KLESI Low-End Storage Interconnect

The KLESI Low-End Storage Interconnect controllers are a series of device controllers which use MSCP and TMSCP to interface with disks and magnetic tape drives. They include the KLESI-UA (M8739) for the UNIBUS and KLESI-QA (M7740) for the QBUS. The -UA is a quad card which plugs into an SPC slot; the -QA is a dual (although the -S variant is packaged in a quad form, with an S-box handle, for the BA200 series enclosures).

One main use was with the TU81E/TU81-Plus variant of the TU81 magtape drive; it was also used with the RC25 disk drive.
