So, after some confusion around disk image transfer shenanigans related to the way Microsoft changed UAC in Windows 7, the Apple III is in good, running condition once again. As I was digging through the cases, I noticed something I’d missed the first time around: holes. Specifically, a series of holes Apple drilled through the pressed aluminum case of the two later models I have:
These are not present in the earlier Apple III I have:
What’s interesting to me about this is that these holes exist in the case of one of the two 12V models, indicating that Apple knew about and was trying to address design flaws even before they officially started the replacement and upgrade program. Remember that before Apple released the III Plus, they first rolled out a revised Apple III which featured some significant changes to the machine’s design, including the aforementioned holes, as well as a new more efficient 5V power system. But the presence of the cooling holes in this 12V case (serial number 050756) shows that Apple were aware early on of the troubles plaguing the machine.
At any rate, after a handful of successful disk image transfers, I loaded up the Apple /// Dealer Diagnostic disk. I’m not sure if the obvious issues with the color video modes are the fault of the Apple III or the monitor it’s plugged in to. I’ll need to dig further into that:
