I realized tonight that there’s a specific Lisa mode for the FloppyEmu. Once I changed the mode it worked great!

Yep, I'm already on 0.8G F15

I've been restoring a Lisa 2 / Mac XL and am having trouble getting it to boot any images on a FloppyEmu. All images except the Mac Works boot image result in error 42. Per the service manual, this indicates "Disk controller timeout". I probed the entire disk controller circuit on the IO...

I figured it out on my board. A trace (poorly highlighted below) from a via just below D9 that ran below the battery was broken on the top side. I bodged it on the back side and standby/soft power started working normally. Now I get a memory error 70 during the startup test. Psyched to have made...

@Juror22Did you ever get your Lisa working? I'm having the same problem. The Lisa powers on when plugged in. I get I/O Error 52 (COPS error). I checked all the traces for the first connections from each pin of COPS and cleaned the chip and socket with contact cleaner, but the issue persists. I'm...

Sure enough, I found a bad connection one of the capacitors I replaced on the memory board. Now I have clean video and a Low - High - Low beeps which indicates an issue with the I/O board. So close!!

@stepletonIt's a single low beep. Per the service manual it looks like it's a problem with memory or CPU. The memory board recap was a little rough, so I'll check the traces on that first.

Turns out I didn't plug in the cable for vertical deflection, doh! Now I get a beep and some corruption on the screen. I'm guessing this is a bad trace or memory, but if you have advice for where to focus, please let me know.

I've been restoring a rusted out Lisa 2 / Mac XL and just got first signs of life. It's showing a horizontal dashed line. If I remove the memory board, the line becomes less defined. Increasing the brightness makes the line way too bright which makes me think I have a deflection issue. The PSU...

The original post doesn't cover C7 which is a .33uF 250v film cap. I'll add it with dimensions an lead spacing to an updated graphic soon. In the mean time, here's a photo of my recapped PSU. With a Hakko pump it was pretty painless to do.

Upon further research it seems these are .1uF (not .01uf) glass capacitors. It's hard to tell if this package type provides and major benefit over a more typical epoxy packages, but I found some stock of these on eBay so will replace like for like.

I'm restoring a Mac XL / Lisa that had a lot of corrosion damage on the frame parts. I removed the rust with Muriatic acid. It worked great, but that stuff is super nasty. I was taking them to a plating shop who does bead-blasting and chemical rust removal anyway, so it was super not worth it...

I just use a standard ATX extension cable. Cheap and ready to use from Amazon. It's wider than the connector on the compact Macs, but still mates with it and is pin compatible. https://www.amazon.com/gp/product/B07VN3DRFW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Can someone help confirm the value and type of caps at these locations on the motherboard? The label is tiny but looks like it's 104 25v.  I'm assuming that means 10,000pF (0.01uF) and that this is a non-polar ceramic cap. Is that correct?

I don't see any witness marks like that. It's a mystery for now :)  

So this is possibly an earlier Apple-owned production device that had a cable revision being tested?

@maceffectsThe model is A6S0300 with memory option A6S0304. Do you know what the "Applenet" number refers to?

As I was stripping down the Mac XL I'm restoring I noticed this wiring harness says 'Prototype'. Curious to know if any production units shipped with a label like this or if it's indicative of the whole unit being a prototype. The rest of the unit seems normal, but I'm new to Lisas so might be...

I'm in the middle of restoring a Mac XL. I didn't see a capacitor map online for these. So here is one  in case its helpful to others. Pardon the cob web filled PSU. I'll be cleaning that :) In addition to these there are some axial electrolytic caps on the CPU / IO boards too. Those are...

Yeah I’m not really looking to spend a lot of time on this, but figured I’d make them available for people who really want them. FWIW I priced them at $10/set on eBay with much smaller volume discounts. So there’s a substantial discount for people who buy here.
