Alex Perez has reached out to me seeking permission to sell the design on his store, Rabbit Hole Computing. I have authorized him to sell the mAcTX LC and use the mAcTX LC name for the product. You are, of course, still free to download the design and make your own adaptations as you see fit; I...

I have been told that the original post got lost in a forum crash, so. Once again, here's the mAcTX LC KiCad project. Public domain, do whatever, yadda yadda; I just ask that you don't use the mAcTX name if you use this in your own project and don't sell for profit. This only covers the LC...

So let's see, between this, the MacEffects SE case, and Kai's SE logic board repro... are we able to make a complete, brand-new run of Mac SEs exactly as they would have been made factory in '87? :D

In addition to the above update, here's some news on the mAcTX LC front: I do intend to produce another run of boards at some point. However due to the uncertainty of USPS's future, I will not be offering any more for sale until this picture becomes a little more clear. Maybe I will have to...

Pictures are over here:  The last batch I did with a $10 flat shipping charge, $30 for a DIY kit or $40 fully assembled. Bring your own picoPSU.

More than likely, the board caps are the culprit here. Bad caps on the logic board make the system behave weirdly like what you're seeing. As far as the no sound issue, check the blue wire on the power supply - the LC needs -5v to generate sound and I'd be willing to bet that your power supply...

Now this is interesting - My Powerbook 150 has a surprisingly good battery for being a 25-year-old NiMh, but I've got several really cool PC laptops with dead NiMh batteries that I'd like to revive at some point.

This'll be a fun project and I might have to get in on a board or two. Both my SEs sit in the corner gathering dust because they have bum SIMM sockets. Stupid brittle plastic clips.

Grab a set of calipers ($20 at Harbor Freight - https://www.harborfreight.com/6-in-digital-caliper-63711.html ) and measure the diameter of the original capacitor, then try and find something similar to that.

I've got the initial disk images you posted over here and it's no trouble to get it reinstalled :)

I ended up paying about that much per 4164 off eBay to get my 128k going.

So it boots off an X/Profile on a 2/5. HELLO.APP works, but 1ST_WORD.APP causes a complete system hang when trying to create a new document. Make sure to have a floppy disk inserted if you try to access the drive, otherwise it will crash the system with Lisa Error 47. Also: don't forget to copy...

As a side note, does anyone know what happened to the Lisa Office System source release from a few years back?
