Hi

Well, it is not just a WD1000 controller connected to the bus
with a bus buffer. The address register tells me that it is a
DMA controller. Although, the WD1000 controller can be connected
to a DMA controller, it can also be used in a polled mode.
You'd need to build a smart interface between the WD1000 and
the S8000 bus. It could be done with some PIC or other small
uP. You'd still need to build the DMA controller.

It is a selfmade WDC Controller using a Z80 for the calculation and so
on. If I cannot get my hands on a propper disk I might replace the whole
controller with a controller which access a IDE disk or similar. But
before I consider this, I need the tape part and the cartriges. Without
them I don't need any harddisk - I just don't have the ZEUS-OS which I
want to run on it ;)
