SC118, v1.1, Software, CP/M

A version of CP/M 2.2 is available for SC118, Z80 Processor card.

New versions, together with more detailed instructions, are available here.

This version is specifically for SC118 (Z80 Processor card) plus SC125 (Serial and timer card), with the Small Computer Monitor v1.0 configuration F1 in ROM.

It supports the two serial ports on serial card SC125, and the Compact Flash interface card SC127. CP/M uses the serial ports with the settings supplied by the Small Computer Monitor.

The CP/M software is supplied (below) in the form of a “PutSys” program. This program is loaded and run from the Small Computer Monitor and installs CP/M to a formatted Compact Flash card. Once installed to Compact Flash, CP/M can be started with the command “CPM”, from the Small Computer Monitor.
