Andy Hertzfeld: We’re Not Hackers! We were always dealing with memory limitations. In: The Original Macintosh – Anecdotes about the development of Apple’s original Macintosh, and the people who made it. Folklore.org, September 1983, abgerufen am 9. November 2016 (englisch). “… as we started to get some software going on the prototype, it became increasingly clear that we didn’t have enough RAM for the kind of graphic intensive applications that we wanted to build; … Burrell added another row of 8 memory chips, doubling the RAM size to 128K … ROM is half the price per bit of RAM, so it makes sense to use as much as we can. … Fortunately, we had started to use the resource manager to load objects like fonts and drivers, so we had some flexibility about keeping stuff on disk instead of the ROM. … But code on floppy disk is much slower to load, and it also would reduce the effective size of each disk.”
David Craig: 3rd Party Developers and Macintosh Development. Some Comments about Developing Applications for the Apple Macintosh 128 Computer from a 20 Year Perspective. In: The Original Macintosh – Anecdotes about the development of Apple’s original Macintosh, and the people who made it. Folklore.org, Januar 1984, abgerufen am 9. November 2016 (englisch). “… Sophisticated Macintosh applications required more resources than the Macintosh 128 provided. The original Macintosh’s 128K bytes of memory and 400K byte disk drive were on the small size when it came to sophisticated applications (I recall reading that even in Apple there was lots of discussion about this). The original Macintosh was really around a 90K byte memory machine since the screen took 22K bytes of memory and a bit of memory was devoted to system code such a ROM patches and file system buffers. I recall my Investor application was around 200K bytes in size and though it ran on the original Macintosh it was slow due to constant application code segment swapping. …”
