MacDraw II (1988) was a complete rewrite of the original MacDraw. It was developed at Apple by project leader Gerard Schuten and team members Amy Goldsmith and Marjory Kaptanoglu, and was released by Claris. MacDraw II introduced color and many other missing features and was also enhanced for the Macintosh II. NoiseTorch is an easy to use golang open source application for Linux with PulseAudio. It creates a virtual microphone that suppresses noise, in any application. Use whichever conferencing or VOIP application you like and simply select the NoiseTorch Virtual Microphone as input to torch the sound of your mechanical keyboard, computer fans, trains.

MacDraft PE includes nearly all the features of its more powerful sibling, such as drafting tools for lines, fills, dimensions, and more. And with a conceptual lineage that goes back to the original MacPaint and MacDraw, MacDraft has a familiar Mac interface that is very easy to learn and fun to use.

The Macintosh Plus computer is the third model in the Macintosh line, introduced on January 16, 1986, two years after the original Macintosh and a little more than a year after the Macintosh 512K, with a price tag of US$2599.^[1] As an evolutionary improvement over the 512K, it shipped with 1 MB of RAM standard, expandable to 4 MB, and an external SCSI peripheral bus, among smaller improvements. Originally, the computer's case was the same beige color as the original Macintosh, Pantone 453,^[2] however in 1987, the case color was changed to the long-lived, warm gray 'Platinum' color.^[3] It is the earliest Macintosh model able to run System 7.

Overview[edit]

Bruce Webster of BYTE reported a rumor in December 1985: 'Supposedly, Apple will be releasing a Big Mac by the time this column sees print: said Mac will reportedly come with 1 megabyte of RAM ... the new 128K-byte ROM ... and a double-sided (800K bytes) disk drive, all in the standard Mac box'.^[4] Introduced as the Macintosh Plus, it was the first Macintosh model to include a SCSI port, which launched the popularity of external SCSI devices for Macs, including hard disks, tape drives, CD-ROM drives, printers, Zip Drives, and even monitors.^[5] The SCSI implementation of the Plus was engineered shortly before the initial SCSI spec was finalized and, as such, is not 100% SCSI-compliant. SCSI ports remained standard equipment for all Macs until the introduction of the iMac in 1998.

The Macintosh Plus was the last classic Mac to have a phone cord-like port on the front of the unit for the keyboard, as well as the DE-9 connector for the mouse; models released after the Macintosh Plus would use ADB ports.

The Mac Plus was the first Apple computer to utilize user-upgradable SIMM memory modules instead of single DIP DRAM chips. Four SIMM slots were provided and the computer shipped with four 256K SIMMs, for 1MB total RAM. By replacing them with 1MB SIMMs, it was possible to have 4MB of RAM. (Although 30-pin SIMMs could support up to 16MB total RAM, the Mac Plus motherboard had only 22 address lines connected, for a 4MB maximum.)

It has what was then a new 3+1⁄2-inch double-sided 800 KB floppy drive, offering double the capacity of floppy disks from previous Macs, along with backward compatibility. The then-new drive is controlled by the same IWM chip as in previous models, implementing variable speedGCR. The drive was still completely incompatible with PC drives. The 800 KB drive has two read/write heads, enabling it to simultaneously use both sides of the floppy disk and thereby double storage capacity. Like the 400 KB drive before it, a companion Macintosh 800K External Drive was an available option. However, with the increased disk storage capacity combined with 2-4x the available RAM, the external drive was less of a necessity than it had been with the 128K and 512K.

The Mac Plus has 128 KB of ROM on the motherboard, which is double the amount of ROM in previous Macs; the ROMs included software to support SCSI, the then-new 800 KB floppy drive, and the Hierarchical File System (HFS), which uses a true directory structure on disks (as opposed to the earlier MFS, Macintosh File System in which all files were stored in a single directory, with one level of pseudo-folders overlaid on them). For programmers, the fourth Inside Macintosh volume details how to use HFS and the rest of the Mac Plus's new system software. The Plus still did not include provision for an internal hard drive and it would be over nine months before Apple would offer a SCSI drive replacement for the slow Hard Disk 20. It would be well over a year before Apple would offer the first internal hard disk drive in any Macintosh.

A compact Mac, the Plus has a 9-inch (23 cm) 512 × 342 pixel monochrome display with a resolution of 72 PPI, identical to that of previous Macintosh models.^[6] Unlike earlier Macs, the Mac Plus's keyboard includes a numeric keypad and directional arrow keys and, as with previous Macs, it has a one-button mouse and no fan, making it extremely quiet in operation. The lack of a cooling fan in the Mac Plus led to frequent problems with overheating and hardware malfunctions.

