hello all, I'm in the process of repairing our 101 but i hit a solid wall finding out whats wrong with it. are there people with a working copy who could do some measurements on their copy? Unfortunately i have no schematic of the electronics, only the mechanics and PSU. I have made a crappy video of the scope trace of the delay line input and i'm very interested in a video of a working machine's delay line. :-) The video is here: http://youtu.be/llpwjGeldt0 and a partially repairlog is here: https://hack42.nl/wiki/Repair_Olivetti_Programma_101 als scematics are welcome as well. :-) -- Met vriendelijke Groet, Simon Claessen drukknop.nl

Anyone have a spare DECstation in europe for a developer?

by abs＠absd.org

Bj?rn Johannesson has been working on the VAX framebuffer and keyboard code in NetBSD to get X running on the LCG equipped machines (like the VAXstation 4000/VLC and 4000/60). He's expressed an interest in looking at some issues in the DECstation X11 code, but doesn't have access to an appropriate machine. On the offchance, would anyone know of a little DECstation which might appreciate a new lease of life as a development box? :) Bj?rn is in Sweden, but I've heard that for the appropriate remuneration there are companies which will transport computers across oceans in (relative) safety :-p David

by linimon＠lonesome.com

So I triaged this unit the other day and now my company has listed it on eBay. It didn't come with the power brick so we couldn't test it; if you have one of these with its brick and need a spare, this is for you :-) http://www.ebay.com/itm/Rdi-Ultrabook-Sun-167MHz-or-200MHz-UltraSPARC1-256M… mcl

Weekly Classic Computer Trivia Question (20141226)

by dpi＠dustyoldcomputers.com

This one is seemingly easy. On the front panel of the original PDP-8 (straight 8), how many lights are there? There is a pretty good picture of one on Wikipedia if you feel like sneaking a peek. Doug Ingraham PDP-8 S/N 1175
