leadedsolderNew blog post! If you're setting up a BlueSCSI image for your classic Mac, there's lots of little tricks and traps for the first-timer. I'm hoping this entry will make things easier, and you'll also learn how to change your hard drive icon... in Japanese. <a class="hashtag" href="https://snack.social/tag/retrocomputing" rel="nofollow noopener noreferrer" target="_blank">#retrocomputing</a> <a class="hashtag" href="https://snack.social/tag/mac68k" rel="nofollow noopener noreferrer" target="_blank">#mac68k</a> <a class="hashtag" href="https://snack.social/tag/bluescsi" rel="nofollow noopener noreferrer" target="_blank">#bluescsi</a><br><br><a href="https://www.leadedsolder.com/2024/05/21/bluescsi-preparing-a-disk-image.html" rel="nofollow noopener noreferrer" target="_blank">https://www.leadedsolder.com/2024/05/21/bluescsi-preparing-a-disk-image.html</a>
Rafael<p>Logic board and PSU recapped, 68LC040 replaced with the real deal, 16 meg memory upgrade, a nice new <span class="h-card"><a href="https://hachyderm.io/@BlueSCSI" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>BlueSCSI</span></a></span>, and a new (hopefully) quieter fan.

Rafael<p>Welcome home! Let's get you a nice cozy heatsink and get you settled back in your case.

Rafael<p>I had to take the logic board out of my LC 475 to get it recapped. I was super careful but the plastic is so brittle I ended up breaking a couple of clips. Most importantly the one that holds the system fan. Everything is stationary but that fan is going to move around if it's loose. I was thinking about hot glueing it to the case but I'm open to other options.

Rafael<p>Thanks for all the great info! I ordered a Blue SCSI and a new case fan, since the old one is pretty loud. I've got a couple of other questions:</p><p>Do you think it's worth it to spend $50-$70 to upgrade the 68LC040 to a regular 040 with an FPU? (Especially since I only spent $150 for the system.)</p><p>Do you know anyone who recaps old Macs? I'd like to get it done but my soldering skills are not "detail oriented". </p><p>Thanks! <a href="https://mastodon.sdf.org/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retrocomputing</span></a> <a href="https://mastodon.sdf.org/tags/mac68k" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mac68k</span></a> <a href="https://mastodon.sdf.org/tags/MARCHintosh" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MARCHintosh</span></a></p>
Rafael<p>It's alive! My Mac LC 475 is up and running! I'd like to take out the mechanical hard drive and replace it with something more modern and reliable. Is there a scsi solution that you like? <a href="https://mastodon.sdf.org/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>retrocomputing</span></a> <a href="https://mastodon.sdf.org/tags/MARCHintosh" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>MARCHintosh</span></a> <a href="https://mastodon.sdf.org/tags/mac68k" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>mac68k</span></a></p>
Brian Swetland<p>There we go, the Macintosh LC III is all set up and in a nice location to actually sit down and write some code. Got the display running at 832x624, which is spacious compared to 640x480 and doesn't look terrible on a used 19" Dell Display.</p><p>Trying out a QuokkADB to use a more modern, smaller, louder keyboard with it.

Brian Swetland<p>Oh here's a question for Classic Mac dev folks -- is there a library of sample code (C for preference) for interacting with common toolbox routines out there somewhere?</p><p>Searching for stuff that dates to the mid-80s or maybe early 90s is an adventure...</p><p><a href="https://chaos.social/tags/RetroComputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RetroComputing</span></a> <a href="https://chaos.social/tags/Mac68K" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Mac68K</span></a></p>
Brian Swetland<p>The classic MacOS code segment approach is kind of fascinating. I had just sort of assumed that, being a 32bit architecture, things would be much simpler, but I'm used to 32bit platforms that lean heavily on an MMU.</p><p>The desire for position independent code (and avoiding complex relocation) combined with the 68K's limit of 16bit offsets for PC-relative access, and the need to be very frugal with memory in early Mac systems clearly drove a lot of this design.</p><p><a href="https://chaos.social/tags/RetroComputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RetroComputing</span></a> <a href="https://chaos.social/tags/Mac68K" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Mac68K</span></a></p>
Brian Swetland<p>That was an adventure. Managed to get one of the included demos to build with Consulair Mac C 5.02 on System 6 (in the Mini vMac emulator).</p><p>Setting up working search paths with the Path Manager was a bit involved. The files on the install disks were not actually organized in a way compatible with the default search path setup.</p><p>And the resource compiler refused to write a .rsrc file, but would write a .rel, which did link with some changes to the link script.</p><p><a href="https://chaos.social/tags/RetroComputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RetroComputing</span></a> <a href="https://chaos.social/tags/Mac68K" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Mac68K</span></a></p>
