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,

I have a spare copy of the PET/CBM Personal Computer Guide Second Edition by
Adam Osborne & Carroll S. Donahue published by Osborne/McGraw-Hill
available. If you are interested make me an offer.

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

I have one also from my 16500C upgrade, if you need one.

For anyone who wants a copy, I just ran across a copy on eBay:
http://www.ebay.com/itm/161534172515
going for a more reasonable amount ($29, no bids at the moment).
The sale ends today (8:15PM EST).

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.
