ed this when using appleworks classic or the mousedesk application that was a part of system 1 and 2 apple resolved the issue by offering a free chip swap upgrade to affected owners second firmware release rom version 01 edit in august 1987 apple released an updated rom that was included in all new machines and was made available as a free upgrade to all existing owners the main feature of the new rom was the presence of the system 2 x toolsets and several bug fixes the upgrade was vital as software developers including apple ceased support of the original rom upon its release most native apple iigs software written from late 1987 onwards would not run unless rom 01 or higher was present and this included the gs os operating system this update also allows up to 8 mb for the ram disk added some new features for programmers and reported the rom version and copyright information on the startup splash screen standard ram increased to 512 kb edit in march 1988 apple began shipping iigs units with 512 kb of ram as standard this was done by preinstalling the apple iigs memory expansion card that was once sold separately in the memory expansion slot the card had 256 kb of ram on board with empty sockets for further expansion the built in memory on the motherboard remained at 256 kb and existing users were not offered this upgrade third firmware release rom version 3 1 mb of ram edit in august 1989 apple increased the standard amount of ram shipped in the iigs to 1 125 mb this time the additional memory was built in on the motherboard which required a layout change and allowed for other minor improvements as well this update introduced both a new motherboard and a new rom firmware update however neither was offered to existing owners even as an upgrade option the new rom now two chips is incompatible with the original single socket motherboard apple had cited the reason an upgrade was not being offered was that most of the features of the new machine could be obtained in existing machines by installing system 5 and a fully populated apple iigs memory expansion card the new rom firmware was expanded to 256 kb and contained the system 5 x toolsets the newer toolsets increased the performance of the machine by up to 10 due to the fact that less had to be loaded from disk tool rom read access being faster than ram and their highly optimized routines compared to the older toolsets pre gs os based in addition to several bug fixes also added were more programmer assistance commands and features a cleaned up control panel with improved mouse control and ram disk functionality more flexible appletalk support and slot mapping in terms of hardware the new motherboard is a cleaner design that drew less power and resolved audio noise issues that interfered with the ensoniq synthesizer in the original motherboard over four times more ram is built in with double the rom size and an enhanced apple desktop bus microcontroller provides native support for sticky keys mouse emulation and keyboard led support available on extended keyboards hardware shadowing of text page 2 was introduced improving compatibility and performance with the classic apple ii video mode the clock battery is now user serviceable being placed in a removable socket and a jumper location was added to lock out the text based control panel mainly useful in school environments support for the apple iie to iigs upgrade was removed and some cost cutting measures had some chips soldered in place rather than being socketed as the firmware only worked in this motherboard and no new firmware updates were ever issued users commonly referred to this version of the iigs as the rom 3 international versions edit like the apple iie and apple iic built in keyboards before it the detached iigs keyboard differs depending on what region of the world it was sold in with extra local language characters and symbols printed on certain keycaps e g french accented characters on the canadian iigs keyboard such as à é ç etc or the british pound symbol on the uk iigs keyboard unlike previous apple ii models however the layout and shape of keys were the same standard for all countries and the roms inside the computer were also the same for all countries including support for all the different international keyboards in order to access the local character set layout and display users would change settings in the built in software based control panel which also provides a method of toggling between 50 60 hz video screen refresh the composite video output is ntsc only on all iigs systems users in pal countries are expected to use an rgb monitor or tvs which featured rgb scart this selectable internationalization makes it quick and simple to localize any given machine also present in the settings is a qwerty dvorak keyboard toggle for all countries much like that of the apple iic outside north america the apple iigs shipped with a different 220 v clip in power supply making this and the plastic keycaps the only physical differences and also very modular in the sense of converting a non localized machine to a local one legacy edit the apple desktop bus which for a long time was the standard for most input peripherals for the macintosh first appeared on the iigs in addition the other standardized ports and addition of scsi set a benchmark which allowed apple for the first time to consolidate their peripheral offerings across both the apple ii and macintosh product lines permitting one device to be compatible with multiple disparate computers the iigs is also the first apple product to bear the new color scheme associated with the brand a warm gray color apple dubbed platinum this color would remain the apple standard used on the vast majority of products for the next decade the iigs is also the second major computer design after the apple iic where apple worked with hartmut esslinger s team at frog design the new corporate color and matching peripherals were used consistently beginning the snow white design language the snow white design language was used exclusively for the next five years the inclusion of a professional grade sound chip in the apple iigs was hailed by both developers and users and hopes were high that it would be added to the macintosh citation needed however it drew another lawsuit from apple corps as part of an earlier trademark dispute with the business arm of the beatles apple computer had agreed not to release music related products apple corps considered the inclusion of the ensoniq chip in the iigs a violation of that agreement developers edit john carmack co founder of id software started his career by writing commercial software for the apple iigs working with john romero and tom hall wolfenstein 3d based on the 1981 apple ii game castle wolfenstein came full circle when it was released for the apple iigs in 1998 37 two mainstream video games zany golf and the immortal both designed by will harvey 38 originated as apple iigs games that were ported to other platforms including the sega genesis pangea software started as an apple iigs game developer naughty dog s first published game was for the 8 bit apple ii the company later developed for the iigs gus edit apple designed the apple iie card to transit apple iie customers to the macintosh lc particularly schools who had a large investment in apple ii software while apple discussed creating an lc plug in iigs card they felt that the cost of selling it would be as much as an entire lc and abandoned it 39 however the educational community had a substantial investment in the iigs software as well which made upgrading to a macintosh a less attractive proposition than had been for the apple iie as a result apple software designers dave lyons and andy nicholas spearheaded a program to develop a iigs software emulator they called gus in their spare time which would run on the power macintosh only 40 41 42 apple did not officially support the project 43 nevertheless seeing the need to help switch their educational customers to the macintosh as well as sell power macs apple unofficially distributed the software for free to schools and other institutions that signed a non disclosure agreement 44 45 46 it was never offered for public sale but is now readily available

based on apple ceo john sculley stating that the iigs would receive a new cpu in 1989 no new computer appeared 53 but in august the iigs started shipping with 1 mb ram in the base configuration vtech makers of the 8 bit apple ii compatible laser 128 announced plans for a iigs compatible computer in 1988 for under 600 54 they demonstrated a prototype in 1989 but the computer was never released
