More DEC Alpha kit available, Newmarket UK

Folks, We have another pedestal ES40 and rackmount ES45 to give away, as well as a half-height Compaq rack (20U?). Has to be collected from CB8 7NY before the end of next week otherwise they get recycled. Anyone fancy an early xmas present? :) -- adrian/witchy Owner of Binary Dinosaurs, the UK'

Hi Mark, 3 minutes, that was impressive :) When can you head over to pick things up? Office hours are 9-5:30 every day, obviously you'd need a flatbed truck or van for everything. Cheers Adrian On 21/10/2016 11:28, "Mark Darvill" wrote: > Hi Adrian, > > Can I put my hand up to claim the sys

To solve the loading problem a division of Tektronix built their own Unibus repeater. We not only had a lot of stuff attached to the Unibus but was in multiple rack instruments. We also went with round cables the Tektronix made internally. We also made our own Unibus cables and added a few LEDs to

A friend of mine is working on an emulator for this Burroughs Large Systems beast. There is an existing one -- https://github.com/pkimpel/retro-b5500 But it's web-based and in Javascript. Mark wants one that can be run as a proper local binary, under Linux. I believe he's using part of this emula

I suspect it's the head servo. I've been trying to get a solid read out of the v170 I've been experimenting with all morning. It chugs along, recals, then a seek failure. I'd also like to understand the failure mode of Maxtor positioners. I had a 2190 croak (literally) as I was trying to read i

I'd trust the later documents. They went through a lot of pain in the 70's pushing the limits of what the bus could do. If it were me, I'd build the stuff on Eurocards with a cable running to a Unibus paddle. On 10/21/16 12:23 PM, Noel Chiappa wrote: > > From: Paul Koning > > > 1976 Peri

maybe the bounces from the DDNS attack today? Wouldn't be surprised. It was that serious. 8.8.8.8 may not have had problems, but anyone else using something from the attacked DNS provider would have come up gooseeggs, and maybe that bounced a lot of stuff the list sent out. Thanks Jim On 1
