Steve ][ natively supports the WOZ 1 disk image format, and DSK / DO / PO formats. For example, the DOS 3.3 Master disk with Integer BASIC can be fully loaded in less than a second. Furthermore, Quick Disk Mode speeds up disk operations drastically. In Normal Mode, one can hear an authentic disk sound which can be turned on or off.

And because of that, we can use Steve ][ on an airplane for a longer period of time while enjoying quick burst operations, such as compiling Assembly source code with Merlin.ĭisk operation also provides some notable features. However, when the user starts typing, it automatically unpauses and lets it run at the speed determined by the Speed Selector. That means that games react faster for keyboard and joystick / mouse inputs.Īnother CPU mode is ECO Mode, which is similar to Normal Mode, except when the Apple II is only waiting for keyboard input, it sleeps the machine, therefore it only has minimal energy impact on the host computer. We can switch to Game Mode, which doubles the screen refresh rate and lowers input latency to 1.5ms. In Normal Mode, the screen is refreshed at 30 FPS and input latency is about 33ms, which is prefect in normal situations. Steve ][ also includes some interesting features, like CPU modes. A bit lower or higher speed than this is possible, depending on the host computer and which apps are running at the same time. When it is moved all the way to the right, the roaring 1.3 GHz is achieved. The CPU speed selector is conveniently accessible from the middle of the toolbar as a slider. There is also a CRT mode, which is a graphics rendering technique to get the real feel of old CRT monitors, complete with scan lines and a tiny little bit of blurry effect. In Mono mode, one can select between Green, Amber and White phosphor monitors. It fully supports GR and HGR graphics video modes in Color and Mono monitor modes. It includes a 64K memory expansion card emulation which is also works as a 16K Language Card and an 80-column video card.

Tamas continued, “Steve ][ is capable of emulating an Apple II, Apple II Plus and Apple IIe, depending on which ROM is selected from the Config menu. What I found especially interesting was Tamas himself and the story of what inspired him to write Steve ][ was built today’s technology….”
