SX-Window

SX-Window is a graphic user interface (GUI) operating system for the Sharp X68000 series of computers, which were popular in Japan. It was first released in 1989 and had its last update in 1993.[1]. It runs on top of the Human68k disk operating system, similarly to how Windows 3.1 runs on top of MS-DOS.[2]

History

SX-Window was introduced for X68000 in 1989, and came preinstalled on the X68000 EXPERT model. It was developed by Hudson. The final release was 3.1 in 1993. In 2000, Sharp released the system software for the X68000 into the public domain, including SX-Window.[3]

Technical details

The look and feel of the GUI is like that of the NeXTSTEP operating system, and its API is similar to the Macintosh Toolbox. It uses non-preemptive multitasking with the event-driven paradigm. It has a garbage collection system without MMU of MPU, but it was difficult to program because all pointers derived from handles become invalid once any API is called. The X68000 was very powerful for game software, but this GUI could be slow, as no hardware acceleration card was supported. Only a few applications and games were developed for this system.

gollark: It's called 5G because it's fifth generation because it comes after 4G.
gollark: No.
gollark: I don't like it. We use a BT router with that "feature" at home and I cannot figure out how to turn it off and it *annoys me slightly*.
gollark: Self-driving cars should probably not be using the mobile/cell network just for communicating with nearby cars, since it adds extra latency and complexity over some direct P2P thing, and they can't really do things which rely on constant high-bandwidth networking to the internet generally, since they need to be able to not crash if they go into a tunnel or network dead zone or something.
gollark: My problem isn't *that* (5G apparently has improvements for more normal frequencies anyway), but that higher bandwidth and lower latency just... isn't that useful and worth the large amount of money for most phone users.
