I didn't know about the RTC issue, but the separation of users from developers was strictly because of hardware limitations. The Lisa cost $10k and came from a separate division of Apple from the Mac, which sold for [around] $2500 and only had 128k of RAM and no hard drive. They were completely different target markets. Nobody at Apple at that time knew how to make a Pascal compiler run in the limited environment of the Mac. (But as mentioned above, the Forth vendors had no problem doing it.)
- Someone 9y agoDoes anybody know how to make a Pascal compiler run on such a system? The executable for Turbo Pascal for x86 was 39kB and likely needed more to run on a character-based screen. After subtracting video memory and sound buffers (combined about 22kB) and what the OS used, that 128kB Mac had, IIRC, about 28kB available for applications to use.
- pjmlp 9y agoI think the biggest issue was probably the IDE support and the Object Pascal features, given the existence of Pascal compilers on 8 bit OSes. I owned a few ones for ZX Spectrum, but they were basically standard Pascal + Z80 low level extensions. And plain single pass compiler with zero optimizations.
