It turns out I've got a few mass storage controller which might be of use. All were funcional when removed from their previous homes. Cipher Data products - 2-board set + controller formatter (on the format of the open reel tape drive, rather than the S-100 board pair) 9-trackTape interface - XComp 8" Winchester Disk Controller board pair tuned for the 4.34 MHz data transfer rate of SA-100x series drives. - MSC - (later called Xebec) S-100, unfortunately over-height ST-506 (2 drives) interface, MFM coding. - Ditronics-1 (Micro Applications, Inc) dual density FDC (5-1/4" drives only) Let me know if you have any use for these items, and perhaps we can arrange a transfer.
