The site that Crutch referred to has a large collection of bitmapped fonts. For pre-System 7 Macs, you can install the TrueType INIT and use TrueType fonts too.

Yes, I think that is a correct understanding. If you implement Apple's documented ENET driver interface, then your driver will be compatible with AppleTalk Phase 2 as well as MacTCP.

Fantastic!

Do refer to the AppleTalk chapter in Inside Macintosh volume VI for the standard driver interface, if you are not already aware of it.

I think that if you review the AppleTalk chapter in Inside Macintosh volume VI you'll find some discussion on the .ENET and .ENET0 drivers which would be applicable.

Are you sure the clicking is coming from the speaker? The power supply will click when there's no load on it. Here's a good starting point: Replacing the Flyback Transformer. Also be sure to turn on your sound and watch the two QuickTime movies which are listed in the Comments at the bottom of...

I do, and I documented my investigation and repair here: Fixing a Mac 512K with Intermittent Black Screen

Hard drives of the time (and still today of course) were engineered to be able to run continuously for months on end. But there are different factors at play now because this equipment is 25, 30+ years old. I'll leave my compact Macs on for long periods, unattended, but only if I'm still awake...

With ResEdit, look at STR resource ID 0.

There's a small detail missing here: the Segment Loader does not unilaterally unload (purge) segments. According to Inside Macintosh, it will only purge a segment by an application's directive: when an application calls UnloadSeg for a particular segment. UnloadSeg marks the segment as unlocked...

Error 41 usually means "can't load the Finder" typically because the Finder file is missing from the blessed System Folder. But you might see that error if the Finder is present, but can't be loaded into RAM for some other reason.

They say you're not supposed to use dish soap when you wash a board. But if you do a thorough rinse job, you're probably OK.....

I don't believe this is a correct description of how the Mac operating system works. Under a 68K-only system, the Segment Loader will typically only load CODE resource 0 (the jump table) and CODE resource 1 (the main segment) into the application heap when you launch an application. If the...

The original series LaserWriter uses a Canon marking engine.

Beta 5 is now out for testing. Features the first real TCP/IP application, a prototype POP3 email client. It logs in and downloads messages and saves them as text files on your disk. Email me if you'd like to beta test.

Here's the followup from some research I did, because I'm not an expert on all things, and I am still learning. The Sony Sound chip was new with the Macintosh Plus and Macintosh SE. The original Macintosh logic board has an Analog Sound Generator chip. From its pinouts found in this...

I don't believe that the original Mac 128K and 512K motherboard has a sound chip. Inside Macintosh volume III shows how sound is generated on these models.

Once you've enabled AppleTalk on both computers and connected them with a cable, they're networked! That was the big innovation of AppleTalk in 1984 and 1985: it was the world's first zero-conf networking system. You are right in saying that AppleTalk is standard on all Macintosh models back to...

I don't know. And when I say CPU, I also mean with its supporting components like the oscillator.
