A parallel input/output module designed for RCBus

This module conforms to the RCBus specification v1.0 for RCBus-2014 and RCBus-Z80. The module contains a Z80 parallel input/output device (Z84C20xx). It provides two bi-directional 8-bit ports, each …

Documentation

Compatibility

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

An RCBus-Z80 compliant backplane is required to create an IEI/IEO interrupt daisy-chain on the backplane rather than wires between modules. Other than that it is fully functional on 40-pin backplanes.

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.

I'm Obsessed with Small Computer Central!

The seller is an amazing computer architect with cutting edge designs. The kits are straight-forward, thoroughly documented, and extremely fun to solder together. I could easily spend much more on Lego and end up with no computers at the end of the project, haha.

I keep coming back for both backplanes and peripherals as previous builds lead me to deeper understanding, unlocking the skill to use new modules. The PIO module is no exception to the modernized, streamlined, and extraordinarily well thought out collection of tools represented by Small Computer Central.

The fact that I can only solder each board one time means I'll be coming back for almost every component available just for meditative solder projects; and I'm sure I'll have similarly glowing reviews for all of them, given my experience with the systems so far.

As I mentioned to the seller, the latest models in the SC700 and SC500 lines have silk screens that are pretty much completely self-documenting at this point; improving on earlier models like the SC140, an already magnificent Z180 SBC build for the Z50Bus backplanes.
