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 Name | Description/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). DRAM memory up to 256Mb. Linux runs in 32Mb. |
| Mini-M68K | A Motorola 68008 processor board. Requires the Multifunction Controller (MF/PIC) board for I/O (see below). Runs CP/M-68. |
| 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. SDcard & IDE-8 (for CF card) interfaces on-board. |
| 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. |
| VDU | |
| VGA3 | 80×25 or 80×30 text display; operates at VGA frequencies to operate on a greater number of displays than the CVDU (above). Fonts are programmable. Includes an IBM PS/2 keyboard interface. Operates memory-mapped (for SBC-188 MSDOS), or registered access (similar to CVDU). |
| 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. |
| 4MEM | 4MB expanded memory board for SBC-188. Uses EMM4MEM.sys driver. Also expands SBC-188 memory to full 640K. Expanded memory is good for a battery-backed Ramdisk. |
| 4UART | Quad high-speed UART interfaces to RS-232 or USB at up to 3Mbps. 2 ports are dedicated to USB; 2 ports are USB or RS-232, selectable. |
| 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. |
| SCG | The “Sprite Color Graphics” is an ECB video display board based on the TMS9918 which features color graphics and sprite management. Board also includes AY-3-8910 sound support and dual joystick support. |
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:
- Have no KiCAD or Gerber files available on the wiki
- 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 |
