This module conforms to the RCBus specification v1.0 for RCBus-2014 and RCBus-Z80.

SC715 is a Compact Flash Card interface for RCBus. It uses Tadeusz Pycio’s design to correct the timing between the Z80 CPU and the Compact Flash card. http://www.vtsys.pl/interface-compact-flash/

The module is designed to be mounted either horizontally (at the end of a modular backplane) or vertically.

Compatible with CP/M 2.2 and RomWBW, and has been tested with a Z80 CPU at 7.3728 MHz and a Z180 CPU at 18.432 MHz.

Compatibility

This module conforms to the RCBus specification v1.0 for RCBus-2014 and RCBus-Z80.

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. You will also need a Compact Flash card.

Printed Circuit Board

The printed circuit board is available on its own here.
