If you get it to work it should also be good for PowerBook Duos which used the same floppy interface.

The tubes used in the Macs had better specs than TV tubes so the result you have using a b&w tv tube is probably the best you will get. IIRC Adrian’s Digital Basement did a segment on replacing a Mac tube with a green phosphor monitor tube. Looked pretty cool, and the tube has the...

That is funny! I was trying to be humorous, but yes, it was an actual rodent mouse. Unfortunately, the damage to the cable harnesses was quite extensive. I will try to salvage what I can, but I think the machine is beyond my capability to repair, and unless you are local to Portland Maine it...

No mouse but definitely bed and droppings. And residue that’s probably urine. I also discovered through disassembly that my friend had chewed through a bunch of wires both RGB data and high voltage stuff. Way above my pay grade to try to fix. I will probably finish disassembly, clean, and...

I just acquired a Performa 5200 CD. Decent shape, expected brittle plastics, but when I pulled out the logic board it was full of shredded tissue and mouse poop. Beyond the fact that I have to clean and disinfect everything, is it even worth it given this machine’s “road apple” reputation to...

Other than showing some of the similarities/identicalness between the NeXTSTEP and Mac OS versions of Chess, Graphing Calculator, etc. the first interesting ones were the Microsoft Office version X suite and Adobe Photoshop 6/7 (you may need to hunt for the revisions that worked on 10.1).

Do you have a BlueSCSI or other SCSI emulator? Try booting from that to eliminate the HD. I've had long boot times from failing SCSI drives.

@jmacz Do you have an stl for those RAM slot supports? I’ve not seen that before…

I have one of those in multiple pieces in a Ziploc bag somewhere. My goal is to glue it back together, 3D scan it, and have a 3d printable replacement to share. It's way down on the to-do list though :-(

Ok. So, it worked with the original HD (which I managed to find). So I got to thinking that I have not recapped the PS or the analog board yet, and I have some other goodies (Zigzagjoe's 30 Video GS card and PDS 030 Accelerator card) installed. So I grabbed my molex to floppy power cable and...

Looks like it should say "Empty Address" if it's not populated. So I am still looking at the SCSI chip... https://archive.org/details/maxa-snooper-desktop-diagnostics-version-2.0-manual/page/40/mode/2up

Of course there is nothing hooked up to the SCSI bus at the moment.

So, I booted a Snooper rescue disk from a FloppyEMU and ran the SCSI test. Here's what I got

It was working with BlueSCSI until it started giving a Sad Mac. If I remove the card from BlueSCSI or remove the BlueSCSI altogether it does boot from ROM Drive, and from Floppy. I will dig up a real-HD sometime tonight, but something bad on the SCSI bus sounds like the culplrit.

Just a quick note, I did recap the board and cleaned cap goo. Did not note any corrosion, but we all know that’s possible.

Was playing with my SE/30 when I started to get a Sad Mac 0000000F 0000000A. Narrowed it down to my BlueSCSI. If it had a SD card it would go sad Mac. If not I would get the blinking floppy. Tried internal and external BlueSCSI same result. So it sounds like I have a broken trace or something...

That’s normal with that amount of RAM. The boot process does a RAM check. My G3 takes an unsettling amount of time when testing RAM. On the 68k Macs like the SE/30 whose contemporary max was 8MB but with more modern RAM can support up to 128MB, there are ROMs that bypass the RAM checks to...

Did you solve with a bodge wire or did you fix the trace?
