No, chip mem is on board, and all the other custom chips need to be able to access it independently from the CPU. The Zeus is in the CPU socket, hence we can't fake chip mem, except for the CPU itself, which is not of much use.
I need to find out about SCSI.
As stated earlier, our plan is to deliver excellence, we don't care about production speed or cost. There's lots of stuff to be done office wise, like preparing accounts, getting quotes, making sure this gets properly taxed (the project will be managed and produced in Germany)... so... we're at it, while real life goes on.
