In this video he doesn't fix the machine, which someone donated to him in an atrocious state: he just strips it down to the frame. The I/O board looks like what you get if you leave a peach on the counter and then head off on a month-long vacation; the motherboard is also pretty much toast; and the battery goo seems to have wicked into the ribbon cables even. The chassis has been bent a bit; Adrian suspects it was dropped by German customs, who may also have been responsible for some pretty slapdash treatment of some of the fasteners. Fortunately the plastic panels are mostly okay. The CPU board fared the best, there's just one memory board (Adrian assumes that by now someone has made a tiny 2MB memory board replacement, lol), and the power supply is gone altogether.

Adrian is no fool and understands that any kind of restoration here is going to be a Project. He's not certain that it's compatible with the kind of release schedule that YouTube demands of a full-timer. He concludes the video by hoping that Lisa experts in the audience can help him get a more realistic idea of options for next steps.

Yeah, this initial video was just the teardown to assess its condition. I understand he'll try to get it running by using some of the re-engineered boards from the community later on. Should be a fun series to watch.

Having done this exact thing to around 10 Lisas, it's neat to watch someone else tackle it for the very first time.

I've already added his machine to the tracker. Interestingly enough, his machine conflicts with one we assume existed at one point.

Adrian and I have been talking about this project for about two weeks now, and I'm going to try and do everything I can to help him get it working again. The motherboard and I/O board are absolutely horrendous (the only ones that I've seen that were worse were the ones in my first Lisa that inspired me to make replicas) and I'm not sure that they can be saved without an absurd amount of effort. Adrian happens to be visiting my city soon, so I'm planning on giving him some bare boards and a working power supply when he stops by. Hopefully we can get it up and running again!

Wish I'd known this up front! I went in expecting a miracle and felt sad at the end that he was basically giving up.

Glad there's a future for this thing and looking forward to seeing what comes next.

Well, regarding the 2MB question, I do have a working solution.

Oh nice, it's awesome to see a clone of the RAMStak! I've been wanting to clone it for a while, but it looks like you beat me to it. Are you planning on publicly releasing the files anywhere?

Hah, I wasn't paying attention and thought it said Lisa2! Do we have a new admin?