The applications MacPaint and MacWrite were bundled with the Mac Plus. After August 1987, HyperCard and MultiFinder were also bundled. Third-party software applications available included MacDraw, Microsoft Word, Excel, and PowerPoint, as well as Aldus PageMaker. Microsoft Excel and PowerPoint (originally by Forethought) were actually developed and released first for the Macintosh, and similarly Microsoft Word 1 for Macintosh was the first time a GUI version of that software was introduced on any personal computer platform. For a time, the exclusive availability of Excel and PageMaker on the Macintosh were noticeable drivers of sales for the platform.

The case design is essentially identical to the original Macintosh. It debuted in beige and was labeled Macintosh Plus on the front, but Macintosh Plus 1 MB on the back, to denote the 1 MB RAM configuration with which it shipped. In January 1987 it transitioned to Apple's long-lived platinum-gray color with the rest of the Apple product line, and the keyboard's keycaps changed from brown to gray. In January 1988, with reduced RAM prices, Apple began shipping 2- and 4- MB configurations and rebranded it simply as 'Macintosh Plus.' Among other design changes, it included the same trademarked inlaid Apple logo and recessed port icons as the Apple IIc and IIGS before it, but it essentially retained the original design.

An upgrade kit was offered for the earlier Macintosh 128K and Macintosh 512K/enhanced, which includes a new motherboard, floppy disk drive and rear case. The owner retained the front case, monitor and analog board. Because of this, there is no 'Macintosh Plus' on the front of upgraded units, and the Apple logo is recessed and in the bottom left hand corner of the front case. However, the label on the back of the case reads 'Macintosh Plus 1MB'. The new extended Plus keyboard could also be purchased. Unfortunately, this upgrade cost almost as much as a new machine.

The Mac Plus itself can be upgraded further with the use of third-party accelerators. When these are clipped or soldered onto the 68000 processor, a 32 MHz 68030 processor can be used, and up to 16 MB RAM. This allows it to run Mac OS 7.6.1.^[7]

There is a program available called Mini vMac that can emulate a Mac Plus on a variety of platforms, including Unix, Windows, DOS, classic Mac OS, macOS, Pocket PC, iOS and even Nintendo DS.

Long production life[edit]

Although the Macintosh Plus would become overshadowed by two new Macintoshes, the Macintosh SE and the Macintosh II in March 1987, it remained in production as a cheaper alternative until the introduction of the Macintosh Classic on October 15, 1990. This made the Macintosh Plus the longest-produced Macintosh ever, having been on sale unchanged for 1,734 days, until the 2nd generation Mac Pro, introduced on December 19, 2013, surpassed the record on September 18, 2018. (it would ultimately last for 2,182 days before being discontinued on December 10, 2019) (Second to the Mid 2012 13 inch (unibody) Macbook Pro that has been on sale from June,11,2012 to October,27,2016 spanning 4 years, 4 months, and 16 days this macbooks holds the title of the longest-produced MacBook Pro ever) It continued to be supported by versions of the classic Mac OS up to version 7.5.5, released in 1996. Additionally, during its period of general market relevance, it was heavily discounted like the 512K/512Ke before it and offered to the educational market badged as the 'Macintosh Plus ED'.^[8] Due to its popularity, long life and its introduction of many features that would become mainstays of the Macintosh platform for years, the Plus was a common 'base model' for many software and hardware products.

Problems[edit]

The lack of fan could cause the life of a Macintosh Plus to end early for some users. As the power supply would heat up, solder joints inside it would fracture causing many problems, such as loss of deflection in the monitor or a complete loss of power. As in most early compact Macs, the problem was common in the yoke connector, flyback transformer, and horizontal drive coupling capacitor.^[9] A fan was also often added to reduce heat when the machine was upgraded to its full RAM capacity of 4 MB.^[10]

From the debut of the Macintosh 128K through the Macintosh Plus, various third-party cooling add-ons were available to help increase airflow through the unit. Apple reorganized the compact Macintosh case to accommodate a fan with the release of the Macintosh SE, which optionally included a heat-generating internal hard disk.

ROM revisions[edit]

The Plus went through two ROM revisions during its general market relevance. The initial ROM was replaced after the first two months as it had a serious bug which prevented the Mac from booting if an external SCSI device was powered off. The second revision fixed a problem with some SCSI devices that could send the Mac into an endless reset at POST.^[11]

Introduction

For a long time, there was no really practical way to import MacDraw files inPC applications. Our best bet was till recently to import the MacDraw picturesin a Word for Mac file, to export these files as Word for Windows files from MacWord (not in Word for Windows, since the Windows conversion module, up to version6, strips all Macintosh graphics in the imported file) and to open them on thePC. This method was rather painful.

