KarstLedger 5.5

Strata Software, 1982. Application software for the PDP-11.

Description

An accounting package for the PDP-11, written by Strata Software for small businesses.

Provenance

Sent to Lazarus by post, with a note asking whether anything could be saved. The disks had been stored beside a loudspeaker, and one track on each was weak. Only fragments could be read. They are kept because nothing else of the work survives.
