Re: [pups] Help! Standalone DZ-11 driver

I don't have a PDP-11, but I have done work in various ways with remote-device installs. If it were me I would prefer to be able to use a device distinct from the console, for several reasons: - a separate device might have an input silo (e.g. the DZ11 does); the console usually doesn't. A silo offers a little more robustness and may allow greater speeds. - it is better to keep the console available as a place for error messages to show up when things go wrong. - things are going to go wrong in any case, and I am going to have to try booting several times. If I have to get a serial-line switch or move cables back and forth, that is another thing that can go wrong, and another thing I can screw up. On the other hand, if I had the problem I would likely be happy to get any code that would help, whichever way it worked. So I also favour letting the implementor choose.

I also have a console input (DL-11, from memory). The input silo is potentially a benefit, but it's not a panacea by any means -- it has to be handled pretty carefully. -- isk -----Original Message----- From: norman(a)nose.cs.utoronto.ca [mailto:norman@nose.cs.utoronto.ca] Sent: Monday, January 29, 2001 2:13 PM To: pups(a)minnie.cs.adfa.edu.au Subject: Re: [pups] Help!
