A1200 3.9 roms?

[countzero]

3.9 roms are simply 3.1 roms updated with boing bag 2 rom update modules. You can boot into 3.9 straight without reboot caused by romupdate with these.
AFAIK there isn't any legal source to obtain them. You have to burn one yourself or ask someone who can do it.

there is also the OS issue I believe ... moto did you manage to get willem working with anything above XP sp2 ? Something with the XP messes parallel port continously so I couldn't get it working. There is an alternate XP sp1 install on my computer just for willem use.

57 USD from sivava 16 bit eprom adapter included (shipping not included, from Thailand AFAIK.)

I think willem is a good investment if you have some retro stuff lying around. You can also burn roms for your amiga HDD peripherals like a590, a2091, GVP SCSI boards etc, also c64 roms like jiffydos, drive roms and some cartridge roms (games smaller than 8k) are possible.
