Liberated a Quadra475 for 90€ in Germany

I liberated a Quadra475 for 90€ incl shipping in Germany yesterday. Got it on Ebay:
www.ebay.de

Apple Macintosh Performa 475 + Maus + Tastatur Vintage Computer, made in Ireland | eBay

Das Gerät ist ungetestet. Ich habe es an Strom angeschlossen, aber es gibt keine LED oder ähnliches. Einen passenden Bildschirm habe ich nicht um ihn auf Funktion zu testen. Geräusche hat das Gerät keine gemacht.

The seller says it looks clean from the inside, but doesn't do anything when turned on. I guess caps have leaked on the logic board and PSU, as is tradition. I'll deliver pics as soon as it's here.

Maybe a bit pricey, but why not.

Still one of my favourite Macs. Compact, powerful enough for most of the things you could do with System 7 on a 68K, and they can be overclocked easily.

Hope you can get it going again. Even if the PSU is a corroded mess as they often are, replacements can be built with a Meanwell power supply instead.

I may have a broken Q650 board somehwere, the CPU with FPU should fit the 475 socket.

Got the 475, it looks good:

I didn't see any problems with the caps on the logic board so far. But obviously they will get replaced anyway:

The battery was fine, it expired 21 years ago. It's a brsnd i never saw before, "Hawker Eternacell", likely an aftermarket replacement. There are 1.2V left in the cell ;-)

The CPU, sadly, is the LC variant, it has no floating point unit:

The HDD is 160MB, i have a RaSCSI and a bunch of replacement HDDs, should it turn out to be broken.
VRAM is 2x 512kb, which is not bad. It appears the RAM is 32MB, not bad either.

I didn't have the stomach to open the PSU yet.😉
