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
Rough guide
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.
sun4_60.zip - https://wowroms.com/robots.txt/roms/mame/sun-4-3x0-clone/108220.html
bwtwo.zip - https://archive.org/download/aristmk6_201810/bwtwo.zip
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.
