Boot SPARCStation 1 in MAME
This article will detail how to boot SPARCStation 1 and install SunOS 4.1.2 in MAME.
The machine will have the following specs:
- Monochrome graphics adapter (there are others, the monochrome one works best)
- 2GB Hard Drive
- 64MB of RAM
The first thing you need to do is download these files and place all of them into the "roms" folder in MAME, except SunOS 4.1.2.
SunOS 4.1.2: https://winworldpc.com/product/sunos/4x (download the one labeled "SunOS 4.1.2 (CD) [Sun SPARC]"
Once that is done you should open CMD or a Linux Terminal and create a virtual hard disk like this:
chdman createhd -f -o sunos412.chd -s 2147483648
Once that's all done the first MAME boot command looks like this:
mame64 sun4_60 -window -slot1 "bwtwo" "-scsibus:0" harddisk "-scsibus:1" "" "-scsibus:6" cdrom -hard sunos412.chd -cdrom SunOS_412.iso
If you want fullscreen, remove the "-window" part.
Then you will see the SunOS boot screen.
Press n and hit enter.
