Macintosh 128K, initially published as Apple Macintosh, is the native Apple Macintosh PC computer, the Macintosh was launched by the now-famous $370,000 (equivalent to $871,550 in 2017) TV ad by Ridley Scott, "1984", which was broadcast primarily in the third trimester of Super Bowl XVIII on January 22, 1984 on CBS.
6 ] Macintosh selling has been high since its first publication on 24 January 1984 and amounted to 70,000 copies on 3 May 1984. After the publication of its follower, the Macintosh 512K, it was renamed Macintosh 128K. There have been no Apple offers for upgrading your memory. In contrast to the Apple II, no lists of Macintosh system ROM sources were provided.
Macintosh memory was made up of sixteen 4164 64k×1 RAMs. Rear case of an unchanged Macintosh (sold January-November 1984). Models manufactured after November 1984 carry the "Macintosh 128K" tag on the back of the case. 8 ] The extension and cross-linking was carried out via two non-standard RS-422 DE-9 interfaces with the names "Printer" and "Modem", which did not provide handshake capability.
You can add an additional removable disc device via a 19-pin D-Sub connection. There were no arrows, decimal keys, or functional keys on the initial keyboards. It was a deliberate choice by Apple, as these keys were customary on older plattforms, and it was assumed that adding these keys would be an encouragement to program engineers to just migrate their legacy application to the Mac instead of developing new ones according to the GUI Paradigm.
Later, Apple provided a numerical control panel for the Macintosh 128K. Keyboards shipped with the newer Macintosh Plus models would contain the digital keys and arrows, but still no feature keys. Like the Apple Lisa before it, the pointer had a unique key. The Apple also had its 300 and 1200 bit/s modem available, which were initially approved for the Apple II line.
Originally, the Apple ImageWriter was the only available desktop printing device, a point array device developed to generate 144 dots per inch of WYSIWYG from the 72 dots per inch Mac display. Macintosh included a 400 K-byte, single-sided 3 1-inch disc mechanism that reserved no room for other intern mechanic memories. Because of the 128 kilobyte limitations of the Macintosh and the fact that the diskettes could accommodate 400 kilobytes, diskettes often had to be swapped into and out of the discrive.
Therefore, often disk ette diskettes were used. Macintosh's Macintosh drive (mechanically the same as the Macintosh's own drive, piggybacked on the same controller) was a favorite $495 add-on. Third parties were much more costly and usually plugged into the slowed down Apple specified interface, although some vendors opted for the fast, non-standard diskette interface.
128K can only use the Macintosh file system for saving. Macintosh was delivered with the very first system and finder app known to the general population as " System 1 ". Macintosh was updated three times before it was set. We recommend System 2. The Macintosh 128K version 0 has formally been removed from Macintosh 128K disk format because it was spread over 800 KB of floppies that could not be used by the 128K.
Among the available development tongues were McBASIC, MacPascal and the Macintosh 68000 Development System. The Macintosh also came with a handbook and a one-of-a-kind led tours cartridge that worked together with the led tours disk as a guide for both the Macintosh itself and the packaged programs, as most new Macintosh players had never used a Mac keyboard before, let alone tampered with a GUI.
For the Macintosh, the 512K's enhanced memory was critical as it enabled more efficient application development, such as the then beloved Microsoft Multiplan. Apple, however, marketed the 128K for over a year as the entry-level computer, the medium 512K and the high-end Lisa (claiming that it could expand slightly if the end users ever needed more RAM).
Job explained that because "customization is now really mainly software...most features in other machines are on the Mac," unlike Apple II, the Macintosh didn't need 128K slotting, which it described as expensive and required bigger sizes and more performance. 15 ] It was not expandable by the users and only Apple Technical Center were allowed to open the case.
They were all externally mounted, such as the MacCharlie, which added IBM computerompatibility. There was no way to add in-house memory, more random access memory or upgraded memory boards, but some of the Macintosh engineer rejected the idea of jobs and clandestinely created work-arounds for them. For example, the Macintosh should have only 17 headers on the board, enough to have 128k system RAM supported, but the engineering staff added an extra two headers without Jobs' knowing, which made it possible to extend the computer to 512k even though the real act of system RAM upgrades was challenging and the piggyback ing of extra random access memory beyond the 4164 on-board chip was necessary.
Apple published an offical F512k calculator in September 1984, after month-long complains about the Mac's lack of working space. At the time the Mac 512 came out, Apple renamed the Genuine Mac to "Macintosh 128k" and changed the mainboard to allow simpler random access up-grades. However, the difficulties of installing code in the confined free space, combined with the new interfaces and the event-driven program paradigm, disheartened the vendor to support it, so that the 128K could do with a relatively small codebook.
While the Macintosh Plus and to a smaller degree the Macintosh 512K are compatibly with much later versions of Macintosh applications, the 128K is restricted to applications developed specifically for this purpose. Standard Mac 128K with the 64K ROM is not compliant with Apple's 800 KB HFS drives or Apple's 20 hard disk.
Mac 128K that has been updated with the newer 128K ROM (called Macintosh 128Ke) can use HFS enabled 800 KB drive and HD20 enabled hard disk drive. Originally the Macintosh was uncommon in that it contained the Macintosh department signature from the beginning of 1982, formed on the inside of the case.
