Everything works great, except for internet. I have followed the instructions from the Blue SCSI website to...

I've spent the last two months working like mad on a comparison of the new (July 2024) Baby Face Electronics Power Supply, comparing it to my stock recapped SONY PSU and also to the SEASONIC PSU that I've been using since 2018. I also successfully tried the 16AWG wire recommendation by...

I created this side-by-side pinout diagram back when I accidentally connected my Daystar Turbo040 accelerator (intended for a Cache Slot) into the PDS pass-thru slot of my TS Adapter, installed in my SE/30. That resulted in one of the ASICs getting fried on the Turbo040 (it was later repaired...

Folks, which of the following two wire harnesses have a thicker wire gauge? (I know the answer already, BTW.)

Howdy Folks, So my resurrected battery bombed SE/30 continues to have BlueSCSI issues but after reflowing the SCSI chip it got a little...better? betterish? So here are the symptoms: With the caymac BMOW rom installed If I try to boot the external BlueSCSI from a cold boot it tries to boot disk...

I've been working on four SE/30 boards now for on and off for a few months just whenever I have a couple hours to spare. Well Tonight I had a HUGE win on the most damaged board I've been working on which you can see here: I would have live streamed it but my overhead light burnt out today...

Hey Folks, After troubleshooting on and off for a couple weeks I've managed to get my first SE/30 working :) As it turns out though that one was the easy one! I've got a second board here that's exhibiting some strange behaviour depending on whether I'm using the original rom sim or if I'm...

Greetings, Wondering if someone can help me to replace the Y3 Crystal one of my three broken SE/30 boards I'm trying to repair. Afraid that the legs just couldn't take an ultrasonic cleaning and broke off right at the base; I tried replacing it with one of these...

SE/30 owners, if you have a BlueSCSI v2, could you please run MacBench 3.0 "All Disk Tests" and post your scores? (Please use only MacBench and only version 3.0.) I'm seeing seriously sluggish BSv2 performance in MacBench 3.0 on my SE/30 (with or without accelerators), despite the fact that...

Hey everyone! I'm having a very difficult time with a BlueSCSI v2 (with Pico-W) I got from Joe's Computer Museum a few months ago which I'm only now having time to set up. I've installed it into my SE/30 in place of a SCSI2SD v5.2 which was in there previously. This is my first BlueSCSI product...

I have been questing for a SE/30 for many years. I now have one, and have been looking around online and see the incredible skills being put to good use with ROM swaps. Recapping the motherboard to making upgrade cards (last I checked, that was the realm of Big Tech). I would really appreciate...

TLDR: Analog board adjustment has been made to no avail, compressed picture persists across multiple known good analog boards that show full picture with other logic boards. Confirming problem is on the logic board). I recently picked up an SE/30 for a steal but it had a Simasimac screen with...

Why? To hear the miniscribe sounds while I use my blueScsi wtf? My miniscribe never worked and I gave up on it, so I figured I’d try to drive the stepper motor with some modern circuitry with the hope being that one day I could signal it by the activity indicator on a blueSCSI. how’s it going...

Folks, I discovered something new with my SE/30 & FloppyEMU last night. I reported it to Steve Chamberlin of BMOW, and he kindly wrote back with the answer. I thought it might be a situation where some of you vintage Mac hackers might get some kicks out of this. BACKGROUND As you know, the...

Hi all! I am working on restoring my first classic Mac, an SE/30. I've started to dive in and have ordered capacitors and such, cleaned it, taken out the PRAM battery, et cetera. I powered it up after giving it a good cleaning and got a relatively dim vertical line. Page 162 of Dead Mac Scrolls...

Hey all, hoping someone can give me a bit of a steer on a problem I am trying to solve with an SE/30 I picked up last week. The logic board itself thankfully had a non-leaking original battery installed which I was relieved about - but the capacitors had done some pretty serious leaking, and...

I picked up a SE/30 that had some pretty significant capacitor leak damage. I had a transistor at Q3 fall off the board from corrosion. I didn't initially see it, but I had pin rot on UE8 that lead to a jail bar pattern on the screen. I replaced Q3, and installed a brand new UE8, and the...

I picked up a SE/30 off FB MArketplace and in the picture it had the vertical lines and a floppy (interestingly the bars were only on the background - the floppy icon was in tact: But, it's an SE/30, so I figured its is worth trying to fix. I got it home and fortunately, the battery was...

According to this LEM page, unless you are installing 17MB, you should be putting the larger sized SIMMs into Bank A, with the smaller sized SIMMs into Bank B. However, when I put four 16MB SIMMs into Bank A, and nothing in Bank B, I get death chimes and a crazy display. But if then put 4...

Introduction So I’ve bought a known defect SE/30. I got it for about €70 with the carrying bag, some documentation and original (and blank) floppies. An over all OK deal. It was known from the listing that the screen was black. When I started the computer for the first time the screen was black...
