I looked at the 785 today, and the expansion cabinet there, but no disk or tape drives were found. As I stated earlier the cpu boards are gone, but there are boards in the BA11-KE. I have a set of 780 boards, but not sure if I have all of the 785 boards. Now the kicker- last time I saw the drives, which I didn't see this time, But I found a Ramtek Marquis model III. I believe it is a graphics processor. It might be able to be sold separately, and is in what seems to be in a H9642 cab. I do not own this, and can make offers. He has a fork lift and can load. I'm not sure if William is willing to transport them and would suggest you contact him directly and he is already planning. If you have any questions feel free to contact me. Located in IL.
