The range of RCBus 80-pin prototyping modules has been extended, including an extra large module with two RCBus headers, allowing a 160-pin backplane system to be created or to bridge two RCBus systems.

SC734 is a new Micro SD storage module for the RCBus. Full support is included in RomWBW 3.5 and later.

I have recently been using Shiela Dixon’s TMSEMU3 graphics card module for the RCBus. I highly recommend this module. More details…

Many Z80 parts are no longer being manufactured and stocks at major distributors are mostly exhausted.

In order to continue supplying kits with retro appropriate (1980’ish) genuine new parts I have purchased a good stock of the Z80 CPU and the Z80 SIO/2.

To help other enthusiasts I have listed some of these in the components section of the Small Computers Direct store.

The SC600 series of 40-pin RCbus backplanes and modules is now available.

The SC600 series of 40-pin RCbus backplanes and modules will be released soon.

The following new RCBus-80pin modules have recently been released:

• SC729 – Compact Flash Module
• SC730 – Z80 CPU plus MMU
• SC732 – Dual Channel Servo Module

These modules should be releaased soon:

• SC731 – Dual Channel PWM Module
• SC732 – Prototyping module
