Emu8086 is described as You can run the emulator either on the Linux machine where you installed ZD&T Personal Edition, or on your personal Windows, Mac devices to access the ZD&T z/OS.Alexander Patalenski | Emil Dotchevski IntroductionDownload 8086 Simulator Mac Software.Run DOSBOX, and on its command prompt enter the following commands (replacing with the location where you unzipped Appler):Feel free to create GitHub issues, hopefully I can help.Appler's startup disk boots the classic Apple ][ software is available for download at:Before talking about Appler, I should introduce the machine it emulates, the amazing Apple ][. Double-click the downloaded file to unzip it.Next, download and install DOSBOX from. :) Running ApplerTo download Appler, click the green Code button in GitHub, and in the drop-down menu select Download ZIP. Download and Install.This distribution contains the executable binaries as well as the complete source code.At the time of this writing, Apple ][ games running on Appler running on DOSBOX running on MacOS. It is recommended for all users of Visual Basic 6. 22 (August 2001) - DOS: ts1000-c. Complete tasks on outlook for macThe entire bottom of the case, on which everything else is bolted on, is a solid 2mm steel plate which doubles as a giant heat sink for 100% silent operation:I don't know how much one of these cost, because in Communist Bulgaria such things were considered "means of production" and nobody could own one. You either write the code every time you turn the power on, or else read it from a cassette tape.Next was the Apple ][, which had a yellowish skin:Curiously, it supported the Cyrillic alphabet right out of the box.I'm kidding of course, the above is the Bulgarian-made clone of the Apple ][.It is perhaps unfair to introduce the illegal clone before the original American masterpiece, but let me assure you, behind the commie skin the brilliance of Wozniak's design was intact, and it was built like a tank. Back in those days, when you booted up the computer, there was no software loaded on it. This is a nice surviving example, mounted in a briefcase:Notice the compact cassette player. He designed and put together the Apple I, which was sold as a kit, meaning the computer was sold barebones, and had to be assembled by the buyer. ![]() This improved Electric Duet sounded like this).This minimalist approach seems counter-intuitive, but only if difficult to write software is seen as a downside yet software - unlike hardware - is free to distribute. And yet, Paul Lutus gave us The Electric Duet, which plays two voice music (though it produced an audible 14,080 Hz noise as a side effect of duty cycle modulation Alex wrote his own player from scratch to fix this, and hacked into the binary code to replace the original player. In contrast, the Wozniak design does about 10% of what most reasonable people would consider sufficient for it to be called Disk ][ Interface Card, and yet there it was, and it worked beautifully.As another example, consider the Apple ][, each access of address $C030 inverts the polarity of the speaker, and that's all of the support you get from the hardware. The IBM controller has its own CPU, supports DMA, and does a lot of heavy lifting that makes it easy to write the software. The bl register is kept at zero.With this arrangement, here is the complete implementation of the 6502 instruction INX (increment the X register):Because incrementing cl leaves the ZF and SF in the correct state that matches the semantics of INX, there is no more work to do, we simply load and execute the next opcode.All of these acrobatics are no longer needed, but back when we wrote this code Appler achieved 75% of the speed of a physical Apple ][ (which runs at 1 MHz) on a 4.75 MHz PC/XT.Depending on the selected video mode, writes to some 6502 memory addresses need to be visualized to emulate the Apple ][ video controller. The stack pointer is stored in memory.The reason the PC register is stored in si is that this makes it possible to load the next opcode or 8-bit operand using lodsb, and of course 16-bit operands can be loaded via lodsw.All of the CPU emulation code occupies 64KB of contiguous memory, with the emulation routine for each opcode located at the beginning of each 256-byte segment. Wozniak himself set an example of what's possible, managing to fit in 12 KB of memory a Basic interpreter, a program editor, and a debugger.The Hollywood blockbuster The Terminator featured some 6502 code for Apple ][ in several scenes, seen on the Terminator's HUD:Most of the state of the emulated 6502 CPU is stored in 8086 registers:The Z and N flags are stored directly in the 8086 ZF and SF, while dh stores the C and the O flags. In that mode, there are 280x192 pixels. Mixed graphics/text is supported as well.The Apple ][ high resolution graphics mode is commonly referred to as HGR, named after the corresponding BASIC command. High graphics mode (280x192) is emulated at double horizontal resolution. These routines share the same instruction space used to implement the 6502 opcodes, occupying the second half of each 256-byte segment (so, the emulation routine for opcode $20 ( JSR) shares the same segment as the emulation routines for reading and writing at addresses $2000.$20FF.Both 40x24 text mode and low graphics mode are mapped to the PC 40x25 text mode. Pixels at odd-numbered screen columns are either green or orange Pixels at even-numbered screen columns are either purple or blue Depending on the color palette bit: If a pixel-controlling bit is set, the corresponding pixel is on. If a pixel-controlling bit is clear, the corresponding pixel is off. There are only 4 primary colors which are carefully selected so they combine together to produce the 6 perceived HGR colors and there's no complex logic in hardware, if you light up two neighboring pixels, the colors "automatically" combine to produce white.At the time we wrote Appler we of course knew that the colors are supposed to be purple, blue, green, and orange, but we had never seen them displayed by an actual physical computer, because the Apple ][ displays that were available in Bulgaria were all monochrome-green. Here are the same 6 colors, but in smaller bands and turned at 90 degrees:And now, the same image zoomed-in, so we can see the individual - you guessed it - not pixels, but sub-pixels:Keep in mind, each vertical color line you see in this last image is half a pixel wide, two neighboring vertical lines making up a single vertical line of Apple ][ pixels. Indeed, Appler emulates HGR mode at the sub-pixel level, using double the resolution horizontally. Here are the 6 non-black HGR colors, surrounded by the two whites, as rendered by Appler:But how could a simple video controller from the 1970s implement such complex logic in hardware? How would neighboring pixels know about each other so they can turn white if they're both on? In fact they don't, and it's really simple (after all, it is Wozniak design), but you need to consider half-pixels.
