In case you didn’t know about it already, the schematics for the SE/30 logic board have been redrawn using modern software! Get them on github. They may be useful for troubleshooting…

I don’t think it’s really harmful to run it, C5 is part of the audio circuitry, so you just won’t have sound. The problem is not the missing capacitor, but the leaked electrolyte from failing capacitors that is eating, and thus destroying, the circuit board. So better remove the remaining...

It seems that comm slot ethernet cards are getting rarer and rarer, specially comm slot 1 cards! So, I was quite glad to find one, at a relatively reasonable price… Here are a few photos, as this card seems to not be very well documented: Did I buy a dusty, rusty, very yellowed Performa...

Thanks for the detailed answer! I took a look on eBay, those are quite expensive upgrades!

Is there any CPU upgrade that won’t need an interposer? (I want to keep it simple!)

Found locally (extreme patience is key!), it’s in very good shape and I only paid 10 euros for it !!! It’s a 21 inches consumer TV (model number is KV-21C5B), with two SCART inputs (we call them Péritel in France) so it accepts RGB signals natively! Not a huge TV but its size (and weight!) is...

Will this 486 DX4 100 work with the DOS card?

You could ask on the Classic Mac section of the forum of the french site MacGeneration.

Did you finally found a working SIMM for the DOS compatibility card? I just got a Performa 630 DOS Compatible (I believe the hardware is the same as the 640CD) and I too have a SIMM that prevent the PC from booting (same symptom: black screen). I tested that (32MB) SIMM on the Mac side of the...

Do you still have analog TV in the US? Here in France (and pretty much everywhere in Europe?) analog TV broadcast has been discontinued like 15 or 20 years ago! So, losing the TV tuner is not that a big deal! One thing very cool would be that an electronics wizard develops a drop-in digital TV...

Just a though: they were linux distros for PowerPC Macs back in the day when this monitor was current. So, if this monitor was (still is?) supported by linux distros, all the information on how to initialize it and how to set it up (geometry settings are done in software), all is in the linux...

Beware that the port has to fit physically in the keyboard enclosure. And it’s a tight fit, better check out all the dimensions! (I once "borrowed" an ADB port from a 6200 motherboard to repair an AEK II, I was able to solder it just fine but it didn’t fit at all)

Or just buy an IDE SSD, they’re expensive, but maybe less than trying a whole bunch of adapters?

AdaFruit has USB hub breakout boards, in 2 ports and 4 ports variants.
