intel MSD-720

Hi I believe this is the same drive box I got from Eric Smith in trade a few years back. If so, it was intended to go under a Series II MDS computer and as was mentioned was connected to a double density card set. This was the double density M2FM that Intel adopted ( thinking that IBM was going to adopt but didn't ). I was told that the drives have a slightly higher frequency response than the regular SA800's. Other than that, they are just drives and power supply. As I said, they were form fit to sit under the Series II. The Series II had an internal single density drive but most wanted the greater density for developement work. When I worked for Intel, I was responsible for the test of the data separator card that was part of the pair of cards used The orther card was a bit slice using 3000 series bitslice to run the states of the controller. It would be cool if it came with the cards as well. These can be plugged into any multibus as a disk controller. Dwight
