A later design is now available: SC707

The module has the following features:

• 128k byte RAM memory
• 128k byte FLASH ROM memory
• RAM divided into two 64k byte banks
• RAM bank selected by software
• ROM divided in four 32k byte banks
• RAM bank selected by software or jumpers
• Supports paging of ROM/RAM in lower 32k
• Suitable memory for CP/M 2
• Supplied with Small Computer Monitor in ROM
• SCM includes CP/M loader from Compact Flash
• Two software controlled LEDs
• Compatible with RC2014-Z80 bus
• Standard profile form factor
• Fully functional on 40-pin backplanes
• Works with 40-pin, 60-pin and 80-pin backplanes

This module provides all the memory required to run CP/M 2.2 and is compatible with common RC2014 CP/M distributions. A Compact Flash interface and card is also required to run CP/M, together with a processor, clock and serial port.

This module is not suitable for running RomWBW.

Compatibility

This module conforms to the RCBus specification v1.0 for RCBus-2014 enhanced 39-pin long modules.

The printed circuit board outline conforms to the RC2014 standard for full height modules.

The module is compatible with all RC2014 backplanes, all RCBus-2014 backplanes (RC2014 compatible including SC100 series) and all full RCBus 80-pin backplanes (including SC700 series). Pins in the second row are provided for consistency and mechanical stability.

A similar design SC707 is also available. It is compatible with the RCBus, including the RC2014 standard 40-pin bus, the RC2014 enhanced 60-pin bus and the extended 80-pin RCBus.

The RCBus specification includes RCBus-2014 (both RC2014 standard 40-pin bus and RC2014 enhanced 60-pin bus) and also the full 80-pin RCBus. The 80-pin RCBus provides support for advanced Z80 features, such as the interrupt daisy-chain, as well as support for other processor families.

The Kit

This kit includes all the components needed to make the module, as shown in the first picture. Other modules and backplanes shown in the pictures are not included. You will require tools, solder, and cleaning materials to assemble this kit.

Printed Circuit Board

The printed circuit board is available on its own here.
