It was quite ease. This YouTube video explains how: How To Repair TAM's Bose Buzz - #MARCHintosh Launch Video Featuring The 20th Anniversary Mac! - YouTube I'll have look a the 65/6400 PSU and will share my findings here.

I am looking for a replacement of my defective PSU for the TAM. Ebay lists PSUs with similar part numbers but I am not sure if these are also suitable for the TAM. The OEM part number is dps-150gb-1 A, that Apple part number is 614-0057. What options are there to be used as a replacement from...

I've been trying to get the CFFA to work but my Apple /// does not see it. I double checked SOS.DRIVER to include the CFFA driver and that the slot number is correct. Jumpers 4 an 7 are set to "on" on the board. Any other ideas what the issue could be?

I've used the Apple /// in the 80thies and started to use it recently again but I never had to deal with a prompt like the Apple II does. Regarding FloppyEmu: Since the drives are differently addressed by that Apple /// than the Apple II, the FloppyEmu needs an adapter. I'm just in the process...

My PB180c shows a white bar on the upper lower half of the display. Before I start with recapping: Any ideas what could cause this? I received it like this, haven't opened it, yet.

I am super excited that my Apple /// has arrived. It was gifted to me by an old work colleague of my fathers. They used to work at an insurance where they brought them with their own money to bring a modern policy management and risk engineering solution to their desks without having to use the...

I'm soon going to get an Apple /// and am thinking of adding a CF-card adapter/card into it. I found the CFFA3000 to be compatible for it. However, the documentation for the Drive/Turbo does not mention the Apple ///. Does anyone know why doesn't work on the ///?

Yes, most of it. More in it's manual: https://mirrors.apple2.org.za/Apple%20II%20Documentation%20Project/Interface%20Cards/Apple%20III/Titan%20III%20Plus%20IIe/Manuals/

Was that best practice in the late eighties?

I noticed that both of my blueSCSIs don't recognize the "bluescsi.ini" file. The log file states: "Config file bluescsi.ini not found, using defaults" I "nuked" the blueSCSI and updated to the latest firmware. No change in behavior. Any thoughts on what the issue could be? Update: Typical...

Thanks all!

What could be the issue with this CRT? The Mac booted nicely just minutes before this appeared.

Did you eve find out what the issue was? I'm having a similar issue, though my screen is very, ver dim and the brightness buttons don't have any affect. The CC boots fine regardless.

So I fixed the broken trace I saw last week, re-soldered the UA5 and checked the capacitors C10, C11, and C12. Sure enough, the negative pad of capacitor C10 had a broken trace too. Now the Mac starts-up with a noise at least (see attached video). I'll check the area around the sound chips for...

Thanks for the hints. I desoldered UE5 and noticed a broken trace between pin 6 and 7. Pin 7 didn't appear to be connected to the pad either. I'll try to repair it over the weekend and see if that fixed the issue.

Here's a shot of the entire board.

Whenever the IIsi wants to play sound, it freezes, sometimes immediately or after two or three attempts (like changing the alert sound in the Sound Control Panel works 2-3 times, then the si freezes). The Mac was recapped before I received. It appears the pads are gone for C33 & C35, including...

I saw similar behaviour on my IIsi. In my case I had a PiSCSI attached to it. The drive spun up for a couple of seconds, the spun down. And not back up after reboot. I haven't tested it on another Mac, yet, though.

Here's the control panel. I suspect this is what activates the accelerator. Let me know if it works.
