Interesting, years ago when I did a lot of hardware, one would track down problems with voltmeters, continuity testers, oscilloscopes and logic analysers. Now people seriously sugg…

Thanks tl and JDW. I did recently acquire a IIsi ROM off Ebay (first one I have seen in years of looking) and unfortunately it was a dud: http://68kmla.org/forums/viewtopic.php?f=…

*looks through Legacy CD*

Some thoughts on your mini, though. If the fan runs often, I would be concerned about the operating environment, especially if the SE is trapping most of that hot air inside the ca…

You probably don't have one to test, but since that card is officially compatible with a IIsi, I would be curious to see if the accelerator worked in the SE/30 with a IIsi ROM inst…

It might be worth tracking down a IIsi ROM SIMM...

Hello, A year or so ago I purchased a grab bag of parts on Ebay that included a MicroMac Carrera040 http://micromac.com/products/carrera040.html. The card is the 33mhz model desi…

or just use the LC III System 7.1 disk tools disk (which is on the Legacy CD) if it doesn't work, I'll PM/email you a SuperBooter image.

Apple doesn't replace motherboards because of leaking capacitors anymore. The machine in question is now 4.5 years old and did not have Applecare. According to http://www.apple.com…

the 7.5 nad worked fine before. the problem is NONE of my bootdisks are working: an old 7.5nad (system error) the new one (bus error) the 7.6 disk tools disk (happy mac, then back …

My current recommendation is to contact Apple and elevate the issue to a supervisor. The supervisor will almost certainly give you a free repair. Capacitor replacement is no longer…

Just try a different boot disk (i.e SuperBooter 7.5)

You fixed a bus error by washing the mobo? how would I go about washing the mobo?

As I've said in another thread here recently, I used to get this a lot with an LC 575...washing the motherboard took care of the problem. It could be cap related, or any number of …

I just wrote a System 7.5 NAD floppy to complete the OS 8 on LC III hack, anjd was gretted with "Sorry, a system error occurred. bus error to temoporarly turn off" blah blah blah..…

Any good old fashioned TV repair person could do it - you don't necessarily need someone who knows computers, you just need someone handy with a soldering iron and a good collectio…

This is my favorite PPC machine, hands down. I affectionately call mine weirdway. I even used it as a sever for a bit. NetBSD & Linux run like a charm [as does OS9 &amp…

heat is actually the main issue with that setup, with the SE case being nearly hermetic, and the Mini's fan having to do all the job. Click to expand... I took another look at …

Some more thoughts about the airflow in a SE's case: I built my Macminitosh putting a Mac Mini inside a SE case. And heat is actually the main issue with that setup, with the SE ca…
