From mboxrd@z Thu Jan 1 00:00:00 1970 From: wes.parish@paradise.net.nz (Wesley Parish) Date: Fri, 02 Nov 2007 23:34:38 +1300 Subject: [pups] Suitable PDP11s, in the UK In-Reply-To: References: Message-ID: <200711022334.39669.wes.parish@paradise.net.nz> To add to this, there used to be a book on computer engineering with details on designing a PDP of some particular nature. (It might even have been a PDP-11.) Is it possible to persuade the writer of that book - a University textbook I think - to donate it to PUPS? Alternatively, does someone have an updated PDP-11 design that they would be willing to donate to PUPS for anyone with a soldering iron and enough time, to play with? I'm thinking this would be the way to solve this sort of problem in one fell swoop, if as I suspect is likely, it is impossible to find a working and available PDP-11 in the UK. Just my 0.02c worth - and my, hasn't inflation risen ... ;) Wesley Parish On Friday 02 November 2007 06:31, Tim Bradshaw wrote: > Having long ago got rid of my collection of ageing British (super) > minis, I realise I'm missing them, though I'm not sure why.
