EuroCard Bus Boards

The tables below summarize the boards created by RBC members using the EuroCard Bus (ECB). Note that some of the processor cards also function as Single Board Computers - a useful feature for users wishing to bootstrap a new ECB system.

ECB Backplanes

Board NameDescription/Features
ECB Mini Backplane A 3-slot EuroCard Bus Backplane
Backplane-8 An 8-slot EuroCard Bus Backplane
Extended Backplane-12 A 12-slot EuroCard Bus Backplane
12-Slot Backplane for Siemens 505-6508 A 12-slot EuroCard Bus Backplane with a form factor specifically designed to fit in a readily available Siemens 505-6508 chassis box


ECB Processor Boards

Board Name Description/Features
KISS-68030 A Motorola 68030 processor board. Requires the Multifunction Controller (MF/PIC) board for I/O (see below). This is a new board under active development as of late 2015.
MINI-68K A Motorola 68008 processor board. Requires the Multifunction Controller (MF/PIC) board for I/O (see below).
SBC-188 An Intel/AMD 80C188 processor board. Capable of functioning both as an an SBC and on the ECB bus.
Mark IV A Zilog Z180 processor board. Capable of functioning both as an an SBC and on the ECB bus.
SBC V2 A Zilog Z80 processor board. Capable of functioning both as an an SBC and on the ECB bus.
6x0x-ATX-6U An MOS 6502 / Motorola 6809 processor board. Electrically capable of functioning both as an an SBC and on the ECB bus, but ECB software support currently limited
N8 A Zilog Z180 processor board. Electrically capable of functioning both as an an SBC and on the ECB bus, but ECB software support currently limited

ECB Input/Output/Memory Cards

Board Name Description/Features
PropIO A Propeller-based I/O board that provides keyboard, video, and SD Card storage.
4PIO The ECB-4PIO board contains 4 Z80A-PIO and the complete Bus-Control-Logic for the ECB-Systembus conform to KONTRON
ModPrn ECB-PCB to communicate with SBC V1, SBC V2 or any other developed Z80-CPU to outside the Computer system (Serial communication, Communication via Modem) or to use serial Printers with RS232/V.24-Interface
RamFloppy A RAM Floppy does not use the local memory resources of the processor, but instead is implemented as an external storage subsystem, which may functionally appear as being similar to a floppy or modest hard drive.
Color VDU A traditional video display board with color capability. Provides 80×25 text and will drive VGA displays that are capable of EGA display frequencies. Also includes a keyboard and mouse interface.
Dual SD Card A board providing Dual SD Card storage
DiskIO V3 A board providing floppy and IDE storage support
MF/PIC Multifunction Programmable Interrupt Controller support board required by the ECB Mini-68K CPU and ECB KISS-68030 CPU boards. It may also be used with the SBC v2 (Z80) to provide mode 2 interrupt vectoring.
ADIO An Analog/Digital I/O Board
DSKY A Display Keyboard unit providing a hexidecimal display and numeric input keypad.
Cassette Interface Allows for storage/retrial of files on cassette tapes using the Kansas City Standard
USB FIFO A EuroCard Bus board providing a fast interface between ECB machines and modern PCs over USB.


ECB Accessory Cards

Board Name Description/Features
Bus Monitor Card with “blinkenlights” for monitoring the ECB bus and single-stepping the CPU.
Bus Extender Extension card which allows for ECB cards to be height-extended out of the chassis for easier debugging.
Prototyper C'T Projekt ECB bus prototyping card from C'T Projekt article.
Prototype w/I/O Decode ECB bus prototyping card with I/O Decode.

"Orphaned" ECB Cards

These are ECB cards which:

  1. Have no KiCAD or Gerber files available on the wiki
  2. Have no community member listed as a board distributor on the RetroBrew Computers Board Inventory page

These board could be “brought back” if KiCAD/Gerber files are located, or if someone is willing to re-enter the schematic into KiCAD and re-route a new board.

Board Name Description/Features
Active Termination A board which provides Active Termination to the ECB bus

Retired ECB Cards

Retired ECB Cards - .zip file archives with old information on cards which have been intentionally retired or superceded.
