OS disk for S900 with IB-101A

Hello everybody. I'm searching for OS disk for my Akai S900 that supports the IB-101A Atari-HD-board. As I found out it is OS V.3.0 or a modified version of OS 4.0 or 2.0. Can anyone point me in the right direction or maybe has a image-file or can sell me a copy of that disk ? thanks a lot.

A quick google search yielded this link to 4.0 - http://akai-s900.blogspot.co.uk/2008/02 ... -s900.html

Not sure if it's the modified version that you're looking for but it's worth a shot.

Alternatively shoot these guys an email - http://www.circuitbenders.co.uk/contact.html

I've bought S3200XL eproms from them in the past, maybe they can point you in the right direction
