Dec DMX11--What was it?

It is not possible to get ODT running without bank 0 memory.  All I get is output of 173000 and the no ability to input. cheers, Nigel On 2021-10-23 11:00 a.m., Noel Chiappa via cctalk wrote: > > From: Nigel Johnson > > > I will wait with bated breath! > > First things first; did you get
