My next guess would be the logic board needs a recap...

Just to double check as folks often don't know this but the LC 520's rear power switch being switched on will not start the Mac, you need to also press the power key on a connected ADB keyboard.

It's bridging 16 (Vcc) and 4 (Q0)

At quick glance I see a resistor bodge on my 1994 Thunder/24 card that my 1993 card does not have, on the IC above the 40MHz crystal:

I see the same IC pins bridged on my two working Thunder/24 cards (1993 v2.0.0a and 1994 v3.0.0 ROM versions).

Can't wait to replace the SCA drive in my Quadra 605 with this! ;-)

Great stuff! I see there are other cool improvements in the new "Ultra" hardware design but wondering if performance wise you could expect the same/very similar performance as BlueSCSI v2 with a Pico2 (and with Ultra SCSI Fast20 OverClock) as it uses the same RP2350 chip? Do the SD Card...

I think that might be the same as download #7 here: Macintosh Garden: Power Computing (Mac Clone) System Software https://macintoshgarden.org/apps/power-computing-system-software DL #7: Mac OS 7.6 Part# 1620-0006-00 PowerCenter Pro 180, 210, 240 Does that match the Part# of your CD...

What an awesome Christmas present!

From that Macintosh Portable and PowerBook: ADB Mouse Q & A 3/93 TIL article I took it to mean that the longer plug was to include a "ferrite EMI filter" that was somehow deemed required for low power, and or mobile use "to meet EMC standards". Not sure why those standards are different from the...

I never knew that about these ADB mice, interesting! I have a bunch of them, but none with the 1 inch plug.

I had some similar trouble with the Polar Retro Platinum PLA on my BambuLab A1 mini. I've been successful in my last few prints using the "Generic PLA" profile and slowing down the initial layer print speeds by ~half.

For the 47uf caps in the above mentioned Console5 kit for the SE/30 it contains 20V rated solid tantalums with the exception of c3, c4, c9 and c10 which are 35V* polymer capacitors. From their kit page the change for c3, c4, c9 and c10 is somewhat recent, likely a response to folks (@JDW...)...

Has anyone ever seen video issue exactly like this before? I'm certainly not an expert but I digital pixel wise the image looks correct, i.e. what the logic board is creating/outputting at 512x342 pixels. It looks like some kind of per line jitter in "drawing" to the CRT? That's why I'm guessing...

The "Tantalum" Console5 kit for the SE/30 which the OP said he used includes polymer capacitors for C3, C4, C9, C10. I can confirm since I recently bought this kit. This does seem like its something "analog"...
