68k homebuilts (FW: MC68000 ECB SBCs?)

Hi! I asked my friend Rolf in Germany about 68k home brew computers using ECB bus. Here is bunch of information on the subject which is in German. Fortunately the schematics are universal and there is Google Translate to handle the translation. He also has a nice photo shoot of the N8VEM SBC so you can see the home brew computer to give you an idea of what sort of system it is. http://www.hd64180-ecb.de/html/n8vem.html Although the N8VEM SBC may not be all that useful in a completed ECB 68k project, it could be used as a host processor while the 68k SBC is in development. If the /BUSRQ & /BUSAK lines are used, the 68k CPU can assume control of the ECB bus until the 68k releases it. That might be useful to use the Z80 SBC temporarily for a "kickstart" processor. In any event, the ECB backplane, ECB bus monitor, and ECB prototyping boards could be used "as is" with an ECB 68k SBC. Presumably developer could use the Disk IO and Terminal Replacement Board once those are completed as well. A 68k SBC certainly would be a welcome addition to the N8VEM project and I think you'd enjoy working with the team of builders. Thanks and have a nice day!
