Last year I built one of the Performer clones from Bolle's github PCB/GALs. I believe this is identical to the version sold by Mac Effects. I did a build write-up over at 68kMLA. I did not take detailed notes on what version of Speedometer and system software I was running, though Speedometer...

Are you sure it doesn't still work? I accidentally snapped the plastic housing on one and it still works fine.

You would really need to be looking for that spot to even notice it. I'm curious what happens in the coming months. At least with Retro Brite, some people have said the yellow returns quickly even without exposure to light, and others have said it takes a long time.

Wow, impressive results. I'm especially impressed there is no outline of the badge in the lower-right corner. How did you ensure the sides got even sun? Did you rotate throughout the day?

Well I was reading your message before I had coffee, so our mental states probably weren't far off. Thanks for the advice, I'll update after I get some time to test further.

Thanks for the info. Alternatively to powering through the USB plug, the board also has a pin header I could use to provide power. This might be easier than stripping a mini-USB cable and connecting those wires to a Molex connector. I think I may have a spare Molex cable in storage I could cut...

I was originally going to hack up a mini USB cable to power the MacSD through the mini USB plug, pulling power from the Molex connector for the original hard drive. However, I figured since I had the same symptoms whether I was running the MacSD off SCSI term power bodged from the DB25...

I am having a strange audio issue when I use my MacSD internally in my IIsi. I modified the IIsi to have term power to the internal SCSI connector by bodging from the DB25 external SCSI connector, and I also tried powering the MacSD with an external USB wall adapter. The machine works fine...

Haha I think it's more that my mom hated my hobby and saw her opportunity. 😂 I remember I had a couple door games, but couldn't say which ones.

Unfortunately no, when I went off to college all my old computer stuff magically disappeared. 🫤

I ran a 2-line BBS with Hermes when I was a kid, on a '040 accelerated Mac II. The guy who wrote the Hermes software lived a couple streets from me, so I just walked up and bought my copy directly from him.

The diodes and bodges look good.

I forgot to put this in my last post. In your third photo, some of those traces are definitely gone and need to be replaced, but some are probably still good under the corrosion and lifted solder mask. You can carefully use an x-acto knife to scrape the solder mask off. If you can scrape off the...

I'm glad to hear you are making progress. Do you have more photos of the damaged area of the board? In your third pic there are definitely a couple rotted vias. Have you checked what they connect to, and come up with a plan to repair those? If the via just goes straight through the board and...

Did you find one to purchase, or are you going to build your own? Last I heard there is not a known source for the clip that clips over the 68000 on the Classic, it is a newer package type than the 68000 used in the Plus.