The PDF Way

The latest solution proposed by a visitor to transfer MacDraw files to the PC is so simple that nobody had found it till now! Print to PDF from MacDraw, then open the resulting file in Acrobat Reader and even in Illustrator of Photoshop, since latest versions of those packages can open (and edit) the PDF files. One finds new ways to use Acrobat and the PDF format every day!!
Thanks to Anne for the tip.

Claris Impact and Claris Draw for Windows

Claris, ex-subsidiary of Apple Inc. in charge of application software development, launched some Windows packages which should simplify our task. More precisely, it happens that MacDraw files can be imported in Claris Draw for Windows and in Claris Impact. From there, you could use the clipboard to paste the picture in any package, or export in some supported formats. Claris Draw can export files as CGM [Computer Graphics Metafile], PCT [PICT, a format widely used on the Macintosh] and WMF [Windows MetaFile]). If you install a PostScript printer, you can also print to a file and select the EPS option. Last, but not the least, Adobe Acrobat could also be a solution.
Beware, those software packages are not so easy to find, and you could even hear Claris representatives saying they don't exist! Check the mail order houses, first those having a Macintosh and a PC catalog.
Since Apple took over the whole software catalog of Claris, now called FileMaker Inc., it seems that there is no future for the Draw package. If you can buy a copy from somebody, do it!

Claris Solution

Things are never easy. You can't just copy the MacDraw files on a PC floppy or from a Mac floppy on the PC hard disk, because MacDraw uses both forks of the Macintosh file (see our page on file forks for more information on this).
Claris support desk recommends to use an utility dubbed 'Convert2Dos' which can be downloaded from their ftp site. This is an archive compacted with Stuffit. You have to decompress it on a Mac and run it to create from each MacDraw file a set of two files, one with the .MDP extension and the other with the .RES extension. The documentation also says to use only eight character file names, but it doesn't matter. The only condition is that both files should have the same name.
As you surely guessed, I was very eager to see what this utility really did. The RES extension let me think they copy the resource fork in this file. This holds true. The MDP file should therefore be the data fork. No sir! By mistake or by purpose, the utility copies both forks to this file and changes the filename inside the file (it appears that it doesn't matter, anyway).
These files, brought on a PC, can be opened in the Claris Draw program, which converts the picture and propose to save it in a third file, bearing the CDD extension.

How to Do the Same Thing with MacDisk?

You can do the same thing with our utilities. We didn't implement a specific treatment for MacDraw files, it would have been overkill.
You can copy successively the MacDraw files with the data copy option and with the resource copy options. This way, you get the two sets of files with the correct contents. You just have to give them the extensions that Claris Draw for Windows is expecting.
You could also correct the extensions/signatures table with SignEdit, putting the extension MDP for the signature 'dPROdDOC' (signature of MacDraw Pro).
You then make a first copy of the file(s) in the normal mode (first item in the menu 'Options'). You get a file with the MDP extension. Now, you change the copy mode ('Resource Copy' in the menu 'Options') and copy the file(s) a second time. Since a file already exists under the same name, the program will create a file with a numeric extension ('001', etc.). You only have to rename these files with the correct extension (RES).
All you have to do now is opening the files in Claris Draw.

Partial Automatic Solution

It is also possible to automate the process to a certain extent. This is useful under Windows 95, because the Explorer often hides the extensions by default. You begin copying the files to the PC as MacBinary files (item 'Binary Copy' in the menu 'Options'). In this mode, the program copies a header, the data fork and the resource fork to a single file. All elements of the MacDraw file are kept together. Then, you use a special utility to automagically create both files with the correct extensions (see above).

You can download this utility, called SplitDraw. Its use is pretty simple. Just select the container file and start the operation. SplitDraw do some sanity checks and will refuse to split a file which is not in the MacBinary format.

Solutions on the PC

Canvas for the Macintosh can open MacDraw files and should be able to save them in another usable format.
We don't know if it works also for MacDraw files after transferring them to the PC (still another fork problem).

Other Programs Opening MacDraw Files

Macdraw Replacement Parts

A practical solution is to open the files in Claris Draw or MacDraw and toexport to PICT files. Those PICT files can be used asis or as models to redraw.
Recent versions of Illustrator can open those PICT files,a ccording to a recent visitorof the site.
A customer reported that he had good results placing those PICT files inPowerPoint for Mac, then transferring the files to a PC(with our MacDisk or using MS-DOS floppy disks) andreopening them in PowerPoint for Windows. The images were still editables.
On the other hand, Photoshop opens PICT files.

Software Packages on the Macintosh

Macdraw Replacement Cushions

Canvas can open MacDraw files and should be able to save them in another usable format.
On the Macintosh, MacDraft can open MacDraw files and export them to another format.
We could not test both packages directly.
