Mac Plus Game Floppy

| Posted on by

Note that 9 times out of 10 on an old 128k, 512k, or Mac Plus, the eject mechanism in the drive will be seized up over time. You will be able to insert a disk once, and it will not eject. You must disassemble the machine and the drive and loosen up the old grease, and often replace the gear that has broken. 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.

I wanted to extend my vintage computer collection with a classic, all-in-one Macintosh for a long time. Unfortunately, they are not so common in Europe as in the US and the costs of the shipment are often higher than the computer itself. Sometimes you may find something on the local auction portal, but usually it costs a lot.

That’s why I was really happy to find a Macintosh Plus in an attractive price. However, the low cost was justified — according to the description, the screen was dead, it also lacked of the mouse and the keyboard. Who cares, I’ve got it anyway. The worst case scenario — I’ll get a modern art sculpture.

Fixing the screen

So, the first thing to fix was the screen. I hoped that it’ll be enough to turn the brightness knob, but it wasn’t the case. Internet forums and the amazing book about fixing classic Macs — Macintosh Repair and Upgrade Secrets — suggested that the black screen is often a symptom of the cold joints in J4 connector. I get all of my engineering skills and touched the offending pins with the solderning iron:

After switching the Mac on, it presented a beautiful icon of floppy disk with blinking question mark:

So I bought this little guy last week. It had broken display and I've just fixed it with the soldering iron like a freaking MacGyver! pic.twitter.com/0FkbgleC8k

I’d never been happier in my life and danced around the room seeing this icon :) An interesting thing that I also found in the Mac was this box of old batteries:

Apparently the previous user tried hard to keep the internal clock powered, without the original battery.

Mouse

You can’t do much on a Mac without a mouse. The Mac Plus uses a different kind of mouse than PCs or even later Macs. Some people were able to convert an old, ball mouse so it’s compatible with Mac Plus. However, it seems that it’s much easier to use Amiga or Atari ST mouse - it have the same internals, the only difference is pinout. Two DB9 male connectors and a bunch of cables did the trick:

I guess that you can also connect an USB mouse, using the USB-to-Amiga mouse converter (eg. Jerry and the custom DB9 pinout as above).

Floppies

At this point I was able to move the mouse pointer on an empty screen with a blinking floppy icon. In order to move things forward, I needed a system. One option is the Rescue My Classic Mac webpage offering a complete set of floppy disks, containing system, games and disk utilities.

I took a different path and asked on a Polish Facebook group dedicated to the old computers and game consoles. In a few hours I was contacted by a few people offering their help. Eventually, I’ve got the system disk (and the Lemmings game) from Paweł - thanks!

Memory

Mac Plus memory can be easily upgraded from 1 to 4 MB. All you need is a bunch of old 1MB SIMM modules (preferably with 8 or 9 chips). I’ve bought 4 such modules ($1 per module), installed it in the Mac and cut the resistor leg:

The last part was a bit scary (what if the RAM doesn’t work?), but everything went fine and now I can enjoy 4 times bigger RAM:

Keyboard

In case of computers like Macintosh Plus, with its innovative GUI, the mouse is much more important than keyboard. Still, sometimes it’s good to type something and my Mac lacked of the keyboard. As you may guess, it’s not a standard PS2/USB/ADB keyboard, but a device specific to Mac 128k/512k/Plus models. It also has a strange connector - the same as for old phone sets.

Using resources available in the internet, like this blog post and Mac Plus technical information I was able to create an Arduino-based converted that allows to use a PS/2 keyboard with Mac Plus. I think it’s pretty neat:

The project can be found on my Github.

Hard drive

Macintosh Plus, unlike the later models, comes without a built-in hard drive. Floppy disk drive is the default storage device and it isn’t great at all — unreliable, slow and offering little space.

The computer has a SCSI port, so we can connect an external storage. External SCSI hard drives (even the old and small ones) are a bit pricey, but there’s an interesting alternative: IOmega ZIP drive. It’s often used as the main storage for the classic Macs and 100 MB of the disk space it offers on a single floppy is more than enough.

After reading a ton of blog posts and forum discussions, I decided to use the IOMega ZIP Init 4.2 driver to format the drive. Another collegue from the retro group offered his help. Using his Powebook 150 I created the floppies containing System 6.0.8 and the driver. Now I was able to install the system on ZIP. It booted happily!

The aforementioned Rescue My Classic Mac also offers the floppies containing System installation and IOMega driver, in 800k format. It may help if you don’t have any classic Mac equipped in the HD drive nearby.

Serial port connection

Macintosh Plus is unable to read PC-formatted floppies (even 720k), so I had to find another way to exchange data with my MacBook Pro. I decided to use the serial port connection. Mac uses Mini Din-8 RS-422 standard, but it can be easily connected to the DB9 serial port. For some reason the X/Y/ZModem file transfer didn’t worked, so I was forced to transmit files as binhex-encoded text. It’s very slow, but works and allows to communicate with Mac.

