Point is, it’s not remotely taxing a contemporary computer (even a tiny computer like a Raspberry Pi) to emulate a vintage Macintosh. SheepShaver is no longer supported by its original author, Gwenol Beauchesne, but minor updates are available from an active support forum at Emaculation.com.Okay, a lot of numbers. The most advanced of these emulator programs is SheepShaver. Versions 6 through 9) can only be run through software that emulates Macintosh hardware from 1980s and 1990s. Under Windows, software written for the 'classic' Mac OS (i.e. Project 68k era Mac software and home of the Mini VMac Mac Plus emulatorAn easy way to run 'classic' Mac OS applications under Windows.a customised executable (or “binary”) of the Mini vMac application, usually named “minivmac”, and It also had 128K of ROM (Read Only Memory) that contained all the core software that made it a Macintosh.In order to open a Macintosh Virtual Machine (i.e., an application that emulates an early Macintosh), you’ll need RequirementsThat original Mac Plus had a whopping 1MB of RAM (Random Access Memory), upgradable to 4MB. I’ll describe below how to do this using the Mini vMac emulator, created as part of Paul C. A more practical way is to run a 68k or PowerPC emulator on a modern Mac/Windows/Linux PC.Okay, I assume you’re reading this because you have some interest in emulating a vintage Mac on your own computer.the Getting Started page has helpful documentationThere are also more Mini vMac links on the Vintage Macintosh Resources page. the download page contains binaries for various operating systems I’ve summarised the ROM files required for each model below: ModelRather than me reiterate the voluminous documentation that Mini vMac’s author has accomplished, you can find Mini vMac resources directly from the source: you must have the right ROM for the Mac model you’re emulating, and it must be named correctly (see table below)Fortunately, if Mini vMac starts up and can’t find the ROM file the error message will tell you the name of the ROM file it’s expecting.The Mini vMac project hosts a Mac68k page listing all the Macintosh models and their corresponding ROM file names. the Mini vMac executable and the Mac ROM file must both be in the same directory Download Macintosh ROMs (5.6MB) from Macintosh-ROMs on github Download Macintosh ROM Archive (52.5MB) from the Internet Archive The site also contains information about Mini vMac and links to various sizes of blank Mac disks Download vmac.rom (139K) on sites.google.com. I’ll just point you at where you can find one (or a collection of them):
![]() Classic Emulator Mac Software AndIt’s these options that permit you to select things like target operating system, model of Mac to emulate, screen size, etc. But sometimes I like that tiny Mac SE window too.The mini vMac project provides open source code that allows you to compile the minivmac application using differing command line options. I generally run 1200 x 900 in full colour, as on a Macintosh II with 8MB of memory. If that seems a bit cramped, it’s possible to modify the screen size. On Mac OS X you’d put the minivmac application in the Applications directory, along with the ROM file.Once the emulator has started you’ll see the Mac icon waiting for a startup disk:The above screenshots are from that originally-sized 512 by 342 pixel Mac SE screen, the way things were in 1986. I generally work on a Linux machine so I built some executables for Linux. I’ll cover that next time. It occurred to me that I could make a HyperCard stack to do the same thing for Mini vMac. There’s no magic here.I noted that the Basilisk emulator has a Preferences screen to alter the configuration of the emulation. That way I could try out a Mac SE with the original 512 x 342 pixel screen, or a 1024 x 800 pixel Mac SE FDHD, or a colour Mac II. Computers are so extremely fast and VM technology so good that the guest (the virtual machine) is effectively as fast as the host (the computer hosting the VM). Rather than keeping a Windows machine around or creating a dual-boot machine, I instead use a Virtual Machine or VM.VMs are very common nowadays. EmulationI’ve been a Linux user since the mid-90s, but on occasion I need to use Windows. One “real” difference is that a virtualised Windows guest OS is actually running Windows code from an actual, installed copy of Windows. The language is remarkably similar: the host OS imitates the functions of another OS, the guest. … and I’m simplifying here a lot, yes.What’s the difference between virtualisation and emulation? Not much, really. VMs provide the ability to run a different guest OS, or even the same OS as the host but in a sandbox environment, or with different parameters, or so that it can be quickly discarded after use.Virtualisation technologies go from providing a full desktop UI (using VMWare or VirtualBox), running a “headless” server (using vagrant), or just running an application (like a web service) within a container (e.g., Docker). ![]() So, HyperCard is not dead at all. But the real reason I even bothered to do all this was to be able to once again use HyperCard. When I open up a Mac SE or Mac II window using Mini vMac, use the keyboard shortcut to go full screen, and then start up HyperCard or MacWrite, I can’t even tell the difference: I can do exactly the same things I could do in 1986.I can run a nice, simple word processor like MacWrite or an inventive exploration game like The Manhole. ![]()
