I recently picked up this 3400c that for the most part is in excellent condition other than needing a new power adapter, a replacement PRAM battery and maybe some service to the power supply board. (Or a replacement one).
After reading through Jeff Geerling’s restoration post and some posts on 68kmla I decided on an IDE to compact flash adapter and a SanDisk 4GB card.
Both worked immediately and were recognized by HD Setup. I split the card into two partitions - one for System 7.6.1 and the other for more data.
This 3400c came with a 32MB RAM upgrade. I’m going to pickup a larger RAM card in the future.

What isn't shown here is that the power supply board has been finicky - the PRAM battery was leaking and I cleaned that up. I didn't see any bad traces, but corrosion had moved through the battery wiring harness. I soaked that board in alcohol for a day and cleaned it. The caps aren't leaking - but I'm going to recap that board as a next step. I replaced the PRAM battery and relocated it to another part of the enclosure.
It's starting to come together. Great companion to my PowerBook 165c which was my first PowerBook restoration.
