System 6 Emulator Mac Does Not

I have been using this tool on several large hard drives up to 2GB, both emulated and real, with no issues.

System 6 Emulator Mac Does Not

Mini vMac does not suit my requirements due to lack of serial port emulation.

Basilisk II, despite being a very capable emulator with support for Ethernet, does not officially support 24-bit addressing and hence will not be able to run Mac systems older than 7.5.5, at least not without the MODE32 extension.

Serial emulation, which is what I need, is also supported as well.

This article will describe my various experiments with PCEmacplus and share some interesting findings.

If you are interested, on the same page you will also find emulators for PC XT, Atari, CPM, and other machines.

However, since many exciting features of PCEmacplus such as PPP emulation via the serial port will not be supported on Windows, with some time at hand, I decided to spend some time compiling PCEmacplus for Ubuntu, my favourite Linux distro to be able to explore its full set of features.

After that, install the required X11 and SDL development libraries.

The provided options enable PPP emulation via the serial port (needed for Internet access since PCEmacplus does not emulate the Ethernet card) and enable building with SDL (required for sound support) and with X11 libraries (important, otherwise there will be no video output once the emulator is run).

Finally, although Open Sound System (OSS) has been deprecated in Ubuntu 16, we also enable it with enable-sound-oss just in case.

Emulators built: atarist cpm80 ibmpc macplus rc759 sim405 sim6502 simarm sims32.

Char drivers built: null stdio posix ppp pty slip tcp termios.

This will also install other emulators (atarist, cpm80, ibmpc.

TERM: drivernull ESCESC aspect43 minsize512384 scale1 mouse11 11.

As a start, download the Windows version of PCEmacplus for your favorite Macintosh machine and extract it.

Then create a file call run.sh with the following command, place it into the same folder and execute it.

You will then see two windows one is the emulated Macintosh machine while the other shows various log messages.

You can configure the output method by specifying the driver string in the sound section of the config file.

OSS does not work well on Ubuntu 16, since it has been deprecated.

It either produces no sound at all or plays garbled sounds over the speaker, probably because the frequency and bit rate of devdsp is not configured properly.

However, regardless of which method is used, the Macintosh 128K emulated by PCEmacplus does not play any chime upon booting up only some static noises are heard.

I used Linux dd command to create a 1000MB hard disk image, attach it to the machine using the config file, and use Apple HD SC Setup to initialize the drive and create the partitions.

Surprisingly, despite changing various options, the tool only created a 20MB partition while leaving the rest of the emulated hard drive unallocated.
