Nothing mythical.  There was a version of the corvus interface that
was a board that went under the Z80 and therefor allowed most any 
Z80 system to accept the corvus hardware.  It wasn't however sold as 
a uniquely Robin thing.

FYI the Robin does not have any for of external bus.  If you want 
access to the bus you have to jack up the Z80 and grab it there.

I ahve a Vt180, Vt185 (VT125+VT185 board) and maybe 4 VT180 boards
rigged as standalone and a dozen more if I need a Z80, 8k of shadow rom,
65K of ram, 4 serial ports and a FDC on one nice board.
