Mosaic Copy 4.5

Port Brookby Software, 1998. Application software for IBM mainframes.

Description

A disk utility for IBM mainframes, sold to repair shops by Port Brookby Software.

Provenance

Transferred from the backlog of unread media at a partner archive. The tape had stretched near its start; the first blocks were repaired by hand from the sampled signal. Only fragments could be read. They are kept because nothing else of the work survives.

Access

Free, in the Lazarus reading room in Vancouver and in partner reading rooms. The license does not permit copies to be taken away.

In the reading room it runs in emulation under profile LZE-MVS-3, from a read-only copy of the recovered image, as it would have on IBM mainframes.