Result

So, from a blank-screened, mouse- and keyboard-less Mac Plus I’ve got this machine:

The final specs are as follows:

  • Macintosh Plus,
  • System 7.0.1,
  • 4 MB RAM,
  • Amiga mouse connected via adapter,
  • PS2 keyboard connected via Arduino,
  • IOmega 100 MB ZIP used as a hard drive.

It’s an amazing machine and I feel that amount of the work and time I have to spent to get to this state makes it even greater. Probably if I’d bought a slightly newer Macintosh SE/Classic, containing an internal hard drive and the standard ADB ports I wouldn’t have to deal with all of these issues myself. But I don’t regret any second working on it :) I’m just glad that I was able to put one of these little computers back to life.

Introduced in January 1986, two years after the original Macintosh, the Mac Plus shipped with 1 MB of RAM, a new double-sided 800 KB floppy drive, and a built-in SCSI port (the first Mac so equipped). Not only was 1 MB more RAM than PC-class machines could handle, but the Plus could be expanded to 4 MB total RAM! (Earlier Macs came with a fixed amount of memory with no upgrade path.)

The SCSI bus on the Mac Plus is officially rated at 1.25 MBps/10 Mbps by Apple, although real world testing shows it to be barely over 0.26 MBps/2.1 Mbps – which is still 4x the speed of Apple’s earlier floppy port hard drive.

The Plus does not support high density floppies, but it can be used with an external high density floppy drive as long as the disks used are 800K floppies.

The original Plus came in Apple beige; during 1987 the case color was changed to platinum, the same color used for almost all post-1986 desktop Macs until the iMac arrived in 1998 (there were a couple black Macs). There are persistent rumors that the power supply in the beige Plus was less reliable and more prone to failure with 4 MB configurations, a problem addressed with an improved power supply in the “platinum” Plus.

The Mac Plus was bundled with MacWrite and MacPaint, and Apple began to bundle HyperCard and MultiFinder in August 1987.

Until the air cooled iMacs came out, all desktop Macs following the Plus and 512Ke up until the slot-loading iMacs have included a fan to reduce internal heat. Because the Mac Plus is convection cooled, you should never block the vents on the side or top of the computer.

Those used to newer Macs will find several keys missing from the keyboard: Esc and Ctrl, along with the Cmd and Option keys to the right of the space bar are simply not there. Neither is the power key, which existed on all Apple ADB keyboards and the first-generation USB keyboard.

The Plus and 512Ke were the last Macs not to use ADB ports for the keyboard and mouse – and the first to use mini DIN-8 serial ports. Discontinued in 1990, the Mac Plus had the longest product life of any Macintosh.

The Mac Plus had a minor role in Star Trek IV: The Voyage Home.

On March 17, 1987, Apple pulled six units and declared them “the one millionth Macintosh”, giving these to Jef Raskin, Steve Wozniak, and others. (Apple Confidential 2.0, p. 98)

The Plus can become a reasonable Web server, as the Macintosh Plus Web Server demonstrated until it was retired in October 2001.

You can convert a non-working compact Mac into a Macquarium. (Please, don’t even think of converting a working one – you can always find someone interested on the Classic Macs or Vintage Macs lists.)

Tips

  • If you have less than 4 MB installed, upgrade to 4 MB. You can often find pulled 1 MB SIMMs (removed from other Macs during upgrade) inexpensively.
  • The Plus cannot use 2-chip 1 MB SIMMs.
  • Memory permitting, set the disk cache to 128k.
  • When a Plus is started-up, it loads the first system it finds in this order: floppy; SCSI ID 6, 5, 4, 3, 2, 1, 0. If you have a drive partitioned, and both partitions have a System Folder, it loads the partition that comes first alphabetically.
  • To use HD floppies, look into the Applied Engineering AE HD+ external floppy drive. They are sometimes available on the used market. Note that the “plus” is important – the AE HD will not do the job.
    You can download drivers for the HD+ drive from the Mac Driver Museum.
  • Rapport, a device called by Kennect Technology, allows you to access 720K DOS disks on a Plus. It attached to the drive port.
  • Because of limited SCSI throughput, older hard drives with no buffer should normally be formatted with a 3:1 interleave for use with the Plus. (Unfortunately, other Macs may find it difficult or impossible to work with this interleave.) This is not an issue for newer drives with data buffers.
  • If you use FWB Hard Disk Toolkit to format your hard drive, be sure to turn off command linking. “The Plus can go a little daft with it on.”

Cautions

  • Never connect an Apple II 5.25″ floppy drive to the Mac’s floppy port. Doing so can ruin the floppy controller, meaning you can’t even use the internal drive any longer.
  • That monitor packs a lot of voltage. Read Compact Mac CRT Energy before working inside.
  • The Mac Plus does not provide SCSI termination power, depending on external SCSI devices to provide it. For more details, see SCSI Termination Power.
  • Macs with black-and-white only displays (1-bit, no grays) may find Netscape Navigator 3 makes it impossible to view some pages and sites. The workaround is to use Navigator 2.
