Further to recent communications on this topic (for which many thanks to those persons) and some thinking I have a potential/possible reason that I would like comments on.
My thinking goes that if in the virtualisation setup I have the "disk" is not responding quickly enough for the RL driver in SimH then maybe it will return a buffer of zeros. Now even if I am on the right track for this, it leaves some questions (in no particular order): a) others have reported being able to use SimH 4.0 under virtualisation with no issues although not with RSX11M. So why would I be different? b) I would have thought that the driver for RL especially as it is emulating hardware would not "timeout" so quickly. c) If it did timeout, why have I not seen an error message? Maybe I need to look somewhere else ... hmm. And the obvious statement that I am completely wrong and it is something I have configured incorrectly either in the virtualisation environment (except it gives same error under both Virtual Box and VMware Workstation) or in SimH.

Have tried / been successful running it on a "native" O.S (not under VmWare or VirtualBox ?) I.e is the point to try to get it running under VmWare / Vbox .. or just it running period ? ;) Mike On 3/22/18, Phil Fisher <phil.fis...@peejayeff.co.uk> wrote: > > I have checked up some information and found the following.
