Looking for old dev tools: Desk Accessories
Posted by: Frobozz on 2025-06-07 17:48:07
I recently found a book called under the apple, which is an early Mac book about all the wonderfulness that can be achieved by using desk accessories. This is pre-switcher/multifinder era. It has a chapter on developer tools, and some of these look like they would be pretty helpful. I can't find anything about them except a few references to them in magazine articles. Nothing on Macintosh repository, info-mac. MacintoshGarden.org hasn't been working for me the last couple weeks (they ok??), so haven't been able to check there.

Anybody have suggestions or even a download link?
- MemScan. looks like a basic ML monitor.
- Explorer, by Jim Goodnow II. Another ML monitor type DA.
- DisAssembler, by Ronald Nicholson, Jr.
- ConCode. Appears to be a 68000 instruction set simulator.
- HeapShow. This looks really interesting. It was commercial unfortunately, and that may mean there are no extant copies.

Wow... that HeapShow brought back vivid memories, complete with smell! I used it back around 1990, and it behaved just like in the documentation -- unfortunately, all I had was a school copy, and that's long-gone today. It was great for being able to visually keep track of memory fragmentation, and I used it to compact the system heap, which sometimes resulted in some instability, especially if it stomped on a range currently in use. But for applications, it did a great job of illustrating what was actually going on in the heap, and helped me quickly find leaks and dereferenced pointers.

you make me sad! but hopeful: some day it may turn up, and sounds like it would be a great little additional tool for devs.

ConCode and Explorer appear to be in this collection https://macintoshgarden.org/apps/lots-of-desk-accessories

Possibly this is Memscan on an old mac collection cdrom https://discmaster.textfiles.com/browse/13264/Gigarom Macintosh Archives (Quantum Leap)(CDRM1080320)(1993).iso/FILES/DEV/I-Z

DisAssembler too
