The current version runs on PowerPC Macintoshes under MacOS X 10.3 and later, and on Intel Macs under MacOS X 10.4 and later. Catakig is an emulator for the popular Apple II series of personal computers, supporting the Apple , +, //e, and //c models. However, if you are a Mac OSX user, your option list is shorter, and if you start looking around, most of the options available haven’t been updated for ages, or they don’t offer a good. The Apple II family of computers has its fair share of emulators available, as shown in sites like Zophar’s Domain with its Apple II emulator list.Emulates Apple //e enhanced computer.At 320 x 200 pixel resolution, the IIGS supported 16 colors from a palette of 4,096, not unlike EGA. The Korean Apple II Community has been busy this month Keonwoo Kim has released AIPC, an Apple IIe emulator for Windows with an impressive list of features AIPC is freely available open source software released under the GPL. Other Apple IIgs emulators and other KEGS.AIPC (Apple in PC) Apple IIe emulator released. The GS stands for graphics and sound, two areas where the IIGS stood head and shoulders ahead of the rest of the Apple II line – not to mention the black-and-white Macs of the day or the 16-color EGA that was becoming standard in the PC world.KEGS emulates an Apple IIgs accurately at between 400MHz and 750MHz on pretty much any Unix/Linux system or Mac OS X. The next generation of emulators, the Octalyzer hopes to. The Apple IIGS changed all of that.The Octalyzer is a multi-tasking Apple IIe emulator, with enhanced (but compatible) language interpreters, expanded modern capabilities, and (eventually) an integrated on-line bulletin-board system and media library for exploring computing’s past with all the comforts of the present.
Apple Iie Emulator Mac OSX UserIt has 320 x 200 and 320 x 400 graphic modes supporting 32, 64, or 4,096 colors, as well as 640 x 200 and 640 x 480 16-color modes. Between the graphics and the sound, the IIGS was a great gaming platform.These features also put the IIGS in competition with the 1985 Amiga 1000, Commodore’s breakthrough computer for graphic and audio work. The IIGS was the first personal computer to use a fully digital synthesizer chip, the 8-bit Ensoniq 5503, which has its own memory and supports 32 channels and 15 separate stereo voices (the 16th is reserved for the operating system). An Apple IIgs emulator for Mac OS X and Linux, to 1.07. A higher resolution 640 x 200 pixel mode was limited to 4 colors per line, 800 colors total.cyanIIde is a free webassembly-based emulator that you can use to embed an Apple IIe emulator into. Designer program for macThis port was used primarily for keyboard and mouse, but could also be used by a graphics tablet or a modem. Nintendo’s Super NES uses a variant of the 65C816 running at 3.58 MHz, the Acorn Communicator held it down to 2.0 MHz, while the SuperCPU upgrade for the Commodore 64 runs at a blazing 20 MHz.)The IIGS shipped with 256 MB of system memory and can be expanded as far a 8 GB – twice as much as the Mac Plus.Apple introduced the Apple Desktop Bus (ADB) with the IIGS. (For the record, the 68C816 was never popular. The Mac Plus was Apple’s flagship computer with 1 MB of memory and an 0 CPU, and Apple didn’t want people to perceive the IIGS as competing with Macintosh.The 68C816S design runs at up to 14 MHz, and by holding the CPU to 2.8 MHz, it was at least 80% less powerful than the Mac – and thus no competition at all.That said, compared with a , the 2.8 MHz 65C816 was a real screamer. Instead of using the old 6502, it used the new 65c816 from Western Design Center, which is nearly 100% backward compatible with 6502 software – it can boot directly into older versions of Apple DOS, as well as use ProDOS, the new Apple operating system based on Apple III SOS.Instead of plodding along at 1 MHz, the new CPU runs at 2.8 MHz, and this was probably the most debated decision Apple made about the IIGS. The US$1,295 Amiga edged out the US$999 IIGS in graphics, but the IIGS beat it on the audio front.The Apple IIGS was the only model in the Apple II line to use a 16-bit processor. Because the “signed” (really silk screened) cover could be moved to another IIGS, Woz editions are no more valuable than the regular IIGS.Believe it or not, there was even an Apple IIGS upgrade for the Apple IIe for US$500 – half the cost of the new computer. Macs would adopt Platinum and ADB starting in March 1987.Perhaps the most disappointing part of the IIGS design is that it did not include a built-in 3.5″ floppy drive.There was a limited edition of 50,000 Woz signature Apple IIGS computers produced for Apple’s 10th anniversary. Apple later released the Apple IIe Workstation Card, bringing netbook capabilities to the Apple IIe.)The IIGS continues the Snow White design language introduced with the Apple IIc, and it was the first Apple product available in Platinum, Apple’s name for a warm shade of grey. (This was over a decade before Macs would get the same capabilities with the release of Mac OS 8. Since it already had a floppy drive port, two serial ports, and ADB port, plus composite and RGB video ports, there was far less reason for users to add cards, although adding Apple’s High Speed SCSI Card and a SCSI hard drive was a good one.The IIGS was the first Apple II machine with a real time clock, and it could connect to a LocalTalk network and boot from an AppleShare server. ![]() You will need to acquire a ROM image from a IIGS, and the emulator is available for Mac OS X, Win32, and most Unix/Linux computers. If you’ve got a IIGS, be sure to check out the free download.If the IIGS intrigues you and you’d like to give it a virtual try, the KEGS Apple IIGS emulator is available. GS/OS would continue to be updated annually until version 6.0.1 was released in 1993.Would you believe that GS/OS 6.0.2 was released on July 15, 2015? It’s not from Apple, but it squashes a number of bugs that remained in version 6.0.1. RAM Disks were limited to 4 MB with the original firmware, even if more RAM was installed. By late 1987, new software written for the IIGS would be incompatible with the original ROMs, and GS/OS 4 and higher were not compatible with them either. Original ReleaseThe first ROMs used fairly buggy code, which some call “almost beta quality”. Some customers actually wanted their old ROMs reinstalled until the software was fixed. Beyond 2.8 GHzThe 65C816 began as a 4 MHz chip but was available in 5 MHz and 14 MHz versions, so you know someone had to find a way to make the IIGS run faster than 2.8 MHz. This ROM version was not available as an update, since it was specifically tied to the new motherboard. ROM Version 3ROM Version 3 came out two years later, in August 1989, when Apple updated the IIGS system board and shipped the IIGS with 1.125 MB of RAM. 512 MB Apple IIGSIn March 1988, Apple began to ship the IIGS with an Apple IIGS Memory Expansion Card preinstalled, bringing RAM up to 512 MB – 256 MB on the system board and 256 MB on the card. Software developers immediately stopped coding for the original buggy ROMs. This included several bug fixes and updated system tools. The ZipChipGS shipped with 8 KB of cache memory, while the other two included 16 KB. ZipGS Accelerators from ZIP TechnologyZIP Technology offered three 8 MHz accelerators for the Apple IIGS: ZipChipGS (Model 1500), ZipChipGS Plus (Model 1525), and ZipGSX (Model 1600). Applied Engineering also offered a 32 KB cache upgrade to further boost performance by an average of 22%. Some have modified the TransWarpGS to run as high as 18.75 MHz. It has a control panel built into the card that lets you choose between 1 MHz, 2.8 MHz, and 7.0 MHz. TransWarpGS from Applied EngineeringTransWarpGS lets you more than double performance of the Apple IIGS using a faster CPU and an 8 KB of cache memory.
