Notes

In this video, I spend a little time adding a feature, then a lot of time finding a crash.

In this video, I create a new GUI application from scratch, create a resource file and add an image to it, and then display that image in a window. I also cover using THINK C’s debugger to inspect a struct. Then, my Mac dies.

Inspired by @awesomekling@twitter.com, I am going to try recording some videos of my C application development on my old Mac. Here's a quick introduction to System 6, THINK C, and my IMAP client.

Making a thing...

A few new capacitors and the old boy lives to see another day of programming

After programming on my Mac 512k every day for the past month or so, its analog board seems to have died :(

I've been learning the Macintosh Toolbox APIs for System 6 and couldn't figure out why some functions had short names like "DisposDialog" but others "ReallocHandle". Turns out Apple's Pascal compiler made routine names significant to only 8 chars, making long names collide.

PPP over @paulrickards@twitter.com' WiFi232

I bought a Mac 512k for parts and upon opening it, I discovered it has a Mac Rescue board installed which adds Mac Plus ROMs, SCSI, 4mb of RAM, and an 800k floppy drive. Glad I just upgraded my 512ke to 1mb 😕

I'm writing a program on my Mac and the VB3 programmer in me had to start with the About box

I miss you Carl

It's a 2005 kind of day

This was inevitable

And Eudora 1.3 runs, so I can get POP3 email and send via SMTP.

I wonder how much work I could get done on just a Mac with a megabyte of memory.

With 1024kb of RAM, I can finally run MacTCP, MacPPP, and a client application to natively use the internet with the Mac's own IP stack (NATed through my OpenBSD firewall via pppd).

That just seems so much cooler than offloading all the IP to a Wifi232 pretending to be a modem.

If your OpenBSD machine needs a bunch of serial ports for... some reason... the Exar XR17V35x chip in the IO Crest SI-MPE15047 4-port Mini PCIe card is properly supported now

I added another 512Kb of RAM to my Mac

When you haven't had electricity for three days, it's good to have a 50-year-old radio that runs on batteries
